1.1 About DARWIN

Created from a completely new concept that is based on modular architecture, this group of next generation data acquisition systems is called DARWIN (Data Acquistion and Recording Windows). Today many data acquisition networks are increasingly being linked together. More than ever before, large volume, high speed, accurate, easy-to-use communication functions are essential in many disciplines. In the world of measurement and control where the number of measurement points has increased sharply, the ability to acquire information from a large number of points easily and economically is crucial. Interfacing to a personal computer allows simplified utilization of the information while improving quality and efficiency. DARWIN is based on a unique, new concept to meet these needs. The art of measurement is revolutionized by DARWIN which integrates functions of conventional recording and data logging. Most existing data acquisition equipment has been the all-in-one type in which the measurement section and display/recording section are contained in one box. While this simplifies operation on the one hand, it is difficult to adapt to changes in the measurement environment and also makes expansion difficult. DARWIN uses a data acquisition engine and remote I/O modules which are completely separate from each other. It is an entirely new product line which quickly and flexibly copes with various restrictive conditions and changes in specifications. Supported by a personal computer, a whole line-up can be created starting with the data acquisition systems DA series which performs data logging. For example, using a printer as the output device, the equipment becomes a hybrid recorder (DR series). Two models are available in the DR series: the DR230 and DR240. The DR 230 is a desk-top hybrid recorder, and the DR240 is a panel-mount hybrid recorder (component type).

1.2 Product Overview

This product is a hybrid recorder which can record and measure from small-scale 10-ch data up to widely distributed 300-ch multi-point data.

The number of measurement points can be expanded up to a maximum of 300-ch by connecting up to six subunits (DS400/DS600) to a main unit (DR232/242). Using dedicated extension cables between units, interconnections can be extended up to 500 m. Since measured objects scattered over a wide area can be wired fast and with a minimum of wiring, a flexible, extensive measurement system can be configured. The input modules to be incorporated in the DR232/242 or DS400/600 can be selected from the following, to suit your measurement conditions:

• Universal input module and DCV/TC/DI input module

Temperature, DC voltage and contact signals can be measured, but cannot be connected to the main unit.

• mA-input Module

This module can directly measure DC currents ranging from -20 mA to 20 mA since it contains shunt resistors. It cannot be connected to a system's main unit.

• Power Monitor Module

This module can measure the effective voltage, effective current, active power, reactive power, apparent power, frequency, power factor and phase angle for an AC voltage or AC current input. It is available in either a single-phase or three-phase model. This module cannot be connected to a system's main unit.

• Strain Input Module

This module can measure strain. It is available in either a model with built-in 120- or 350-Ω bridge resistors or a model with NDIS terminals where bridge resistors are connected externally. The module cannot be connected to a system's main unit.

• Pulse Input Module

This module can measure pulses. It cannot be connected to a system's main unit.

• Digital input module

This module can measure contact signals. It cannot be connected to a system’s main unit.

• Communication interface module

This module is necessary when communicating with a personal computer. Measurement conditions can be set and data acquired via the communication interface (GP-IB, RS-232-C, etc.) of this dule. This module can only be connected to the main unit.

• Alarm module

This module can output alarm signals as contact signals. The module can be connected to the main unit or the subunit.

• DI/DO module

This module allows a signal to be output in the case of alarm, failure, or chart end and a remote control signal for the product to be input. The module can be connected to the main unit or the subunit but only one module in all units.

2.2 Measurement Input Functions

Input Type

DC Voltage

Measurements can be done after selecting the measurement range per channel. The minimum range is 20mV, the maximum range is 50V.

Thermocouple

Measurements can be done after selecting the type of thermocouple per channel. The available types are R, S, B, K, E, J, T, L, U, N, W and KPvsAU7FE. Reference Junction Compensation (RJC) can be set to either use Internal RJC (INT) or External RJC (EXT) per channel. Burnout function can be set OFF per channel or it can be selected in which direction the trend line will move if burnout occurs (right or left)

Resistance Temperature Detector

Measurements can be done after selecting the type of resistance temperature detector (RTD) per channel. The available 17 types are Pt100(1mA), Pt100(2mA), JPt100(1mA), JPt100(2mA), Pt50(2mA), Ni100(1mA)SAMA, Ni100(1mA)DIN, Ni120(1mA), J263*B, Cu10GE, Cu10L&N, Cu10WEED, Cu10BAILEY, Pt100 (1mA) high resolution, Pt100 (2mA) high resolution, JPt100 (1mA) high resolution and JPt100 (2mA) high resolution.

