General Electric IC660BBA021 RTD Input Module

The GE IC660BBA021 RTD Input Module is part of the GE Fanuc Genius I/O product line, specifically designed for reliable temperature monitoring using RTD (Resistance Temperature Detector) sensors in industrial environments. This module offers 6 RTD input channels, enabling accurate, real-time temperature acquisition for process control systems.

What distinguishes the IC660BBA021 is its ability to directly interface with RTDs—particularly 100-ohm platinum sensors (Pt100)—without the need for additional signal conditioning hardware. The module provides highly accurate temperature readings over a broad operating range and features built-in diagnostics, channel-level isolation, and field-mountable rugged design. It integrates seamlessly into GE’s Genius I/O distributed control system, providing critical temperature data where reliability and durability are paramount.
