GE IC693TCM302B Temperature Control Module

Overview

The GE IC693TCM302B is a Temperature Control Module designed for the Series 90-30 PLC family. It controls eight independent temperature zones with thermocouple or RTD inputs and relay outputs. The module operates in open-loop or closed-loop (PID) modes for flexible temperature regulation. The "B" revision improves resolution and extends the temperature range. It suits industrial applications such as ovens, kilns, and process heaters. The device includes diagnostic LEDs for power, run, fault, short, and each output channel. This helps quickly detect wiring or sensor issues. The module uses plug-in connectors with captive screw terminals for easy wiring.