Contact Input

The type of contact input can be selected from voltage level input or contact input, and recording can be set ON or OFF per channel. In case of the voltage level input a voltage level up to 2.4V results in recording OFF, whereas a voltage level of 2.4V or more results in recording ON.

Functions

DC Currents

DC currents ranging from -20 mA to 20 mA can be measured by means of the built-in 250-Ω shunt resistors.

AC Voltages/Currents

The effective voltage, effective current, active power, reactive power, apparent power, frequency, power factor and phase angle can be measured. The measuring range is common to all terminals. The input terminals of the module with this input mode, unlike those of modules with other input modes, are not consistent with a setup screen in terms of the channel number.

Strain

The module for this input mode supports the single-gauge, single-gauge three-wire (not yet supported by the DU500-14 module), adjacent-side two-gauge, opposed-side two-gauge and fourgauge methods. If you have connected any new strain gauge or changed the measuring range, go through initial balancing before starting measurement.

Pulses

The module for this input mode can measure the number of pulses per second on a channel basis or detect the on/off states by means of any variations occurring in the instantaneous value every second. Once you connect the pulse input module, you can sum up values without the need for the computing function.

Skipping Input Channels

This function allows skipping measurement, recording and display of channels you are not using. Measurement, recording and display will not be done for the skipped channels.

Reference Junction Compensation (RJC)

This function is to be used when measuring temperatures using thermocouples. The voltage generated by a thermocouple depends on the temperature of the spot of measurement and the reference junction temperature. Reference junction compensation is a function which compensates the temperature at the side of the measurement instrument to 0 degrees C. To compensate for the environmental temperature an internal circuit can be selected, or compensation by a fixed compensation voltage value (external) can be set.

IM DR232-01E

2-3

2.2 Measurement Input Functions

Scan Interval

• The duration of time (one scan) in which the measurement of all channels is carried out, is called the scan interval.

• This interval can be set to any value from 0.5 second to 60 seconds. The shortest is 300 ch/500 ms (varies with the shortest measurement period of the input module).

A/D Integration Time

This instrument measures the input signal after putting it through an A/D converter. In order to minimize the noise imposed on the input signal, specific integration times exist. The integration time can be selected from 20ms (50Hz), 16.7ms (60Hz) and 100ms (10Hz). When “AUTO” is selected, the integration time will be automatically decided according to the 50/ 60Hz frequency of the power supply. AUTO does not function if the instrument is the subunit (DS400/DS600) of the DC power supply model (Selecting “AUTO” will set the A/D integration time to 20 ms (50 Hz)). If you are using the instrument on a 60-Hz power supply, set the A/D integration time to 16.7 ms (60Hz).

Input Filter

A filter can be set ON/OFF to reduce normal mode noise. Effects on normal mode noise are as follows depending on the filter being ON/OFF (theoretical values).

2.3 Recording Functions

Chart Speed

The speed at which the chart moves when performing trend recording can be selected from any value between 1 to 1500mm/h. Two types of chart speeds can be set. When you are not using the Event/Action function, which will be described later on in this manual, chart speed 1 will be valid. When the Event/Action function is being used, you can select whether chart speed 1 will change to speed 2 according to the event status.

Recording Mode

Two types of recording modes are available; analog trend and logging mode. The default setting is analog trend mode.

Analog Trend Mode (refer to the next page for a recording example) Trend Recording (Dot recording)

The recording principle is that, according to measurement data and recording conditions, the correct position on the chart will be decided and on that position the dot will be printed. Trend recording conditions consist of the following.

• chart speed

• channels to be recorded

• recording color (refer to page 2-8)

• recording interval (refer to page 2-8)

• recording span (refer to page 2-9)

• recording zone (refer to page 2-9)

• partially expanded recording (refer to page 2-10)

• interpolation function (refer to page 2-10)

Functions

Digital Printout

Measurement data will be printed as numerical values. Digital printout conditions consist of the following.

• channels to be recorded

• recording interval (refer to page 2-8)

• the number of channels to be recorded on the same line (refer to page 2-7)

Logging Mode

In this mode measurement data are only printed as numerical values. Logging recording conditions consist of the following.

