Product Overview
When your control system requires reliable switching of DC loads, the GE Fanuc IC200MDL741 Discrete Output Module delivers consistent performance. This Versamax series module provides 16 discrete outputs in a single group, each rated for 24 Volts DC nominal and 0.5 Amps. Designed for positive logic operation, the IC200MDL741 switches the load to the positive side of the external DC supply by sourcing current to the load. Its compact, modular architecture makes it an affordable and scalable solution for expanding PLC applications.
Technical Specifications Breakdown
The IC200MDL741 offers several key specifications that define its capabilities:
- Output Voltage: 18 to 30 VDC, with a nominal rating of 24 VDC. This wide range accommodates varying DC power supplies while maintaining consistent switching performance.
- Number of Points: 16 discrete outputs arranged in 1 group. All outputs share a common return, simplifying wiring for grouped field devices.
- Backplane Current Consumption: 5 Volts at 75 milliamps. This low draw minimizes the load on the backplane power supply, leaving capacity for other modules.
- Protection: Short circuit and overcurrent protection, plus free-wheeling diodes. These features safeguard the module and connected loads from electrical faults.
- LED Indicators: One LED per point shows on/off and overload status, while the "OK" and "FLD PWR" LEDs indicate module health and field power presence.

This module is ideal for applications requiring sourcing outputs and robust protection.
Industry Applications
The IC200MDL741 excels in discrete manufacturing and process control environments. Common uses include:
- Conveyor Systems: Control solenoid valves and motor starters in material handling lines. The 0.5 A per point handles small DC loads directly.
- Packaging Machinery: Activate indicators, alarms, and small actuators. The LED per point simplifies troubleshooting on fast-paced lines.
- Assembly Stations: Switch DC-powered sensors and pilot lights. The 18-30 VDC range matches typical industrial DC supplies.
Installation & Setup Guidance
Mount the IC200MDL741 on a DIN rail that is electrically grounded for EMC protection. The module supports hot insertion, allowing installation or replacement without powering down the system. Connect the external power supply (18 to 30 VDC) to terminals A17 (DC+) and A18 (DC-) on the I/O carrier. Ensure the field devices served by this module do not exceed 0.5 Amps per output. The module can be oriented in any position on the rail.
Maintenance & Reliability
Regular inspection of the LED indicators helps identify overloaded or faulty outputs quickly. The short circuit and overcurrent protection reduce the risk of damage from wiring errors. Because the module uses electronic protection rather than fuses, there are no consumable parts to replace. Verify that the external power supply remains within the 18-30 VDC range to ensure reliable switching. For long-term reliability, keep the module free of dust and moisture.
Compatibility & Integration
The IC200MDL741 integrates seamlessly with the GE Fanuc Versamax series backplane. It communicates with the CPU via the backplane bus, requiring no additional configuration for basic operation. The module's open architecture supports a wide variety of communication options available in the Versamax system, including Ethernet, Profibus, and DeviceNet, depending on the network interface module used.
Selection Guide & Purchasing Advice
Before purchasing the IC200MDL741, verify that your system requires sourcing (positive logic) outputs and that your external power supply provides 18-30 VDC. Confirm that your I/O carrier supports this module and that the backplane can supply 75 mA at 5 VDC. SpareTechPLC stocks the IC200MDL741 and can advise on compatible carriers and network modules. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
