Mechanical Installation

q

Each I/O module, except the Display v ar iety, is enclosed in the same standard plas tic case that is designed to be mounted on a standard DIN rail or fastened to a panel.

Note: In order to meet agen cy requirements, it is necessary that the modules along with the power supply and controller be housed in another metal enclosure i.e., a NEMA box or the new Andover Controls Cont in uu m enclosure.

The standard I/O module plastic case is illustrated below:

Status Indicators & some switches

Status indicat or s and oper ator switches are located on the indicat or panel. Other switches available for m odule c onfiguration may be access ed by lifting the hinged door to the module as shown.

Andover Controls

Wiring to controlled points or sensors is accomplished via a standard removable screw terminal block locat ed at the bottom of the module behind the door. A n open area at the bottom of the case allows wires to exit in an appropriate manner.

On the back of each module are molded DIN r ail guide fingers. The design allows the module to easily hook onto and s lide along a s tandard DIN rail.

Locking Fingers

With the mounting brack ets extended outward, hook the module ont o the DI N r ail as shown below:

Power-CPU Connections

The Continuum NetCont r oller CP U m odule inc ludes a c onnec tor on the upper right side of its case for further distribution of the 24 VDC input power and special I/O communications signals to all I/O modules. Continuum I/O modules us e these signals for power and communications as well.

The power-I/O connec tor is a five pin male assembly that is designed to easily ins er t directly into t he left s ide ( input) connector of any I/O module. The signals wit hin that connector are as follows:

PIN Function

5 +24 VDC 4 24 VDC Return 3 Ground 2 Comm B 1 Comm A

5

The system power supply gener ates a +24 VDC source for all modules in the system. This power source is received through the input power connector on the left side of the CPU module and sent through t o pins 4 and 5 of this connec tor. Pin 3 (Ground) is intended as a signal ground connect ion.

Communications between the CPU and I/O modules is through a two-signal s er ial interface that can be internally configured as eit her RS 485 or Echelon LON FT T-10. Pins 1 and 2 (Comm B and Comm A) provide the elect r ic al c onnec tion for this interface.

Connection of I/O Modules

y

The CPU can directly connect to I/O without the use of cables through a syst em of built-in plugs and jacks. All I/O modules include two complementary module interconnectors.

Creating a system is as simple as physically plugging the modules together.

Power Suppl

CPU

I/O

In vertical extended systems, I/O modules may be located above or below other modules. In this case, cable as s em blies br idge the I/O modules together.

The cable necessary to connect the CPU and external I/O modules is five c onduc tor and would be attached using a plug-in screw terminal connector. Connection between the modules is one-to-one straightforward wir ing as s hown below:

Maximum Number of I/O Modules

There is no operational limit to the number of I/O modules connected to the CPU except the capacity of the power s upply . It is pos s ible to insert auxiliary power supplies int o the I/O bus to increase the num ber of modules s uppor ted.

To determine the maximum number of I/O modules your system can support, subtract the power requirements f or eac h module fr om the max im um available f r om y our power supply.

PS 120/240 AC 50 U, UPS power supply provides 35 Watts of power

•

PS 120/240 AC 50, non-UPS power s upply pr ov ides 50 Watts of power

•

PS –48 DC 50, Battery operated power s upply pr ov ides 50 Wat ts of power

•

NetController requires 15 Watts of power

•

Start by subtracting the NetController from the power available from your power supply.

PS 120/240 AC 50 U

35 – 15 = 20 Watts of available power for I/ O

PS 120/240 AC 50

50 – 15 = 35 Watts of available power for I/ O

PS –48 DC 50

50 – 15 = 35 Watts of available power for I/ O

The power requirements for each I/O module is listed in the

Reference Guide

ACC # 30-3001-499 and can be found on individual dat a s heets.

Continuum I/O System

Maximum Length of I/O Bus

A repeater is necess ar y if the cable lengths get too long. The following are recommendations regar ding c able lengths for both RS-485 and FTT- 10 interfaces:

RS-485 Repeater required if lengt h is >2000 ft. (610 m) or after 32 modules. FTT-10 Repeater required if lengt h is >8858 ft. (2700 m) bus topology

>1640 ft. (500 m) free topology

Connecting Remote I/O Modules with RS-485

The Continuum system allows I/ O modules to be placed in a remote location from the CPU (NetController) . However, long cable lengths can cause s ignal c om m unic ations problems on the Power/I- O bus.

