Product Short Description
Product Overview
GE HE693RTD600 is a dedicated 6-channel RTD (Resistance Temperature Detector) input module designed for the GE Fanuc Series 90-30 programmable logic controller (PLC) system. It directly interfaces with various RTD sensors to measure temperature, converts resistance signals to digital temperature values, and transmits data to the PLC’s %AI input table without external signal processing equipment. The module integrates 16-bit A/D conversion, automatic lead wire compensation (2/3/4-wire), cold junction compensation, and linearization, delivering precise and reliable temperature data for industrial control applications. It features robust isolation, built-in diagnostics, and flexible sensor compatibility, enabling seamless integration into Series 90-30 racks for diverse industrial temperature monitoring needs.
