GE IC200MDD844 VersaMax Discrete Mixed I/O Module

GE IC200MDD844 Discrete Mixed I/O Module for VersaMax Systems

Product Introduction

The IC200MDD844 discrete mixed I/O module comes from GE Fanuc Automation. It belongs to the VersaMax product series and provides up to 32 I/O points. Specifically, the module divides these points into one group of 16 outputs and two groups of 8 inputs each.

Many industrial control systems need a flexible module that handles both sourcing outputs and standard inputs. The IC200MDD844 meets this need with its mixed design. All output points use sourcing or positive logic types. This means the outputs supply DC voltage directly to connected loads. Meanwhile, the input points use positive logic and draw current from attached devices before returning it to the common wire. As a result, the module suits a wide range of field wiring configurations.

Technical Specifications

The table below presents the main technical data for the IC200MDD844 module.

The IC200MDD844 supports negative logic with 12 V output. However, this feature requires an upgrade to the IC200MDD844C version or a newer release. Therefore, users should confirm their logic requirements before ordering. Besides, the module consumes 70 mA from a 5 V backplane power source. Each output point handles 0.5 A at 30 V.

Input Filter and Response Features

The IC200MDD844 offers a basic input on/off response time of 0.5 milliseconds. This fast response suits many high-speed control tasks. However, some environments suffer from switch contact bouncing or excessive electrical interference. For these situations, the module supports additional input filters.

Specifically, users can select filter times of 0, 1, or 7 milliseconds. The default filter time is 1 millisecond. A longer filter reduces false triggering caused by noise. Meanwhile, a shorter filter preserves fast response for time-critical signals. Consequently, engineers can tune the module to match their specific application needs. This flexibility improves measurement accuracy and system stability.

Mechanical and Environmental Parameters

The IC200MDD844 follows the standard VersaMax form factor. It mounts on a DIN rail inside a control cabinet. The compact housing fits tight panel layouts and saves valuable space. Additionally, the module draws logic power from the backplane. External output devices need a separate field supply.

The input voltage range spans 0 to 30 V. Meanwhile, the output voltage range covers 10.2 to 30 V. These wide ranges accommodate common industrial power levels. Proper grounding and shielding reduce electrical noise. Besides, adequate airflow around the module maintains stable thermal performance. Keep the cabinet within recommended temperature and humidity limits for best results.

Installation Guide

First, turn off all power before mounting the IC200MDD844 module. Next, align the unit with the VersaMax backplane connector. Then, slide it firmly into position until it locks. After that, connect the field wiring to the correct terminals. Remember that one group holds 16 outputs and two groups hold 8 inputs each.

Furthermore, select the appropriate input filter setting for your application. Use the default 1 millisecond filter for general-purpose signals. Meanwhile, choose the 7 millisecond filter in noisy environments. Finally, apply power and verify the LED indicators. Confirm that each input and output responds correctly before full operation.
