GE IC670ALG230 – Genius Field Control 8-Channel 12-Bit Current Source Analog Input Module

In stock

Product Introduction:

The IC670ALG230, designed by GE Fanuc (now Emerson Automation), is a high-density current-source analog input module within the Genius Field Control I/O series. It interfaces with 2-wire, 3-wire, or 4-wire industrial sensors and transmitters, converting standard 0–20mA or 4–20mA current signals into 12-bit digital data for processing by a PLC or host controller via a Bus Interface Unit (BIU). Engineered for centralized, multi-channel signal acquisition in harsh industrial environments, it delivers reliable, high-resolution measurements for process monitoring and control.

Key Features
8-Channel High-Density Input: Consolidates 8 current inputs for efficient, space-saving signal collection.
Software-Configurable Ranges: Select 0–20mA or 4–20mA per channel via BIU or software, no hardware jumpers needed.
Fast 12-Bit Conversion: 60µs per channel ensures rapid, accurate data acquisition for dynamic processes.
Robust Diagnostics: Detects open wires (4–20mA), overrange, and circuit faults for proactive maintenance.
High Isolation: 1500VAC isolation blocks electrical noise and ground loops, safeguarding the control system.
Built-In Overcurrent Protection: 30mA max input and 1A fuse prevent damage from field-side electrical faults.
Wide Environmental Tolerance: Operates reliably in extreme temperatures and humidity for deployment in harsh industrial settings.