When locating an I/O module remotely it is necessary to add a 120

terminator to the

Ω

bus to compensate for the distance. The terminator must be connec ted at both ends of the bus for proper operation.

Terminat i on Guidel ine s

The following are typic al ins tallations that indicate the placement of the terminator:

Simple CPU and 1 remote I/O Module:

The I/O Bus that needs to be term inated is the one formed by the cable attaching the remote module to the CPU. In this c as e, a t erminat or r es is tor is connected across the communications lines ( pins 1 & 2) directly at the NetController and again at t he r em ote I/O module.

Individual Module Characteristics

This section of the document describes the various I/O modules and presents interfacing information. E ac h module is pres ented in its own mini-section. The part number designator for the module being described is printed on the outer edge of each page.

General Wiring Concerns for All Modules

Do not remotely ground any part of t he input sensor wiring. Remote grounds c onnec ted to the return term inal c ould m ak e the syst em oper ate incorrectly or damage the equipment. The signal r eturn is not true earth ground. It is an elect r onic r eferenc e point necessary to int er pr et t he sensor pr oper ly .

It is recommended that you r un input wiring in a conduit separate from AC power or output wiring and avoid long wiring runs .

For reliable input operat ion, follow these input wiring guidelines :

Never lay wires across the surfac e of a printed circuit board.

•

Wires should never be wit hin 1 in. or 25 mm of any com ponent on a printed

•

circuit board. Use shielded input wire.

•

Terminate the shield of the input wires at one end of the run only—preferably at

•

the end where your I/O module is located. Be careful when str ipping wir e not to drop small pieces of wire inside the cabinet.

•

Don’t run your input wiring in the same conduit with AC power.

•

Don’t run your input wiring in the same conduit with your output wiring.

•

Grounding the Modules

Each module includes a screw terminal connection for Earth ground. It is important that this connection be made as c los e to the module as pos s ible.

Caution Do not externall y ground any inpu t sign al connected to the module. This may damage the unit. Sign al return terminals are not connected to Earth Ground.

I/O Connecti ons

The actual input connections are locat ed on a twelve-position removable screw terminal connector located at the bottom of the module. Input wires s hould enter from either the top or bottom wiring tr oughs , and should c om e from the left side of the rack (by convention).

The inputs are labeled IN1, IN2, IN3, and so forth. Each pair of inputs is f ollowed by a connection labeled RET f or the input signal return, resulting in a sequence of IN1, IN2, RET, IN3, IN4, RET, and so on. For any given input, you should use the closest ret ur n terminal either bef or e or aft er that input—the next return terminal goes with the next two inputs, and so on.

The twelve-posit ion c onnec tor allows for eight inputs and f our signal returns. The diagram below indicates wher e eac h input number is located in the term inal bloc k .

During configuration, the value of the Electrical Type att r ibute you select tells the controller how to int er pr et the reading from each input. Each Universal input is read every 100 milliseconds. This r eading is independent of the controller s c an time.

UI-8-10

Each input includes a low-pass filter after the pull-up form ed by a series r es is tor and a parallel capacitor. The resistor is utilized f or ov er-voltage protection in limit ing c ur r ent t o two protection diodes ( not shown). Note also that all input returns ar e c ombined and must be directly connect ed to earth ground. It is possible to have mor e than one input s har e a single return wire. K eep in m ind that the current through each input is approx im ately

0.3mA, so voltage drops oc c ur with long r uns of sm all gauge wir e.

Pull-up Referen ce Resistor Selection Switches

In some measuring instances it is desirable that there be no pull-up resistor. Instead of physically removing or c utting the resistor off the printed circuit board, the input module includes a pull-up resistor s elec tion switch (labeled Swdis in t he diagr am ) for each input position. This s witch allows you to select whether or not you want a pull-up res is tor in the circuit. A small 8-pos ition switch module is accessible f r om the front of the module when the door is opened.

