GENERAL DESCRIPTION

The IAMA – Universal Signal Conditioning Module Series can isolate and
convert over 100 combinations of analog signal ranges. The IAMA3535
converts and transmits signals linearly proportional to the input, while the
IAMA6262 transmits the scaled square root of the input signal. This allows the
IAMA6262 to provide a signal that is linear to flow rate in applications utilizing
a differential pressure transducer.

DIP switch range selection eliminates the need to order and stock different
modules for each input and output signal range, and allows quick and
convenient setup for over 100 standard signal conversions. By utilizing the
Field mode of calibration, the user can customize the input and output scaling
for odd applications, including reversal of the output relative to the input.

In addition to the conversion capabilities, the IAMA modules feature
optically isolated Input/Output signal circuits and transformer isolated Power to
Input, Power to Output circuits.

The modules’ overall full scale accuracy typically exceed 0.05% depending
upon range selection and scaling. The microprocessor based design provides
ease of field scaling and the onboard E2PROM stores scaling values for future
recall. Both models come factory precalibrated for all input and output ranges.
Factory or custom field scaling can be selected by a simple mode switch change.
The IAMA can be factory recalibrated in the field if desired.

The modules’ environmental operating temperature range is -20°C to +65°C.
DIN rail mounting saves time and panel space. The units are equipped with
universal mounting feet for attachment to standard DIN style rails, including top
hat profile rail according to EN50022 - 35x7.5 and 35 x 15 and G profile rail
according to EN50035-G32.

IAMA is received from the factory. Therefore, until the IAMA is field scaled,
factory and field modes perform identically. See SCALING PROCEDURE for
detailed instructions on field programming the IAMA.

The units can be scaled to any minimum scale and full scale values within the
extent of the selected range. The closer together the minimum and full scale
values are to each other, the less accurate the signal will be. For example, if the
0 to 1 V input range is selected, and the unit is scaled for 0 to 0.5 V, the signal
has the same resolution as the 0 to 1 V range. Since this resolution will be two
times the percentage of span for 0.5 V, more accuracy can be achieved by using
the 0 to 0.5 V range.

The input may exceed the full scale value for the selected range by 10% of
span, but the IAMA will not update the output beyond 10% over range.

The red and green LED’s indicate the status of the modules during scaling and
normal operation. Table 1, LED Indications, details the LED indications for
various unit conditions.

The IAMA – Signal Conditioning Module Series is designed for use in
industrial environments. Suppressor diodes protect both input and output
circuits from wiring errors and transient high voltage conditions.

INPUTS

The IAMAs accept a full range of process signal inputs and isolate and
convert these signals to common industrial control signals. The input signal
combinations are configured by making specific DIP switch selections on the 10
position DIP switch.

MODULE ISOLATION

IAMA modules feature “3-Way” Signal Isolation. The 3-Way isolation is a
combination of optical and transformer isolation. The optical isolation provides
common mode voltage (CMV) isolation up to 1.5 kV between the sensor input
and the process signal output. The IAMA’s power is isolated from the sensor
signal input and the process signal output by a DC/DC transformer isolation
circuit.

OVERVIEW

The IAMA3535 continuously monitors a voltage or current input and
provides a linearly proportional voltage or current output, while the IAMA6262
transmits the scaled square root of the input signal. This allows the IAMA6262
to provide a signal that is linear to flow rate in applications utilizing a
differential pressure transducer. Both units have two modes of operation known
as Factory and Field modes. Factory mode is used when the default input and
output ranges are suitable. Field mode can be independently selected for both
the input and output, and allows the user to custom calibrate, or scale the signal.
If Factory mode is selected, the IAMAs use factory presets for the selected input
or output range. If Field mode is selected, the IAMAs can be custom scaled
within a selected input or output range. Field mode also allows the IAMA to
reverse its output in relation to its input.

The units are factory precalibrated for minimum and full scale for all input
and output ranges. The factory calibration values are permanently stored in
E2PROM and should not be changed in the field, unless unacceptable error or a
factory checksum error occurs. See Factory Recalibration for details. Field
scaling is achieved by applying minimum and full scale values from a
calibration source and storing the values by a single DIP switch transition. Field
scaling is available for all input and output ranges and the values are
permanently stored in E2PROM until reprogramming occurs.

