Description

Product Overview

The IC200MDD844 is a compact mixed-signal discrete I/O module developed for the GE VersaMax platform, integrating digital inputs and relay-style DC outputs within a single hardware unit. It is engineered to simplify system architecture by combining sensing and actuation functions, minimizing rack space and reducing field wiring complexity.

This module provides 32 total I/O points, split evenly between 16 DC inputs and 16 DC sourcing outputs. It is suitable for machine control systems where both input acquisition and output switching are required in a single distributed I/O node.

Hardware revision C and later versions introduce enhanced compatibility, including support for negative-logic inputs and 12 V output configurations.
