The GE Fanuc IC693TCM302B is a temperature control module designed for the Series 90-30 PLC platform. It provides multi-zone temperature regulation by processing thermocouple signals and controlling external heating equipment. With dedicated control functions, the module can manage temperature loops without requiring the main PLC CPU to perform every temperature-control calculation.
This module suits industrial processes that require consistent thermal conditions, reliable feedback, and coordinated control across multiple heating zones.

Specifications should be confirmed against the documentation for the exact hardware revision before installation.
The module can be used in industrial ovens, packaging machinery, plastics processing, heat-treatment equipment, and production lines requiring several independently controlled temperature zones.
Install the module in a compatible Series 90-30 rack and follow the approved wiring diagrams. Verify thermocouple polarity, field power requirements, output connections, and control parameters before commissioning.
For maintenance, inspect connectors, wiring, and status indicators regularly. If temperature readings fluctuate or outputs fail to respond, check the sensors, field supply, and configuration before replacing the module.
