Instructions
Precautions
WARNING! All wiring must be performed by a qualified electrician or
instrumentation engineer. See diagram for terminal designations and
wiring examples. Consult factory for assistance.
WARNING! Avoid shock hazards! Turn signal input, output, and
power off before connecting or disconnecting wiring, or removing
or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un électricien
ou ingénieur en instrumentation qualifié. Voir le diagramme pour
désignations des bornes et des exemples de câblage. Consulter
l'usine pour assistance.
ATTENTION! Éviter les risques de choc! Fermez le signal d'entrée,
le signal de sortie et l'alimentation électrique avant de connecter ou
de déconnecter le câblage, ou de retirer ou d'installer le module.

ing nickel, which are known to the State of California to cause

Electrical Connections
This module is factory configured. See the model/serial number
label for T/C input type, range, output types & ranges, and options.
*
Do not make any connections to unused terminals or use them
as wiring junctions for external devices. This may cause permanent
damage to the module!
See wiring diagram at right. The T/C input must match the type
indicated on the model/serial number label. Use thermocouple
extension wire that matches your T/C type as needed.
Channel 1 and 2 output types and ranges are indicated on the
model/serial number label. Milliamp outputs may be wired for sink-
ing or sourcing. Sourcing provides 20 VDC power to your device.
Module Power
See model/serial number label to make sure available power
matches module operating voltage. The power supply is fuse
protected and the unit may be returned to us for fuse replacement.
For DC power, either polarity is acceptable, but for consistency,
wire positive (+) to terminal 25 and negative (–) to terminal 28.
Mounting to a DIN Rail
Install module vertically on a 35 mm DIN rail in a protective enclo-
sure away from heat sources. Do not block air flow. Allow 1" (25
mm) above and below housing vents for air circulation.
1. Tilt front of module down and position the
lower spring clips against the bottom edge of
DIN rail.
2. Push front of module upward until upper
mount snaps into place.
Removal
Avoid shock hazards! Turn signal input, out-
puts, and power off.
1. Push up on bottom back of module.
2. Tilt front of module downward to release
upper mount from top edge of DIN rail.
3. Remove module from the DIN rail.
Calibration
Input and output ranges are factory pre-configured (at 24°C ±1°C).
Zero and Span potentiometers can be used to calibrate each output
channel as required.
1. It will be necessary to simulate or create a low and a high tem-
perature input to the module and use an accurate measurement
device to calibrate each output.
2. Apply power to the module. Allow 20 minutes for warm up time and
ensure the module is at a stable temperature during calibration.
3. Set the input to your minimum value for the Zero calibration.
4. Using an accurate measurement device for each output, adjust
the Zero potentiometers for the exact minimum outputs desired.
This will produce the corresponding minimum output signals.
For example: 4 mA for a 4-20 mA output or –10 V for a ±10
V output. The Zero controls should only be adjusted when the
input signal is at its minimum.
5. Next, set the input at maximum, then adjust the Span pots
for the exact maximum outputs desired. This will produce the
corresponding maximum output signals. Example: for 4-20 mA
output, the Span control will provide adjustment for the 20 mA
or high end of the signal. The Span controls should only be
adjusted when the input signal is at its maximum.
6. Repeat adjustments for maximum accuracy. You may also be
able to fine-tune the outputs by adjusting the calibration of the
devices you have connected to the module outputs.

Optional Alarm Relay
See model/serial number label for the factory configured relay
option codes, if equipped. A red/green bi-color LED indicates the
alarm state. It will be green during a non-alarm condition and red
during an alarm condition.
High Alarm (H): The alarm relay changes state when the temperature
exceeds the trip point. The relay resets when the temperature drops below
the reset point. For a high alarm, the trip point is above the reset point.
Low Alarm (L): The alarm relay changes state when the temperature goes
below the trip point. The relay resets when the temperature exceeds the
reset point. For a low alarm the trip point is below the reset point.
HT: Latching alarm with push button reset.
HP: Latching alarm with power-off reset. Module power must be
turned off to reset alarm.
RA: Reverse-acting alarm. Relay coils energized in an alarm condi-
tion. No alarm condition with module power off.
Relay Terminals
See diagram for alarm contact wiring. The module does not provide
power to the relay contacts. Use an appropriate RC snubber for
inductive loads (motors, solenoids, contactors) to ensure good
relay contact life.
The dual DPST contact sets are in a Form A (NO) and a Form B (NC)
configuration and operate in unison with a single setpoint. They
may be field wired for Form C operation as required.
Set Point Adjustment
This multi-turn potentiometer allows adjustment of the alarm trip
point. This control is adjustable from 0 to 100% of the input range.
Reset Point Adjustment
This multi-turn potentiometer allows adjustment of the alarm reset
point. This control is adjustable from 0 to 100% of the input range.
Sufficient deadband (difference between trip and reset point) should
be used to prevent chattering of the relays or false trips when the
input is unstable or changes rapidly.
Alarm Adjustments
Set the input signal to a level that represents the desired set point.
Adjust the Set Point potentiometer to the point at which the relay
changes state from a non-alarm to an alarm condition.
Set the input signal to a level that represents the desired reset point.
Adjust the Reset Point potentiometer to the point at which the relay
changes state from an alarm to an non-alarm condition.
Operate the signal source through the set and reset points to con-
firm desired operation and adjust if necessary.
Relay Test Function
This can be used as a diagnostic aid during initial start-up or
troubleshooting, or as a manual over-ride function. When the front
Relay Test button is depressed or terminals 11 and 12 closed, it
will drive the relay and the bi-color alarm LED to their opposite
Upper Mount
states. When released, the relay and LED will return to their prior
states. The Relay Test button also resets the relay on models with
the HT option.
Spring Clips
Output Test 1, Output Test 2
This can be used as a diagnostic aid during initial start-up or
troubleshooting, or as a manual over-ride function. When the Test 1
or Test 2 buttons are depressed or terminals 9 & 12 or 10 & 12 are
closed, it will drive the DC output for that channel to 75% of span or
a customer-specified value set at the factory. When released or the
contact(s) opened, the output(s) will return to their normal levels.
Operation
The module accepts a thermocouple input and provides two DC
outputs that are linearized to thermocouple input temperature.
The green LoopTracker
®
sensed by the module. The red LoopTracker LEDs vary in intensity
with changes in the DC output signals. If any LED fails to illuminate,
or fails to change in intensity as the process changes, check the
module power or signal wiring. Note that it may be difficult to see
the LEDs under bright lighting conditions.
Yellow LED Functions
The yellow status LED provides a visual indication of operational modes.
Normal operation:
Off
Output Push-to-Test: On for Test 1 or Test 2
Operational error:
Blinking 2 digit code
If an error occurs during operation, the yellow Status LED blinks an
error code. Check sensor, wiring, or consult factory.
