Brief Product Description

GE HE693RTD600 is a 6-channel RTD temperature input module developed by Horner APG for GE Fanuc Series 90-30 PLC rack system. It directly connects multiple types of RTD thermal resistance sensors, converts resistance signals into digital temperature data for the PLC CPU, and eliminates the requirement for external signal transmitters. This module supports Pt100, Pt1000, Cu, Ni multiple RTD types, compatible with 2-wire,3-wire sensor wiring modes, with built-in surge protection and channel isolation. It uses 16-bit high-precision A/D conversion, and transmits temperature data to the main CPU via the 90-30 backplane bus. Designed for continuous 24-hour temperature monitoring in industrial environments. Fully tested surplus and refurbished GE HE693RTD600 modules are available for legacy Series 90-30 PLC maintenance, temperature input card replacement and plant automation retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Temperature reading drifting or no value after installing HE693RTD600?
  A: Check RTD sensor and cable integrity, verify 2/3-wire wiring selection in PLC configuration, inspect terminal connections, check grounding and eliminate EMI interference.
• Q: Does GE HE693RTD600 support hot-swap replacement?
  A: Hot swap is not supported. Back up PLC program, power down Series 90-30 chassis and perform lockout-tagout before replacement to avoid loss of temperature data.
• Q: What PLC platform is HE693RTD600 for?
  A: It is a dedicated RTD temperature module for GE Fanuc Series 90-30 PLC system.
• Q: What RTD sensor types does this module support?
  A: It supports Pt100, Pt1000, copper Cu and nickel Ni series thermal resistance sensors.
• Q: Is GE HE693RTD600 available for new automation projects?
  A: This legacy Series 90-30 RTD input module is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing PLC system maintenance and retrofits.
