IC693TCM302

Overview

The IC693TCM302 is a Temperature Control Module (TCM) for GE Fanuc Series 90-30 PLCs, supporting precise temperature monitoring and control.

Inputs

• Channels: 8 thermocouple channels (J, K, or L) + 1 RTD compensation or external reference

• Resolution: 12 bits / 0.2°C

• Accuracy: ±1°C with auto-calibration

• Common Mode Voltage: ±12 V

• Fault Detection: Open thermocouple, reverse connection, out-of-tolerance readings

Diagnostics

• Power-on self-test (POST) for memory and peripherals

• Continuous monitoring of external power with LED indication

• Thermocouple condition checks per zone, reporting open-circuit or reverse polarity

• Zone controller response: maintain fixed duty cycle or turn off output on fault

• Reports thermocouple error status per zone
