GE IC693TCM302 Temperature Control Modules
Programmable ControllersThe Temperature Control Module (TCM), is a high performance control module providing
eight channels of thermocouple input and eight channels of control output in a single
RX3i module. Each channel can operate in closed or open loop mode relieving the PLC
of providing the temperature control functions. The module also supports Autotuning.

PACSystems RX3i Programmable Controllers
The Thermocouple Input Modules allow thermocouple temperature sensors to be directly
connected to the PLC with external signal processing (transducers, transmitters, etc.).
The module performs all analog and digital processing of the thermocouple signal. The
enhanced thermocouple input modules add isolation or high-resolution. On these modules,
each channel can be configured for a specific type of sensor wire. An autodetect external
AD592 cold junction compensation feature is also available.
