Analog Input, 16 Bit Thermocouple, 7 Channels
Installation Instructions
The preferred installation technique is to mount the Thermocouple Module on a VersaMax
Connector-style I/O Carrier (IC200CHS003) and connect thermocouples to an Interposing
Thermocouple I/O Terminals (IC200CHS014). The Interposing Thermocouple-style I/O
Carrier provides both box-style wiring terminals and a built-in thermistor for Local Cold
Junction Compensation. It connects to the Connector-Style Carrier via cable as shown
below. This allows the thermocouple connections to be located away from the I/O modules
in the system.
However, it is also possible to mount the Thermocouple Module on one of the terminal-
style carriers (box-style, spring-style, compact-style, or barrier-style) and provide Local
Cold Junction Compensation by using a kit that includes the correct type of thermistor
(IC690ACC905). Both methods are shown below. The thermistor kit must be installed on
the A9 and A10 terminals of the carrier.
If the module will only be used to measure millivolt inputs, not thermocouple inputs, it can
be mounted on any type of I/O Carrier. The thermistor terminals A9 and A10 cannot be
used as millivolt input terminals.