• channels to be recorded

• the recording direction (vertical or horizontal)

• recording interval (refer to page 2-8)

2.3 Recording Functions

Recording Colors

Recording Interval

In the trend recording the color of the recording can be selected per channel. The colors which can be selected are black, purple, redish purple, navy blue, red, blue, brown, green, orange and yellowish green. The recording color of the numerical values in the logging mode is purple only.

The time during which one scan of trend recording or numerical printout is carried out is called the recording interval.

Recording interval for trend recording

This recording interval can be selected from AUTO or FIX.

AUTO

The recording interval is decided automatically depending on the measurement (scan) interval and chart speed in order prevent the dots from overlapping. However, in cases where this calculation would render the recording interval smaller than the scan interval, the recording interval will equal the scan interval.

Recording interval = Scan interval × N

where N is an integer satisfying N fixed.

Example: when scan interval is 2s; chart speed is 100mm/h

then N ≤ 720 / (2 × 100) = 3.6 The closest matching integer is 3. Accordingly, the recording interval becomes 2 × 3 = 6s.

≤ 720 / (scan interval × chart speed). 720 is

FIX

Recording is carried out at an interval which is the same as the scan interval (2 to 60s) regardless of the chart speed.

Recording interval for digital printouts

This recording interval can be selected from MULTIPLE or SINGLE

MULTIPLE

Six preset recording intervals (Timer 1 to 6) can be set and a recording interval can be selected per channel. The timer setting can be selected from relative and absolute.

• Relative time: Time will be counted from the point of turning the power switch ON or of resetting the timer. Each time the preset length of time is reached (and thus when time is up), recording will start.

• Absolute time: A reference time is set, and from that time recording will start at preset time intervals (each time when time is up).

SINGLE

The logging interval is decided automatically depending on the chart speed and the number of columns for digital printouts.

Recording interval in logging mode

This recording interval can be selected from MULTIPLE or SINGLE

MULTIPLE

Same as for the analog trend mode

SINGLE

From the above mentioned six preset recording intervals, the interval set as Timer 1 will become the recording interval.

Resetting the Recording Interval (Timer Reset)

This function will reset the elapsed time of the above mentioned MULTIPLE recording interval to zero. Usually recording will start according to the recording intervals, but when you reset the elapsed time using this function, the results are the same as for time-up.

2-8

IM DR232-01E

Recording Span

The maximum value and the minimum value of the measurement range are decided when setting the type of input. The difference between the minimum value and maximum value which will be recorded within this measurement range, is called the recording span. The value on the left and right side of the recording are called the left span and right span respectively.

Starting/Stopping Recording

Usually starting/stopping movement of the chart and trend recording is carried out by pressing the appropriate key on the operation panel. But movement of the chart and trend recording can also be started/stopped upon alarm occurrence or by remote control (event/action function).

Recording Method of Trend Recording

Chart movement can start by either key operation or event/action function and selected channels will thus be recorded as trend recording.

Normal Recording

Selected channels will all be recorded regardless of the below mentioned occurrence/release of alarms or group settings. Recording will start when the chart starts moving.

Trend Recording upon Alarm Occurrence

• Trigger Recording

All channels where an alarm occurred will be recorded. Even when the alarm is released, recording will continue.

• Level Recording

All channels where an alarm occurred will be recorded. When the alarm is released, recording will stop.

Group Trend Recording

Channels can be clustered in a group, and only those channels will be recorded.

2.3 Recording Functions

Functions

Recording Zone

Scale Values

The recording span of measurement values on the chart is called recording zone. For each channel you can set between what locations on the chart the measurement values will be recorded. It is possible to assign zones so that the analog trend recordings of each individual channel will not overlap. This setting is only valid for trend recordings in the analog trend mode. The default setting is the full recording width of 250mm. The left and right boundary of the recording zone (left position and right position respectively) correspond to respectively the left and right span of the recording span.

Trend of channel 1

Left position of zone 1

(=left span of ch1)

Zone 1 Zone 2 Zone 3

Right position of zone 1

(=right span of ch1)

Trend of channel 2 Trend of channel 3

Scale values are used to mark the divisions of zones and three different scale format can be selected.

