The GE IC200UEI008, also cataloged as the IC200UEI008 Discrete Expansion Module, operates as a dedicated hardware component for discrete input channel expansion and field sensor power distribution within VersaMax Micro PLC networks. Operating from an external 24 VDC power connection with a nominal 4 W power rating, the unit processes 8 discrete input channels at 24 VDC while supplying an integrated 24 VDC user output rated at 200 mA to power auxiliary field sensors. Up to 4 expansion modules can be attached to a single VersaMax Micro PLC base, extending discrete signal density across localized equipment racks.

High-Density Backplane Bus Processing & I/O Density Scaling
The IC200UEI008 expands local channel capacity without reducing backplane bus communication velocity across attached VersaMax processing nodes. Through deterministic I/O density scaling, discrete field states from all 8 input channels are digitized and passed directly over the local expansion ribbon interface to the primary CPU. Firmware flash compatibility within the main processing unit maintains synchronized image table updating across all attached expansion stages, ensuring state retention during transient DC power sags.
Frequently Asked Questions
Q: How many IC200UEI008 expansion units can be connected to a single VersaMax Micro controller base?
A: A maximum of four expansion units can be daisy-chained to a single VersaMax Micro PLC base via the dedicated expansion bus interface.
Q: What is the maximum current capacity provided by the onboard 24 VDC auxiliary user power output?
A: The auxiliary user output provides up to 200 mA at 24 VDC to directly power connected field devices and input sensors.
Q: What operating ambient temperature range is supported by the IC200UEI008?
A: The unit is rated for continuous operation across an ambient thermal envelope of -20 to 60 deg C.
Field Installation Guidelines
-
Power Isolation: Disconnect main 24 VDC primary power from the controller base and auxiliary field loops before attaching or removing expansion hardware.
-
Expansion Interconnect: Connect the expansion ribbon cable firmly between the expansion bus connector of the main Micro PLC base and the input bus port of the IC200UEI008 module.
-
DIN Rail Mounting: Align the module housing with a standard 35 mm DIN rail and press until the locking tabs snap cleanly into place. Ensure the rail is bonded to protective earth (PE).
-
Sensor Power Wiring: Route 24 VDC field sensor power from the designated 200 mA user power terminals, ensuring total sensor load current does not exceed the 200 mA threshold.
- Signal Wiring & Separation: Route discrete 24 VDC signal cables in separate wiring ducts away from high-voltage AC lines or motor leads to minimize capacitive coupling and EMI noise.
