Configured for high-power field load switching in VersaMax control networks, the GE IC200MDL940A (IC200MDL940A Relay Output Module) provides direct physical/electrical execution. The module facilitates 16 isolated Form A electromechanical relay channels, enabling the interface of diverse field voltage domains including 125 VDC and 240 VAC. It executes command signals from the PLC backplane to actuate field-level output devices, ensuring precise control of resistive and inductive loads within industrial architectures.

Suffix Breakdown & Model Matrix

The IC200MDL940A is a singular hardware configuration within the VersaMax I/O platform. The "A" suffix designates the initial hardware release version. There are no configurable sub-matrix variants for this specific catalog number; the module is designed as a standard 16-point relay output interface.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The IC200MDL940A integrates into deterministic networks to ensure consistent execution timing for output states. The backplane bus communication velocity is managed by the CPU, allowing for sub-cycle response times in coordinated control operations. Firmware flash compatibility within the VersaMax rack enables the system to maintain synchronized I/O scanning, ensuring that the 10 ms relay transition time is accounted for in loop logic. Galvanic isolation between channels and the logic backplane prevents propagation of electrical faults from field power sources to the processor.

Frequently Asked Questions

Q: Can this module be used for high-frequency pulse-width modulation (PWM)?

A: No, the electromechanical nature of the relay contacts restricts switching to a maximum of 20 cycles per minute for inductive loads. High-speed signal switching requires solid-state output modules.

Q: Is hot-swapping supported while the field load is powered?

A: While the module is designed for replacement on a powered rack, it is required to isolate field power from the output terminals before removal to prevent potential damage to the backplane or short-circuiting during extraction.

Field Installation Guidelines

• Mount the module to the designated VersaMax rack slot, ensuring the backplane connector is fully seated to support the 490 mA current draw.
• Terminate field wiring to the removable terminal blocks, ensuring that voltage potentials do not exceed 265 VAC or 125 VDC.
• Implement external suppression circuitry (snubbers or flyback diodes) when switching highly inductive field loads to prevent contact pitting and premature relay failure.
• Verify that all shared commons or individual channel isolation requirements are satisfied according to the system wiring diagram.
• Ensure adequate spacing around the module to facilitate convection cooling, maintaining the operational temperature within the 0 deg C to 60 deg C range.
