GE IC200UAR028 Micro Controller

The GE IC200UAR028, also cataloged as the VersaMax IC200UAR028 Micro Controller, operates as a dedicated hardware component for discrete AC input sensing and relay output switching within VersaMax Micro automation platforms.

Hardware Specifications

Backplane Bus Communication Velocity & Firmware Flash Compatibility

• Backplane Bus Communication Velocity: Internal logic processing executes discrete scan cycles with high-speed memory mapping across input and output image tables, maintaining deterministic signal update times for field devices.
• I/O Density Scaling: Integrates 16 high-voltage AC inputs and 12 electromechanical relay outputs into a single compact housing, providing direct high-current load handling without requiring external interposing relays.
• Firmware Flash Compatibility: Onboard flash memory stores user PLC logic and system runtime parameters, permitting firmware updating and program retention during system power-down states.

Frequently Asked Questions

Q: What are the current handling specifications for the relay output channels?

A: The 12 relay output channels are divided into two load ratings: 4 channels support up to 10 A continuous current per point, and 8 channels support up to 2 A continuous current per point.

Q: Can the IC200UAR028 micro controller be hot-swapped while energized?

A: No. The unit is a self-contained micro PLC controller with integrated line-voltage power terminals (120/240 VAC). All power feeds must be de-energized before mounting, wiring, or servicing the module.

Q: What is the nominal input signal voltage required for the discrete inputs?

A: The 16 discrete input channels require a nominal voltage feed of 120 VAC for logic ON threshold detection.

Field Installation Guidelines

1. Disconnect all 120/240 VAC main utility power and field load circuit supplies before installing the unit.
2. Mount the controller onto a standard 35 mm DIN rail or secure it to a grounded metal panel using M4 mounting screws.
3. Establish a low-impedance ground path by connecting a dedicated protective earth (PE) conductor to the ground terminal on the main power terminal strip.
4. Wire the 120/240 VAC input power supply lines to the designated L1, N, and GND power terminals.
5. Terminate 120 VAC field input lines and relay load conductors to the screw terminal blocks, ensuring signal wiring is routed separately from high-voltage AC motor or drive leads.
6. Verify output fuse sizing matches the 10 A and 2 A channel load ratings to protect relay contacts against short-circuit currents.
7. Apply AC power to the unit and verify that the PWR and status LED indicators show normal operational conditions.
