Description

Product Description

The IC200ALG262 is a precision analog current input module designed for the GE Fanuc VersaMax PLC platform. It provides eight differential input channels optimized for current loop signals, ensuring stable and accurate measurement in electrically noisy industrial environments.

By using differential signal acquisition, this module significantly improves immunity to electromagnetic interference compared to single-ended designs. It is particularly well suited for applications where signal integrity is critical, such as process industries and power systems.

The module supports both 4–20 mA and 0–20 mA input ranges, selectable via hardware configuration. It integrates directly into VersaMax I/O stations and supports hot insertion, allowing replacement without powering down the system.
