GE IC200ALG262 – VersaMax 15‑Bit Differential Current Input Module (8 Channels)

In stock

Product Introduction:

The IC200ALG262 is a high‑sensitivity analog input module from the GE VersaMax I/O series (now Emerson Automation). It is designed for precise acquisition of low‑level differential current signals in electrically noisy industrial environments. The module converts 0–20mA or 4–20mA analog signals from field sensors into 15‑bit digital data for the PLC, delivering high accuracy and strong noise rejection for demanding process control applications.
