Description
Product Description
The IC200ALG321 by GE Fanuc / Emerson is a 4-channel analog output module engineered for the VersaMax PLC system. It delivers precise 0–10.24 VDC signals with 12-bit resolution, enabling control of actuators, valves, VFDs, dampers, and other analog-driven process devices.
This module is designed for industrial reliability, with robust isolation between the user-side outputs and the PLC logic, fast 0.3 ms update rate, and built-in diagnostics for detecting field-side power loss. Two front-panel LEDs indicate field power presence (FLD PWR) and backplane status (OK), ensuring clear visual monitoring of operational status.
The module requires an external 18–30 VDC supply for output circuitry, while the logic power is fully supported from the VersaMax backplane.