2.3 Recording Functions

Partially Expanded Recording

When carrying out trend recording, partially expanded recording enables you to compress a part of the recording span in order to examine the expanded (other) part of the span in more detail. The left boundary of the recording span being 0%, and the right boundary of the recording span being 100%, a segment of the recording span can be compressed. The following example shows a situation where 25% of the recording span has been compressed. The points A, B, C, D, E and F before compression correspond to the points A’, B’, C’, D’, E’ and F’ in the figure after compression. The 25% left of the boundary shows —6 to 0V, whereas the 75% right of the boundary shows 0 to 6V.

When carrying out trend recording and a measurement value differs greatly from the previous one, the track of the recording changes stepwise in the dot printing. In cases like this, interpolation will be carried out on the horizontal line to connect the two divergent trend tracks. When the horizontal lines of channels are to be recorded on exactly the same location, only the recording color with the higher priority will be used. The priority of recording colors is black > purple > redish purple > navy blue > red > blue > brown > green > orange > yellowish green, which means that black has the highest priority. In the figure below a recording example is given of a horizontal line in the colors black, red and yellowish green. In the area where red and yellowish green overlap (labeled as a), only red dots will be recorded, and in the area where black, red and yellowish green overlap (labeled as b), only black dots will be recorded. However, at the locations where the recordings diverge after the connecting a horizontal line, all

recording colors will be recorded.

2.5 Standard Computation Functions

Standard computations such as difference between channels and linear scaling can be set with measurement input settings. A moving average computation is also available.

Difference between Channels

This function conputes the difference between the measurement values of a selected channel (=reference channel) and any other channel (=destination channel). This can be applied to each channel in the same unit. The computation formula is as follows:

Result of difference between channels computation = measurement value of destination channel — measurement values of reference channel

Linear Scaling

This function changes the left and right span of the recording span to left and right scale values which are converted to a different physical quantity. This can be applied to each channel and a different engineering unit can be entered for display and printouts.

Example where voltage values are cenverted into linear scaling values

Moving Average

Left span:-2V

(=left scale:-0.1A)

Right span:2V

(=Right scale:1.1A)

This function computes a moving average over a preset number of (K) measurement values. This function is useful for displaying and recording of unsteady measurement values. The computation formula is as follows.

m= (Mm-(K-1) + Mm-(K-2) + ... + Mm-2 +Mm-1 + Mm) / K

where D

m : “m”th average value

m-(K-1) : the measurement value of the “K-1”th measurement before the “m”th

measurement

m-(K-2) : the measurement value of the “K-2”th measurement before the “m”th

measurement .. ..

m-2 : the measurement value of the second last measurement before the “m”th

measurement

m-1 : the measurement value of the last measurement before the “m”th measurement

m : the measurement value of the “m”th measurement

K : number of samples, and an integer ranging from 2 to 64

At the first computation, the measurement value of the first measurement will be multiplied by the number of samples, after which the average will be taken. The measurement values of the second and later measurements will replace these in turn, after which the average will be calculated each time.

• Panel mounting

Use steel plates 3 mm thick or more for panel mounting. The external and panel cutting dimensions for the DR242 are shown below. The panel cutting dimensions include the cutting interval for multiple mounting on the same panel. The DR242 weighs about 12 kg, so a shelf should be provided to support the DR242 behind the panel. Insert the instrument from the front face of the panel. Insert the blocks of the mounting brackets as accessories into the rectangular holes (after removing seals) on right and left sides of the instrument, push the brackets toward the rear, and engage the blocks with rectangular holes. When a screw attached on each bracket is turned clockwise, the entire brackets are pushed against the panel rear. Tighten the screws to securely fix the instrument to the panel. Proper screw-tightening torque is 0.8 to 1.2 N·m (8 to 12 kgf·cm). The brackets can be used for panels of 3 to 26 mm thick.

3.3 How to Connect the Input/Output Modules

WARNING

When connecting the Input/Output modules, make sure to turn OFF the power to the DR232/DR242/DS400/DS600 to prevent an electric shock or damage to the instrument.

Setting the Unit Number of each Subunit

When connecting subunits to the DR232/DR242, it is necessary to assign a distinctive unitnumber to each subunit. This number can be selected from 0 to 5 (the setting 6 and up will not be recognized) and is set, as shown in the figure below, by a setting switch (rotary dipswitch).

