GE IC670ALG230C

GE Fanuc IC670ALG230C is an analog current input module from the GE Fanuc Field Control (Genius I/O) series. It is designed to acquire industrial field current signals and convert them into digital values for PLC or control system processing. The module is commonly used in process control, factory automation, and distributed I/O applications.

1. Product Overview

The IC670ALG230C provides 8-channel analog current inputs for connecting transmitters, sensors, and other current-output field devices. It accepts standard industrial current signals such as 0–20 mA and 4–20 mA (depending on configuration), converting the analog input values into 12-bit digital data for the host controller.

The module belongs to the GE Fanuc Field Control I/O family, which uses a Bus Interface Unit (BIU) to communicate with the host PLC and manage distributed I/O modules.
