Hardware/Software
Compatibility
The module and the applications described in this manual are compatible with
the firmware versions and software releases shown in Table 2.
Thermocouple Types The 1732E-IT4IM12R module supports the following thermocouples.
Cold Junction Compensation
When using thermocouples, cold junction compensation is required at the
termination of the thermocouple wire. The actual cold junction is outside of
the module at the CJC wiring block. The external thermistor provides the
reference temperature of the cold junction.
Accomplish a cold junction in the following ways:
• Enter an estimated temperature (Cold Junction Compensation Offset).
• Use external cold junction compensators to measure the cold junction
temperature directly.
To compensate for cold junction the 1732E-IT4IM12R thermocouple module
has to determine the actual cold junction temperature. If the module is
configured to provide cold junction compensation, then the user must use a
CJC Terminal Chamber, such as Allen-Bradley 871A-TS4CJC-DM or 871A-
TR4CJC-DM(1) as shown in the next diagram.

(1) The Allen-Bradley 871A-TS4CJC-DM or 871A-TR4CJC-DM terminal chamber has an
embedded thermistor, which facilitates thermocouple-based temperature measurement.
The thermistor types supported are Thermometrics MF65F302V/W, or DC95F302V/W.

10 Rockwell Automation Publication 1732E-UM004B-EN-P - October 2021
Chapter 1 Overview of the ArmorBlock Thermocouple and RTD Input Modules
Use an external thermistor to deduce the cold junction temperature to
accurately compensate the hot junction measured temperature.
The compensation voltage to be applied can also be estimated by applying
fixed cold junction correction using a fixed offset directly through the Studio
5000 Logix Designer application. The module supports hardware CJC from
0…70 °C.
The Thermocouple module also supports CJC error detection if a channel CJC
module is selected but is not correctly connected to the correct channel. The
module detects the open circuit condition and triggers the warning status bit
and fault LED.
Cold junction compensation is supported on all four channels of the
1732E-IT4IM12R module.
RTD Sensor Types The 1732E-IR4IM12R module supports 100 Ω -200 Ωα = 0.00385/0.003916 Pt
RTDs, 100/120
Ω Ni RTDs, and a 10 Ω Cu α =0.00427 RTD.
It supports 2-wire to 4-wire RTD. The following RTD input types are
supported.
The module uses lead wire compensation wire to measure and correct for any
cable lead resistance. The compensation circuit depends on an outside module
jumper to connect the third wire if the compensating lead wire is not available
(that is, if a 2-wire RTD is connected to the I/O connector).
