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.

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).

The channel overrange alarm is set if the input is greater than the maximum
range selected – thermocouple or RTD range dependent.
Input Underrange Alarm
The input channel underrange alarm is set if the input is less than the
minimum temperature – thermocouple or RTD range dependent.
Process Alarms
The following process alarms are available.
•Low
• Low-Low
•High
•High-High
When the channel input goes below a low alarm or above a high alarm, a bit is
set in the data table. All Alarm Status bits can be read individually or by reading
the Channel Status Byte (see page 41).
You can configure the channel alarm set point individually for each channel.
Digital Filters The modules also support a digital low-pass filter to smooth input data noise
transients on each input channel. This value specifies the time constant for a
digital first order or low-pass lag filter on the input. It is specified in units of
milliseconds. A digital filter value of 0disables the filter.
To learn how to configure digital filters, see page 24.
IMPORTANT Open-wire detection is not supported for 1732E analog modules with analog
differential input.

Chapter 2
Install Your ArmorBlock I/O Module
Overview This chapter shows you how to install and wire the ArmorBlock EtherNet/IP
Dual Port 4-Point Thermocouple and RTD Input modules. The only tools you
require are a flat or Phillips head screwdriver and drill.
Install the Module To install the module:
• Set the network address
•Mountthemodule
• Connect the I/O, Network, and Auxiliary cables to the module.
Set the Network Address
The I/O block ships with the rotary switches set to 999 and DHCP enabled. To
change the network address, you can do one of the following:
• adjust the node address switches on the front of the module.
• use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation® BootP/DHCP.
• retrieve the IP address from nonvolatile memory.
The I/O block reads the switches first to determine if the switches are set to a
valid number. To set the network address:
1. Remove power.
2. Remove the switch dust caps.
3. Rotate the three (3) switches on the front of the module using a small
blade screwdriver.
4. Line up the small notch on the switch with the number setting you wish
to use.
Valid settings range from 001…254.
5. Replace switch dust caps. Make sure not to over tighten.
6. Reapply power.
7. Record IP address on product label found on the side of enclosure.

Chapter 2 Install Your ArmorBlock I/O Module
Set Network Address
When the switches are set to a valid number, the I/O block’s IP address is
192.168.1.xxx, where xxx represents the number set on the switches. The I/O
block’s subnet mask is 255.255.255.0 and default gateway address is set to
192.168.1.1.
When the I/O block uses the network address set on the switches, the I/O block
does not have a host name assigned to it or use any Domain Name Server.
If the switches are set to an invalid number (for example, 000 or a value greater
than 254 excluding 888), the I/O block checks to see if DHCP is enabled. If
DHCP is enabled, the I/O block asks for an address from a DHCP server. The
DHCP server also assigns other Transport Control Protocol (TCP) parameters.
(The modules are shipped with the network switches set to 999.)
If DHCP is not enabled, the I/O block uses the IP address (along with other
TCP configurable parameters) stored in nonvolatile memory.
Network Address Switch value 001
The module IP address cannot be the same as the gateway address. If the
address switches are set to 001, the module IP address becomes 192.168.1.1,
which is the same as the default gateway address. In this case, the module
gateway address will be set to 0.0.0.0.
Default Factory Configuration
The switch value 888 resets the module to default factory configuration on
power up. The module will not operate properly when powered up with this
setting. The switches must be set to a different (and valid) value and then
power cycled after a reset.
While in reset state, the module LED flashes red and the network LED goes off.
Enable or Disable the Web Server
With firmware revision 1.013 or later, the web server feature is disabled by
default. Use the network address switches to enable or disable the web server
for your application.
Value Description
000 Enables the web server. Cycle power to the module for the setting to take effect. When you apply power, the module LED flashes
red to indicate that the web server is enabled.
901 Disables the web server. Cycle power to the module for the setting to take effect. When you apply power, the module LED flashes
red to indicate that the web server is disabled.

For steps to enable or disable the web server, see Enable or Disable the Web
Server on page 57.
Mount the Module To mount the module on a wall or panel, use the screw holes provided in the
module. Refer to the drilling dimensions illustration to guide you in mounting
the module.
Mounting Dimensions
Install the mounting base as follows:
1. Lay out the required points as shown above in the drilling dimension drawing.
2. Drill the necessary holes for #6 (M3) pan head screws.
IMPORTANT For modules in field ControlFLASH™, the module does not disable the web
server by default. You need to Factory reset the module in order for the
web server to be disabled by default.
IMPORTANT To reduce the likelihood of exploitation and associated security risk, we
recommend that you keep the web server disabled.

Power Connectors
Attach an M12 cordset to the micro-style 4-pin M12 connector as shown below.
Micro-style 4-Pin Input Male Receptacle (Front view)
The power required by the module is based on a 4-pin micro-style connector
system. Power can be daisy chained through the module either left to right or
right to left. The standard configuration is with Module/Auxiliary power
entering the module on the left connector.
Both modules require two 24V DC (nominal) supplies. These supplies are called
the Module Power and the Auxiliary Power. The Module power supplies the
microprocessor, Ethernet, and the module I/O, while Auxiliary power is
daisychained through the module.
IMPORTANT Use the 1585D–M4DC–H: Polyamide small body unshielded mating
connectors for the D-Code M12 female network connector.
Note that the distance between the center of each Ethernet connector is
16.2 mm (see Mounting Dimensions on page 15). Rockwell Automation
recommends the use of suitable cable based on this measurement. Some
of the recommended cables are 1585D-M4TBJM-x and 1585D-M4TBDM-x
for daisychains.
IMPORTANT Use two twisted pair CAT5E UTP or STP cables.
