GE Fanuc IC200UEI008 VersaMax Micro Expansion Unit | 8-Point 24VDC Input

Product Overview

The IC200UEI008 is a high-density discrete input expansion module designed specifically for the Emerson (formerly GE Fanuc) VersaMax Micro controller series. This module allows engineers to scale their control systems by adding eight independent 24VDC digital inputs without upgrading the base CPU. It is an essential component for applications requiring additional sensor feedback, offering a dedicated 200mA power output to simplify field device wiring and reduce the need for external power distribution blocks.

Functional Comparison: IC200UEI008 vs. IC200UEX011

• I/O Type: The IC200UEI008 provides 8 dedicated inputs, whereas the IC200UEX011 is a mixed module providing both 8 inputs and 6 relay outputs.

• Power Efficiency: The IC200UEI008 has a lower thermal footprint compared to mixed relay modules, making it ideal for enclosures with limited ventilation.

• Wiring Complexity: The IC200UEI008 includes a dedicated 200mA sensor power supply, which is often omitted in larger mixed-signal expansion units.

Frequently Asked Questions

How is the IC200UEI008 addressed in the PLC configuration?The module is automatically recognized by the VersaMax Micro CPU. Addressing is determined by the module's physical position in the expansion chain (Slot 1 through Slot 4), typically starting at the next available %I address in the PAC Machine Edition software.

Does this module require a separate 24VDC power feed?Yes, the module requires a 24VDC input to power the field-side circuitry and to provide the 200mA sensor excitation voltage.
