GE IC200UEX009-A Expansion Modules

Configured for expansion of I/O processing capabilities in GE VersaMax PLC platforms, the GE IC200UEX009-A (IC200UEX009 Micro Expansion Unit) provides direct physical/electrical execution. The module processes 8 discrete input channels rated at 120 VAC and drives 6 relay output channels (2 rated at 10 A and 4 rated at 2 A) via an integrated 120/240 VAC power supply.

Hardware Specifications

Backplane Bus Communication Velocity & I/O Density Scaling

The IC200UEX009-A scales system I/O density by interfacing directly with the primary VersaMax CPU across the expansion bus. Onboard power conversion optics and isolation barriers decouple high-voltage 120 VAC input circuits and 10 A relay contact switching from the backplane logic bus. This internal architecture preserves high backplane bus communication velocity and logic scan execution during high-current relay switching operations.

Frequently Asked Questions

Q: Can the IC200UEX009-A expansion unit be mated to the main controller while powered?

A: No. Primary AC line power to both the CPU controller and the expansion unit must be de-energized prior to attaching or disconnecting expansion bus cables to protect logic circuitry from transient voltage damage.

Q: What are the distinct load current limits for the integrated relay outputs?

A: The module provides two high-current relay output channels rated up to 10 A and four standard relay output channels rated up to 2 A.

Q: What input power voltage range is required to operate this expansion unit?

A: The unit features an integrated AC power supply capable of operating from a 120/240 VAC supply line.

Field Installation Guidelines

Verify that all AC line power sources are completely de-energized prior to installation. Mount the IC200UEX009-A module on a standard 35 mm DIN rail or secure it to the sub-panel using mounting hardware. Connect the expansion bus cable firmly between the expansion interface ports of the CPU and expansion module. Connect 120/240 VAC power to the main supply terminals and route 120 VAC input field cables separately from output load wiring. Ensure the protective earth terminal is grounded to a low-impedance cabinet chassis ground.
