GE Fanuc IC200MDL742 VersaMax Discrete Output Module
The GE Fanuc IC200MDL742H, also cataloged as the IC200MDL742 Discrete Output Module, operates as a dedicated hardware component for driving discrete field actuators within GE Fanuc VersaMax PLC backplane networks. The module executes high-density switching by delivering 32 sourcing (positive logic) output channels operating at a nominal 24 VDC. Internal electronic protection and free-wheeling diodes buffer system logic against high-voltage inductive surges, while sub-millisecond response times maintain deterministic execution for real-time machine processes.

Backplane Bus Communication Velocity & I/O Density Scaling
The IC200MDL742H transfers 32 output states over the VersaMax high-speed backplane bus without inducing transmission delays or impacting total program scan velocity. Designers scale field I/O density within minimal cabinet footprints by taking advantage of the module's 32-point sourcing architecture. The electronics draw a maximum of 150 mA at 5 VDC from the backplane rail, maintaining stable backplane bus communication velocity and total firmware flash compatibility across both legacy GE Fanuc racks and modern Emerson automation hosts.
Frequently Asked Questions
Q: How does the IC200MDL742H protect individual output channels during external short circuits?
A: The module incorporates built-in electronic short-circuit and overcurrent protection that limits fault current, alongside internal free-wheeling diodes that suppress inductive voltage spikes generated by field coils.
Q: Can the IC200MDL742H drive negative logic or sinking field loads?
A: No, the IC200MDL742H features a positive logic (sourcing) circuit design, which supplies positive voltage directly to external load devices connected to the common return path.
Q: What power parameters must be provided to keep the output channels operating?
A: The module requires an external secondary field power supply operating within 18 to 30 VDC, while drawing up to 150 mA from the internal 5 VDC backplane supply for logic execution.
Field Installation Guidelines
Mount the VersaMax carrier base securely onto a standard 35 mm DIN rail or directly to a metallic enclosure backplate. Align the IC200MDL742H module with the carrier guide rails and press firmly down until the mechanical retention clips snap into position. Wire field loads to the removable terminal block using 18-22 AWG copper conductors, ensuring field power leads maintain correct 24 VDC polarity. Route output signal cables away from high-voltage AC lines by maintaining a minimum separation distance of 300 mm. Connect the system earth terminal directly to a single-point copper grounding bar to minimize electromagnetic interference.
