Description
Overview
The IC670ALG630 thermocouple input module is part of GE’s FANUC Field Control family and provides eight high‑accuracy temperature‑measurement channels for industrial automation systems. Designed for applications requiring precise thermal monitoring, the module supports a wide range of thermocouple types and offers flexible configuration for both direct millivolt acquisition and temperature‑scaled outputs.
Signal Processing and Measurement
Each channel incorporates cold‑junction compensation and open‑circuit detection to maintain measurement accuracy under varying environmental conditions. A solid‑state, optically isolated multiplexer feeds a 15‑bit plus sign‑bit A/D converter, enabling high‑resolution digitization of low‑level thermocouple signals.
When operating in millivolt mode, the IC670ALG630 provides resolution down to 0.01 mV, making it suitable for sensitive low‑voltage sensing tasks beyond standard thermocouple applications. An onboard microprocessor continuously evaluates channel health, detecting out‑of‑range conditions and sensor faults to support reliable system operation.
System Integration
The module integrates directly with GE’s Genius Bus architecture through compatible Bus Interface Units, ensuring efficient data exchange within distributed control systems. Its rugged construction and diagnostic capabilities make it well‑suited for process industries where temperature stability and measurement integrity are critical.