Note

When you connect an input module at the location of the setting switch, the switch can not be operated anymore. Therefore, make sure you set the switch before connecting any input module there. It is convenient for confirming unit numbers to write each unit number setting on the gray concave surface at the top of DS600 subunit (or on the left side of DS400 subunit).

Connecting Method

1. Verify that the power to the DR232/DR242/DS400/DS600 has been turned OFF.

2. Remove the cover of the location where the module will be connected. Do not remove any cover of locations where no module will be connected.

3. Hold the input unit so that the male part of the connector at the back side of the input unit matches the female part of the receiving connector. Then connect the unit.

4. Fasten the input unit by fastening the two accessory M3 screws.

• Main unit DR232/DR242

Alarm module, DI/DO module, and communication interface module. (Note: The input module cannot be connected.) Number of modules that can be connected: 1

• Subunit DS400/DS600

Input module, alarm module, and DI/DO module. Number of modules that Dqn be connected: 4 for DS400, 6 for DS600 (up to 300)

DS400: Input module + alarm module + DI/DO module: max. four DS600: Input module + alarm module + DI/DO module: max. six

Note

• No alarm module or DI/DO module can be connected to the right side of an input module, since the rise

in temperature would hinder the measurement accuracy. Verify the type of module by the seal on the top side.

• Do not connect the universal input module and the power monitor module in slots next to eachother.

Keep them at least 1 slot apart. If you mount the power module immediately beside the universal module, the measuring accuracy of the universal module may fall out of its guaranteed range because of the heat radiating from the power module.

Installation and Wiring

Extension cable

Note

• Connection (including addition or replacement)/removal of subunits, or unit number setting (see page 3-

• Mounting (including addition or replacement)/removal of modules

Points to Note when Using the Extension Cables

• The maximum rated temperature is 60°C;

• Never disconnect the extension cable from the connector by pulling the cable, since this might

damage the signal cable. Always hold the plug.

• When wiring the extension cable through a cable duct, or metal pipe or such, protect the peg on top of the plug by covering it with tape.

• For extension cables of longer than 50 m connect the plug with copper foil directed towards the main unit DA100. Applying it in reverse direction might increase noise.

• Fasten the cabels in such a way that no force is applied to the connector or the plug.

• To prevent the wire from snapping, etc. do no apply a tensile force of more than 70N.

Furthermore, do not bend the cable in a radius of 3 centimeters or less.

• For the environmental conditions for wiring, refer to Section 3.11, “Countering Noise” (page 3-

35).

Note

When several sub-units are connected, and the power is turned off of one of them, the other connected subunits which are further away from the main unit will not be recognized anymore.

3.7 Connecting the Signal Lines

W WARNING

• To prevent electric shock, always make sure that the power supply is turned OFF before connecting.

• When 30 VAC or 60 VDC and more is applied to the output terminal of the alarm module or the output terminal of the DI/DO module, use double-insulated wires(withstand voltage performance: more than 2300 VAC) for those wires which apply 30 VAC or 60 VDC and more. All other wires can be basic-insulated(withstand voltage performance: more than 1350 VAC). Furthermore, use “crimp-on” lugs (for 4 mm screws) with insulation sleeves for connecting to the screw terminal. Make sure that the crimp-on tool must be one specified by the crimp-on lugs manufacture, and that the crimp-on lugs and tool must be matched to the wire size. To prevent electric shock, do not touch the terminal after wiring and make sure to re-apply the cover.

CAUTION

• Do not apply an input voltage exceeding the following levels to each terminal of each module. Otherwise, the internal circuits may be damaged. Allowable input voltage

Universal or DCV/TC/DI input module

2 VDC range or less, RTD, TC and DI(CONT) : ±10 VDC 6 to 20 VDC range, DI(LEVEL) : ±60 VDC

Note

Make sure that the equipment connected to the signal in-/output conforms IEC (CSA) 950 or IEC (CSA)

1010. Also, make sure to use cables that conform to IEC (CSA) standards. In case you are using an internal RJC in case of thermocouple input, the following considerations are necessary to stabilize the temperature at the terminals. Always make sure to re-apply the terminal cover; The thermal capacity of the wiring should be small (cross sectional area of less than 0.5mm2); Minimize outside temperature fluctuations as much as possible. To prevent noise, make sure to ground each unit at the grounding function terminal (below the power switch) together at one point. Refrain from wiring the input signals parallel. However, if you do, then the following considerations are necessary. Ground all equipment at the same point; Do not turn the power of other equipment ON/OFF during operation; Do not use the burnout function.

