GE IC200MDD844 – VersaMax 32-Point Discrete Mixed I/O Module (16-In/16-Out)

In stock

Product Introduction: The IC200MDD844 is a high-density discrete mixed input/output module from General Electric’s VersaMax PLC series. Integrating 16 digital inputs and 16 digital outputs on a single unit, it delivers a space‑saving, cost‑effective solution for industrial automation systems that require balanced signal sensing and actuator control. Designed for 24VDC positive‑logic environments, it connects directly to standard sensors, switches, relays, and solenoids. With fast response, configurable filtering, and robust isolation, it ensures reliable operation in harsh electrical conditions and simplifies system design by reducing the number of modules and cabinet wiring.

Key Features

High‑Density Mixed I/O: 32 points (16In/16Out) reduce cabinet space, wiring, and system cost.
24VDC Positive‑Logic Compatibility: Works with standard industrial sensors, limit switches, proximity sensors, and 24VDC actuators.
Sourcing Outputs: Directly drives relays, solenoids, indicator lamps, and small motors without external pull‑up resistors.
Configurable Input Filters: Suppresses contact bounce and electrical noise with 0ms/1ms/7ms settings; default 1ms for stability.
Fast Response: 0.5ms base input speed supports high‑speed interlocks and sequence control.
LED Status Indicators: Individual LEDs for each input and output enable immediate visual diagnostics; module‑level OK and FLD PWR LEDs.
Surge and Noise Protection: Built‑in transient suppression and EMC compliance ensure stable operation in electrically noisy environments.
Hot‑Swappable: Can be replaced during system operation without shutting down the PLC.
Modular Expansion: Connects to other VersaMax I/O via high‑speed backplane; supports distributed I/O architectures.
