GE IC200MDL744C VersaMax Discrete Output Module

Configured for high-density discrete output execution in GE VersaMax PLC platforms, the GE IC200MDL744C (IC200MDL744 Discrete Output Module) provides direct physical/electrical execution. This module manages 32 discrete sinking-type output channels organized into 2 groups, switching loads across 5 VDC TTL or 12/24 VDC operating ranges based on commands from the central processor.

Hardware Specifications

Backplane Bus Communication Velocity & Network Integrity

The IC200MDL744C communicates across the VersaMax backplane bus drawing up to 140 mA at 5 VDC to maintain high-speed I/O scan synchronization. Backplane bus driver circuits process output command packets with deterministic execution, delivering 0.2 msec turn-on and 1.0 msec turn-off switching response times. Firmware flash compatibility within the host CPU or Network Interface Unit (NIU) ensures error-free framing across the backplane, suppressing communication frame timeouts and logic bus drops during high-density I/O scan updates.

Frequently Asked Questions

Q: Does the IC200MDL744C include internal electronic fusing or replaceable fuse protection for individual channels?

A: No, the module contains no internal fusing. External fusing must be installed in series with field wiring to protect individual output circuits against overcurrent and short-circuit conditions.

Q: What external protective components are required when switching inductive field loads?

A: An external suppression circuit, such as a flyback diode for DC loads or a snubber network, must be wired directly across inductive loads to suppress voltage transients during turn-off.

Field Installation Guidelines

1. Completely de-energize the backplane power supply and external 12/24 VDC field power sources prior to mounting or removing the module.
2. Align the IC200MDL744C module with the VersaMax I/O carrier and press firmly until the module latches securely to the backplane base.
3. Wire field output loads to the carrier terminal strip, ensuring separate DC+ and DC- power connections are provided for each of the two 16-point groups.
4. Route field output wiring separately from high-voltage AC lines to minimize electromagnetic noise coupling.
5. Apply backplane and field power, then verify that the "OK" (backplane power) and "FLD PWR" (field power) green status LEDs illuminate steady ON before putting outputs into service.