3.7 Connecting the Signal Lines

Wiring AC Input Signal Lines (Power Monitor Module)

WARNING

• For hazard prevention, ALWAYS provide protective grounding before connecting measuring leadwires.

• When connecting any object being measured, ALWAYS turn off the power to the object. It is extremely dangerous to connect or disconnect interconnecting leadwires with the power to the object left on.

• Exercise utmost care to avoid connecting any current-mode circuit to a voltage-input terminal or any voltage-mode circuit to a current-input terminal. Wrong connection may result in damage to the circuit or equipment being measured or the DR232 or DR242 recorder itself, as well as bodily injury.

• Fuses are not built into voltage- and current-input terminals. ALWAYS install a fuse on the interconnecting leadwire. Use a fuse that will not permit the voltage or current being measured to exceed the maximum ratings of an AC input module. The maximum voltage and current that can continuously be imposed on an AC input module are as follows: Voltage: 250 Vrms; current: 5 Arms

• To avoid electrical shock, ALWAYS attach the terminal cover in place after the completion of wiring to the terminals so that the terminals

cannot be accidentally touched.

CAUTION

• In wiring, use double-insulated leadwires that have sufficient withstanding-voltage and current-carrying-capacity margins against the voltage and current being measured and meet the ratings at which they are used.

• ALWAYS clamp measuring leadwires with the wire clips to prevent the wires from being disconnected from their terminals. As the measuring leadwires, use wires 0.2 to 2.5 mm2 (AWG14 to 25) thick so they can be fastened securely with the wire clips.

• The power monitor module is a product belonging to Installation (Overvoltage) Category CAT II.

3.8 Connecting an Extension Module to Extension Bases

Using an extension module and extension bases, you can install input modules at a location distant from the sub-unit(s). The module and bases are powered from the sub-unit and, therefore, can be located even in a place where there is no power source nearby.

Installing an Extension Base

WARNING

• For fire prevention, use extension bases in an upright position. Do not cover up the extension base's module (allow a clearance of at least 3 cm around the module).

Ambient Temperature and Humidity

Use an extension base under the following environmental conditions:

• Ambient temperature: –10˚ to 60˚C

• Ambient humidity: 20 to 80% RH at -10˚ to 40˚C

10 to 50% RH at 40˚ to 50˚C 5 to 30% RH at 50˚ to 60˚C Use the extension base in a condensation-free condition.

Note

Condensation may occur if you move the extension base from an area of low humidity to an area of high humidity or if any drastic temperature variation takes place. In addition, a measurement error will result if the DR recorder is in the thermocouple input mode. In that case, allow at least one hour for the extension base to adjust to the ambient atmosphere before using it.

Do not install the extension base where:

• it is exposed to direct sunlight or there is a heat source nearby;

• soot, steam, dust and/or corrosive gas is relatively abundant;

• there is a strong electromagnetic source nearby;

• there is high-voltage equipment or a power line nearby;

• it is exposed to severe and/or frequent mechanical vibration; or

• it is not positioned stably.

Desk-top or Floor Installation

Attach the two supplied shoe plates onto the extension base with two screws (4-mm screws 16 mm long, supplied as standard accessories), as shown in the figure on the left below. Then, place the extension base in an upright position. If the base is liable to fall on its side after wiring, fix the shoe plates with the four supplied screws (4-mm screws 12 mm long) using the through-holes (for 4-mm screws) of the shoe plates.

Direct Mounting on Panel

According to the figure on the right below, fix the extension base onto a panel by fastening the four corners with the supplied screws (4-mm screws 12 mm long).

IM DR232-01E

3.8 Connecting an Extension Module to Extension Bases

Connecting Extension Bases to an Extension Module

Verify that the power of the DR/DS400/DS600 has been turned off before connecting the extension module/extention base. Mount the extension module onto the sub-unit. The module cannot be mounted to the DR recorder itself. Wire the extension module to the extension base with an extension cable. You can wire a maximum of three extension bases to one extension module at the same time. It is not possible, however, to wire extension bases in such a manner that the total sum of modules already mounted on the sub-unit and the extension bases being wired exceeds the maximum number of modules (four for the DS400 sub-unit and six for the DS600 sub-unit) allowed for mounting on the sub-unit. Either a 10-channel universal input module (DU100-11 or DU100-12) or a 10-channel DCV/TC/ DI module (DU200-11 or DU200-12) can be mounted onto each extension base.

