GE Fanuc HE693RTD600 RTD Temperature Input Module

GE Fanuc HE693RTD600 is an RTD temperature acquisition module designed for GE Series 90‑30 PLC chassis. It receives resistance signals from RTD thermal resistance sensors, converts resistance variation into digital temperature values, and transmits processed data to the PLC CPU for equipment temperature monitoring and over‑temperature interlock protection.

This module supports multiple common RTD types, provides channel‑level fault diagnosis function for open‑circuit and short‑circuit detection. It adopts rack plug‑in installation, widely used as replacement spare parts for power, chemical and manufacturing automation control cabinet maintenance and retrofit projects.
