GE IC200ALG331-JD Analog Output Module

Product Overview

The GE IC200ALG331-JD is a 4-channel analog output module from the VersaMax series. It converts digital signals from a PLC or Network Interface Unit (NIU) into precise voltage or current outputs. This module supports both ±10 VDC voltage and 0–20 mA or 4–20 mA current signals with 16-bit resolution, ensuring highly accurate control of field devices. Moreover, its fast 7 ms update rate allows seamless real-time operation in demanding industrial environments.

Key Features & Benefits

• Four individually isolated analog output channels to prevent interference.

• Configurable default output state: maintain last value or preset state on fault.

• High-resolution 16-bit digital-to-analog conversion for precise signal control.

• Channel-to-channel and channel-to-backplane isolation enhances system reliability.