After field scaling, the IAMAs can be changed between Factory and Field
modes for a particular range, which restores the respective setting. The Factory
and Field E2PROM locations contain the same calibration values when the

OUTPUTS

As with the input choices, the process signal output of the modules is DIP
switch selectable. A 1 position DIP switch is used to select between the 1 mA/20
mA output ranges. The maximum output current signal is 22 mA with ≤600 Ω
output resistance and the maximum output voltage signal is 11 V with ≥1 KΩ
output resistance.

ZERO AND SPAN

The input zero and span are set by first applying the minimum value then
transitioning S1-2 to store that value. Next, the full scale value is applied and the
DIP switch transition stores the value. The output scaling is performed in a
similar manner but the output is driven to the desired minimum and full scale
values by the calibration source applied to the input. S1-1 is used to store the
minimum and full scale output values.

The span is defined by: span = (full scale - minimum scale).

ILLEGAL RANGE SELECTIONS AND CHANGES

The ranges should only be selected before power is applied. If an invalid input
or output range is selected when power is applied the output is set to approximately
0 VDC and the red LED indicates the error according to Table 1. Power must be
removed and valid ranges selected for the IAMA to operate properly.

If S1 switches 3 through 10 are changed while the IAMA is operating, the red
LED indicates a range change according to Table 1, LED Indications and the
output goes to the previously stored range minimum scale value. Normal
operation will be resumed if the switches are placed back in the previous
positions or power is removed and restored.

CHECKSUM ERRORS

A checksum is performed every time power is applied to the IAMA. If a
checksum error occurs, the LEDs will indicate where the error occurred
according to Table 1, LED Indications. Operation with a checksum error is not
recommended but can be done in critical situations. If an error occurs,
re-calibration of the field or factory ranges to be used must be performed.

If a field checksum error occurs, the IAMA will operate only in factory mode.
If a factory checksum occurs, the IAMA will operate only in a previously
calibrated field mode. Do not perform a field scaling until the factory checksum is
cleared. Since a checksum error is a high priority LED indication, the LEDs will
indicate the error until it is cleared. This will exclude other LED information.

FIELD OR FACTORY MODE SELECTION

SELECTING FIELD MODE (2 Methods):

1. Scale the input or output according to SCALING PROCEDURE 2.0 or 4.0

2. Before applying power, set the input or output (or both) field/factory switch
to the up (field) position. Field calibration values will be restored upon
power-up. If the IAMA has not been previously field calibrated, the E2PROM
will contain the factory calibration values which will be restored.

SELECTING FACTORY MODE (2 Methods):

1. Before applying power to the IAMA set the input or output (or both) field/
factory switch to the down (factory) position. Factory calibration values will

be restored upon power-up.

2. While power is applied to the IAMA and it is operating in the field input and/
or output mode, set the desired field/factory switch(s) to the down (factory)
position. The factory calibration values will be restored.

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of

immunity to Electromagnetic Interference (EMI), proper installation and wiring
methods must be followed to ensure compatibility in each application. The type
of the electrical noise, source or coupling method into a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected
to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield connection
should be made as short as possible. The connection point for the shield
depends somewhat upon the application. Listed below are the recommended
methods of connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end where the

unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.

3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors, feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run through metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter. Also, Signal or Control cables within
an enclosure should be routed as far away as possible from contactors,
control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression
devices such as Ferrite Suppression Cores for signal and control cables is
effective. The following EMI suppression devices (or equivalent) are
recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize radiated
and conducted noise (EMI), some type of contact protection network is
normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid
state outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.
RLC part numbers: Snubber: SNUB0000
Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could affect the instrument’s operation.

relate to Red Lion Controls products.

WIRING CONNECTIONS

All conductors should meet voltage and current ratings for each terminal.

Also cabling should conform to appropriate standards of good installation, local
codes and regulations. It is recommended that power supplied to the unit be
protected by a fuse or circuit breaker. When wiring the unit, use the numbers on
the label to identify the position number with the proper function. Strip the wire,
leaving approximately 1/4" (6 mm) of bare wire exposed. Insert the wire into
the terminal, and tighten the screw until the wire is clamped tightly.
