Product Short Description
Product Introduction
The GE HE693RTD660 is a 6-channel RTD (Resistance Temperature Detector) input module designed exclusively for GE Fanuc Series 90-30 PLC systems, serving as a core component for precise temperature measurement and monitoring in industrial automation. It converts resistance signals from RTD sensors (Pt100, Pt1000, Ni120, Cu10, TD5R Silicon) into digital values accessible via the PLC backplane, with on-board processing handling signal conditioning, linearization, and alarm logic without relying on the CPU. The module features 700 VDC bus isolation and 5 VAC channel-to-channel isolation to prevent ground loops and voltage transients, ensuring stable operation in harsh industrial environments. It supports programmable resolution down to 0.05°C, six dedicated %AI registers for temperature data, six %AQ registers for alarm setpoints, and 16 %I bits for alarm status indication. It integrates seamlessly with Series 90-30 carriers, requires no external signal conditioners, and delivers reliable, high-precision temperature data for process control and equipment protection applications.