3.11 Countering Noise

Types and Features of Noise Sources

Commercial Power Supply

It is necessary to consider both 50 and 60Hz as noise components. It is important to note that a power supply line in which a thyristor or inverter is incorporated functions not only as an “energy surplus line”, but also as a “supply surplus line”.

Thyristor (SCR)

A thyristor is used to control power through ON/OFF modulation of commercial power by controlling the phase angle.

phase angle

Thyristor waveform

Current

When the thyristor turns ON or OFF, a pulse noise is superimposed on commercial power supply, and its pulse width is approximately 1µs. Accordingly, thyristor noise can be defined as follows.

· thyristor noise = commercial power supply + pulse noise

Inverter

Commercial power supply is converted to direct current by a rectifier (sometimes the thyristor is used as the rectifier to stabilize direct current) and then modulated by a switching transistor and finally converted into alternating current at the desired frequency (from tens to hundreds of Hz) to drive a motor, for example. If the load to be driven is a fluorescent lamp, the frequency is tens of kHz. Accordingly, inverter noise can be defined as follows. Inverter noise = commercial power supply + pulse noise (high density) + variable low frequency noise Since the density of pulse noise is high compared to that of a thyristor and in addition, there is variable frequency noise, it is difficult to consider a countermeasure for inverter noise.

Propagation of Noise

Relay

A relay is frequently used to amplify alarm and temperature controller outputs. However, since a counter-electromotive force (counter e.m.f.) is produced by coil inductance when the relay is turned off and the e.m.f. becomes noise, care must be taken. Due to chattering at the relay contact, tens to hundreds of kHz noise occurs mainly in bursts. Thus, the noise energy often becomes high.

Transceiver

In large-scale plants, transceivers are often used for communications between the field and the control room. Although W/G of the Japanese Electric Measuring Instruments Manufacturers Association recommends to use transceivers covering a wave band of 27MHz, smaller-sized transceivers for the 140 or 470MHz wave band are often used.

Noise Simulator

To test the immunity to pulse noise (mainly thyristor noise), a noise simulator is often used. A test noise of approximately 1kV for 0.8µs is used synchronously with the power supply frequency. Since data acquisition equipment is often used for measurements of equipment subjected to the pulse noise test, the influence of noise must be considered.

• Noise is propagated in the following three ways.

Conduction: noise is conducted through a power line, input wiring, etc. Electrostatic induction: noise leaks through capacitances between wires and instruments. Electromagnetic induction: a loop in the input line, etc. induces an AC voltage by detecting the

AC magnetic field. In real applications, the above three propagation paths are not independent of each other. Their combination propagates noise to the equipment and causes problems.

IM DR232-01E

• Examples of noise propagated through each of these paths are given below. Conduction: inverter noise, relay noise, thyristor noise, and noise caused by

surface temperature measurement of a power transistor, etc. Electrostatic induction: commercial power supply noise such as the hum of audio

equipment, relay noise, etc. Electromagnetic induction: magnetic leakage flux from a power transformer or motor, magnetic

field from a high-frequency induction furnace, the rotating magnetic

field of a power generator (Cu10Ω), etc.

The figure on the next page shows the propagation paths using practical examples.

This is an unfavorable noise that is superimposed on a signal voltage. Since it is a voltage between the H and L terminals, it is also called the line voltage, or since it is a voltage in series with the signal voltage, it is sometimes called the series mode voltage.

IM DR232-01E

3.11 Countering Noise

In the figure on the previous page, due to common mode voltage ECM, noise currents i1 and i flow through the impedance to grounds Z1 and Z2 and coupling impedance Z3, resulting in the generation of normal mode noise E noise is converted to normal mode noise. The amp is equipped with a built-in filter and in case of output E

the normal mode noise will be eliminated. This rate of conversion is called the

common mode rejection ratio and expressed by the following equation.

• Common mode rejection ratio

Since the actual CMRR is expressed using the ratio of an error component output caused by common mode noise to common mode noise, it contains the normal mode rejection ratio (NMRR) expressed by the following equation.

