Description
Product Description
The IC200ALG230 from GE Fanuc / Emerson is a 4-channel analog input module designed for the VersaMax PLC platform. It provides precise 12-bit measurement for industrial voltage or current signals and supports flexible single-ended input configurations, making it ideal for process monitoring, control, and automation tasks.
Channels can be independently set for voltage (±10 VDC default or 0–10 VDC selectable) or current mode (4–20 mA), allowing adaptation to a wide range of field devices. The module is powered entirely from the VersaMax backplane, requiring no external power, and includes LED indicators for backplane status (OK) and internally generated field power (INT PWR).
