Description
Product Overview
The IC200MDD845 is a hybrid discrete I/O module designed for the GE VersaMax platform, integrating both input acquisition and relay output switching within a single compact unit. It is engineered to reduce rack space usage and simplify field wiring while maintaining flexible control capability for mixed signal applications.
This module combines 16 channels of 24 VDC digital inputs with 8 Form A relay outputs. Each output is independently isolated, enabling reliable switching of AC and DC loads in diverse industrial environments.
Depending on hardware revision (C or later), the input section can support both positive and negative logic configurations, improving compatibility with a wide range of field devices.
