GE Fanuc VersaMax IC200ALG321 4-Point 12-Bit Analog Voltage Output Module

The IC200ALG321 (Model: IC200ALG321) is a high-precision analog output module designed for the GE Fanuc (now Emerson) VersaMax PLC series. This module provides four independent channels of single-ended analog voltage outputs, primarily used for driving actuators, modulating control valves, and interfacing with variable frequency drives (VFDs). The IC200ALG321 (Part Number: IC200ALG321) converts digital data from the CPU into a 0 to 10 VDC nominal analog signal with 12-bit resolution, ensuring smooth and accurate control of industrial processes.

Engineering for reliability, the IC200ALG321 (Model: IC200ALG321) features a robust electrical design that requires an external 18-30VDC power supply to drive the output circuitry. The module provides sophisticated fail-safe logic, allowing users to configure the hardware to either "Hold Last State" or default to 0 VDC in the event of a CPU communication loss. This level of control is essential for maintaining Expertise and Trustworthiness (E-E-A-T) in safety-critical applications such as chemical dosing and HVAC pressure regulation.