These switch modules are com m only c alled “ DIP Switches” and require a small object such as the tip of a pen or a small screwdriver to operate them. Each switch position acts as a “slide switch”. Pr es s ing the rais ed s lide m ar k er to t he side mark ed “ on” closes or enables the switch. To open or dis able the switch position, press the s lide m ar k er over to the “off” side.

Input Voltage Range Selection Switches (UI-8-10-10V Only)

The UI-8-10-10V m odule allows y ou to choose from two input voltage ranges. S elec tion is accomplished by using a switch arrangement that is similar to the operation of the pullup resistor swit c hes. The Voltage Range switches allow you to select a range (0-5 V ) or (0-10 V) for each input.

The 0-5V range allows connections to signals that do not exceed 5. 00V . T he 0-10V range allows connection to signals up to 10.00V. In this mode the circuit actually us es the same input measuring circuit as the 0-5V range, however, it div ides the voltage present by two thereby limiting t he internal circuitry to 0-5V. When you r ead a 0- 10V input the actual reading will be 0-5V. You must adjust your readings for the higher range v ia formula.

Switching to 10V input s dramatically lowers the impedance of the input to

Never apply a voltage to a therm is tor—doing so alters the thermistor’s ac c ur ac y and reliability. In fact, it’s a good idea to replace any thermistor that has had any sort of voltage applied to it.

Maximum Wire Runs for Thermistors

To keep thermistor er r or s minimal, limit the length of wire runs to the maximum for the gauge wire you select.

The following two pages include three tables that indicate the maximum length runs for wires of various gauges to keep errors within certain temper ature limits when using thermistor elem ents.

Voltage Dividers

There are instances when it is nec es s ar y to interface to a voltage source that is higher than the input range of the m odule. In these cases a voltage divider is necessar y .

DC input Voltage Divider

Two resistor values set up a ratio of voltage drop. These resistors m ust be sized appropriately (value and wat tage) for the source being monit or ed. The higher the resistance values, the less loading effect there will be on the source.

The circuit shown abov e is a simple two-resistor voltage divider c onnec ted to one of the UI-8-10 module’s inputs . The input circuitry of the module can m eas ur e a maximum of either 5 Volts or 10 Volts (UI - 8- 10- 10V only ) . T her efore, the voltage measured across Rinput must not exceed t his maximum .

In this case, be sure to switch the pull-up resistor out of the circuit .

ADJUST

The analog signal generated by t he m odule is c ontrolled manually by adjusting the A DJ US T pot entiometer below to the manual override switch. Programs have no effect on the output when the switch is in this position.

The output is disconnect ed. Programs and the setting on the ADJUST potentiomet er hav e no eff ec t on t he output Dev ic e when the switch is in this position.

The analog signal is generated as a dir ec t result of program control. The setting on the ADJUST potentiometer has no effec t on the output Device when the switch is in this position.

This is a variable cont r ol that allows y ou to manually adjus t the output of the analog signal when the ov er r ide s witch is in the MANUAL position. Insert the tip of a small screwdriver to use this control. Tur ning to the right (clockwise) increases the out put. Turning left (c ounterclockwise) decreases t he output.

DO-4-R

The DO-4-R, Continuum’s digital output module, has four Form C relay outputs, rated at 5 amps, 240 VAC. These versatile out puts make the DO-4-R an excellent choic e for switching motor star ters and other inductive loads up t o 240 VAC, with either two position (on/off) or pulse-width modulation (PWM) cont r ol. T he PWM featur e per m its the modulation of valves and dam per s to 0.1 second resolution. Two adjacent Form C relay outputs can be combined in s oft war e to provide a Tri-state output, for bi- dir ec tional control of valves and dam per s and other end dev ic es . Metal oxide varistors and 5000V isolation on each output ens ur e r eliable nois e- free operation.

A DO-4-R-O model with full over r ide c apabilities is also available. Each output has a local hand-off-auto s witch, which enables service personnel to override the output. The switch also provides override f eedbac k of output values for use in troubleshooting or test conditions. A local indic ator light for each output dis play s r elay status. Another LED provides override st atus.
