GE Fanuc 2180/28-001 Power Supply Module

The GE Fanuc 2180/28-001, also cataloged as the 2180/28-001 Power Supply Module, operates as a dedicated hardware component for AC-to-DC power conversion and regulated voltage bus delivery within Series One and Series Three PLC platforms. It converts 115 VAC or 230 VAC line inputs into regulated 5 VDC logic and 24 VDC field auxiliary power outputs across the rack backplane.

Hardware Specifications

Backplane Bus Communication and Deterministic Logic Execution

The power supply maintains continuous backplane bus communication velocity by supplying stable DC power rails to CPU processors and I/O cards, preventing voltage-dip scan halts. Onboard bulk electrolytic capacitors deliver 35 ms of hold-up time to ride through line power transients without triggering system resets. High density component scaling integrates overvoltage and short-circuit protection circuits directly into the single internal PCB assembly, verifying firmware flash compatibility and logic bus integrity across all installed modules.

Frequently Asked Questions

Q: What are the output current ratings for the 5 VDC and 24 VDC rails on the 2180/28-001?

A: The module supplies up to 8 A on the 5 VDC rail for backplane CPU/logic operations and up to 2 A on the 24 VDC rail for field I/O devices.

Q: Can the 2180/28-001 power supply module be hot-swapped while AC mains power is active?

A: No. AC mains line power must be completely disconnected before inserting or removing the power supply from the leftmost rack slot to prevent electrical shock and backplane connector damage.

Field Installation Guidelines

1. De-energize and lock out all AC mains power feeds connected to the power supply input terminal block.
2. Slide the 2180/28-001 module into the dedicated leftmost slot of the Series One or Series Three PLC rack until the 8-pin backplane connector seats fully.
3. Secure top and bottom retaining mechanical fasteners to ensure mechanical stability and panel ground bonding.
4. Wire the 4-pin screw terminal block using 1.5 mm2 stranded conductor wire for the AC input power lines.
5. Ensure a minimum of 50 mm clearance above and below the module for natural convection cooling before applying line power.
