Description

Product Description

The IC200MDD840 is a hybrid discrete I/O module from GE Fanuc (Emerson) designed for the VersaMax platform. It integrates both digital inputs and relay outputs within a single module, allowing efficient handling of sensing and control tasks in compact automation systems.

This module combines 24 VDC sourcing inputs with electromechanical relay outputs, making it adaptable to both low-voltage control signals and higher-voltage load switching. It is commonly used in machine control panels where space optimization and wiring simplification are required.

I/O Configuration Overview

• Total I/O channels: 32

• Digital inputs: 20 channels

• Relay outputs: 12 channels (Form A, normally open)

The mixed configuration reduces the need for separate input and output modules, simplifying system design and reducing installation footprint.

Input Characteristics

• Input type: Positive logic (sourcing)

• Nominal voltage: 24 VDC

• Operating range: 0 to 30 VDC

• Input current (ON state): 2.0 to 5.5 mA

• Input current (OFF state): up to 0.5 mA

• Input impedance: ≤10 kΩ

• Response time:

• ON: 0.5 ms typical

• OFF: 10 ms typical

These characteristics ensure reliable signal detection from sensors such as proximity switches, pushbuttons, and limit switches.

Output Characteristics

• Output type: Relay contacts (Form A, normally open)

• Number of outputs: 12

• Contact ratings:

• 2 A at 5–265 VAC (resistive load)

• 2 A at 5–30 VDC (resistive load)

• 0.2 A at 31–125 VDC

• Minimum switching load: 10 mA

• Output grouping:

• Two isolated groups of 6 outputs each (typical design architecture)

Note: External protection devices (such as snubbers or fuses) are recommended for inductive loads.

Electrical Requirements

• Backplane current draw: up to 375 mA at 5 VDC

• External supply range:

• 0–125 VDC (nominal 5 / 24 / 125 VDC)

• 0–265 VAC (47–63 Hz, nominal 120 / 240 VAC)

Diagnostics and Indicators

• Individual LED indicators for each input and output point

• Dedicated module status LED (OK indicator)

These indicators provide immediate visual feedback for commissioning and troubleshooting.

Mechanical Specifications

• Dimensions: 110 × 66.8 × 50 mm

• Weight: 0.35 lb

• Mounting: Compatible with VersaMax carrier bases (IC200CHS series)

Environmental Conditions

FAQ

Q: Can this module drive inductive loads such as solenoids?
A: Yes, but external suppression components (e.g., RC snubbers or flyback diodes) are recommended to protect relay contacts.

Q: Are the outputs electrically isolated?
A: The relay contacts provide isolation from the control electronics, and outputs are typically grouped for load segmentation.

Q: Does the module require a separate power supply for outputs?
A: Yes. External power must be supplied according to the load voltage requirements.