• Normal mode rejection ratio

The NMRR is a value that shows the ability to reject the output error (normal mode noise component: E

) by normal mode noise. Thus, this is also a very important value which shows

the resistance-to-noise characteristics of the measuring instrument.

Basics of Anti-Noise Measures (part 2)

Decreasing and Increasing Impedance

As described in the previous section, conversion of common mode noise into normal mode noise causes an error in the measured output. In other words, prevention of such a conversion is the key to anti-noise measures. As can be understood from the previous section, it is important to take the following measures to reduce normal mode noise.

· reduce the wiring resistances R

· increase the coupling impedance of common mode voltage E

These are called the decrease and increase of impedance as basics of anti-noise measures. In the above discussions, anti-noise measures have been described on the assumption that common mode noise has already been given. In real applications, common mode noise often occurs owing to grounding resistance as shown in the figure below.

Anti-Noise Measures in the Instrument Itself

Pulse width modulation type A/D converter (PWM type A/D)

This instrument uses a feedback pulse width modulation type A/D converter and has the following features:

• Linearity and stability are good because of the feedback effect.

• Integration type A/D converter ensures excellent noise suppression.

If the integration time is equal to the noise period, the positive and negative sides of the shaded part in the figure below cancel each other out and thus the average value becomes zero.

integration time

Normally, an integration time of 20ms (50Hz) or 16.7ms (60Hz) is selected depending on the commercial power supply frequencies. A 100-ms integration mode is added to the instrument to achieve superior noise rejection. However, when using the 100ms setting, the smallest measurement interval is longer than in case of the 20ms or 16.7ms setting. The integration effect enables the PWM A/D converter to perform the following two functions.

• Rejection of frequency determined by the reciprocal of the integration time and frequencies which are whole multiples of that frequency;

• First-order lag filter provided with cut-off frequency proportional to the reciprocal of the integration time.

The following table compares the integration times of 16.7ms, 20ms and 100ms.

Integration time Rejection frequency Cut-off frequency Remarks

16.7ms n×60Hz approx. 19Hz for 60Hz

20.0ms n×50Hz approx. 16Hz for 50Hz

100.0ms n×10Hz approx. 3.2Hz for both 50Hz/60Hz

n=1,2,3...

As shown in the table, the merit of 100.0-ms integration is not only that it applies to both 50 and 60Hz, but also that it provides a low cut-off frequency as the first-order lag filter and improves the noise rejection ability. The following figure shows the calculation values of the NMRR for three integration times and an example of actual measurement of the NMRR for a 100-ms integration signal.

3.11 Countering Noise

• Shielded and twisted pair (prevention of electromagnetic coupling): an increase of impedance

If it is difficult to keep the noise source away from the measuring instrument due to space limitations, the use of a shielded twisted pair is effective.

• electrostatic coupling can be completely cut off by shielding;

• for a magnetic field, shielding with a magnetic material (iron, permalloy, etc.) can be

employed. However, there are many restrictions on this use and perfect shielding is impossible. Therefore, use of a twisted pair is preferable.

Voltage e

induced by the coil is proportional to the area of the coil.

=> The smaller the area of the coil becomes, the smaller the noise becomes.

Coil

Magnetic field Φ

If the directions of coils 1 and 2 are reversed by twisting, as shown, if the areas of the two coils are equal, the induced voltages of the coils offset each other and total induced voltage em becomes zero.

3.11 Countering Noise

• Relay noise suppression

<DC relay> To prevent noise and protect the contact, connect the diode to the relay coil terminal directly. In addition to the above measure, reduce the rated voltage of the relay circuit as much as possible for higher reliability. It is necessary to choose a diode that matches the relay. Generally, a diode whose rated rectifying current is at least three times the current flowing through the relay coil must be used. And the rated reverse voltage must be at least three time the operating voltage.

(Note) Across the relay or solenoid coil, a counter-electromotive force is produced by an

inductive load. This phenomenon may damage the contact or, as the noise source, cause a malfunctioning of the equipment, and have an unfavorable effect on the entire system.

<AC relay> If a relay contact is connectd to the input of the system components, apply the measure shown in the figure at the right to the relay coil. Otherwise, a counter electromotive force produced across the coil may be induced on the contact side through the relay's internal coupling or coupling between the lines, and may cause a malfunctioning of the equipment.
