GE IC200MDL940J Relay Output Module

Configured for discrete output switching and electrical load driving in VersaMax system architecture, the GE IC200MDL940J (IC200MDL940 Discrete Output Module) provides direct physical/electrical execution. It interfaces controller logic signals with external field actuators, solenoids, and contactors across 16 channel-to-channel isolated Form A relay contacts.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Flash Compatibility

The module coordinates real-time relay state execution directly with the primary CPU across the local backplane bus. Signal processing registers handle contact driver timing to prevent backplane bus communication velocity degradation during simultaneous switching of all 16 channels. Firmware flash compatibility checks occur during system initialization to validate configuration parameters and preserve deterministic update rates across high-density I/O racks.

Frequently Asked Questions

Q: What is the maximum load current rating permitted per relay channel on this module?

A: Each isolated Form A relay channel supports a maximum output load current of 2.0 A across the full operating voltage range.

Q: Are the output channels electrically isolated from one another?

A: Yes, the module provides channel-to-channel isolation, allowing individual output points to switch independent power sources or voltage levels up to 265 VAC / 125 VDC.

Q: How much current does this module draw from the 5 VDC backplane power supply?

A: The module draws a maximum current of 490 mA from the 5 VDC backplane bus when all 16 output relays are energized simultaneously.

Field Installation Guidelines

1. Align the module housing with the designated I/O carrier slot on the VersaMax DIN-rail assembly and press firmly until the locking mechanisms click into place.
2. Route high-voltage AC or DC switching cables separately from low-voltage DC input wiring and communication buses in distinct wire troughs.
3. Terminate external load supply lines to the removable terminal block using copper wire rated for a minimum of 75 deg C operation.
4. Install inductive load suppression hardware (such as RC snubbers for AC loads or flyback diodes for DC loads) directly across external field actuators to suppress contact arcing and transient voltage spikes.
