GE Fanuc HE693THM166 Thermocouple Input Module
The GE Fanuc HE693THM166 is a high-density 16-channel thermocouple input module manufactured by Horner Automation for GE Fanuc Series 90-30 PLC systems. It provides direct interfacing between thermocouple sensors and the PLC backplane without external signal converters, enabling precise multi-point temperature acquisition for industrial process monitoring.
Signal Processing and Thermocouple Support
The module features 16 isolated thermocouple input channels supporting sensor types J, K, N, T, E, R, S, B, C, and X. Utilizing an integrating A/D conversion method with a rate of 40 channels per second, the module delivers a temperature resolution of 0.5 deg C (or 0.5 deg F) and a typical accuracy of ±0.5 deg C for standard J, K, N, and T types. Integrated open-circuit detection automatically identifies broken field sensor wires and reports fault alarms to the system controller.
System Integration and PLC Memory Mapping
Designed for Series 90-30 I/O rack mounting, the module maps field data into the PLC using 16 analog input words (%AI) and 16 discrete input bits (%I). Field wiring connects via a 32-position removable terminal block using recommended 24 AWG wire. Power is drawn directly from the backplane, consuming 100 mA at 5 VDC.
