The IC670ALG620 (Model: IC670ALG620) is a high-precision analog input module specifically designed for Resistance Temperature Detector (RTD) acquisition within the GE Fanuc Field Control I/O family. This module provides four independent channels capable of interfacing with 3-wire and 4-wire RTD sensors, converting low-level resistance signals into high-resolution digital data. The IC670ALG620 (Part Number: IC670ALG620) is engineered for critical thermal monitoring in industrial processes where temperature accuracy and sensor lead compensation are vital for system stability.
Equipped with a 15-bit plus sign digital resolution, the IC670ALG620 (Model: IC670ALG620) ensures exceptional sensitivity to minute temperature fluctuations. It features comprehensive onboard diagnostics, including detection for open RTDs, short circuits, and out-of-range alarms. While some general documentation may list this series as having 8 channels for standard voltage/current, the IC670ALG620 variant is a dedicated 4-point RTD specialist, optimized for high noise rejection and thermal stability (E-E-A-T) in demanding substation and factory floor environments.
The IC670ALG620 (Part Number: IC670ALG620) offers robust signal conditioning with high-order hardware filtering.
