Description
Allen-Bradley 1771-P2A Power Supply Module
The Allen-Bradley 1771-P2A, also cataloged as the 1771-P2A Power Supply Module, operates as a dedicated hardware component for regulated backplane power delivery within PLC-5 and Bulletin 1771 I/O chassis platforms. The module converts selectable 120/240 VAC input power into a 5.1 VDC output supply for chassis-mounted I/O modules and processor interface hardware.

PLC-5 Backplane Power Architecture
The 1771-P2A provides regulated 5 VDC power for Bulletin 1771 I/O chassis backplane operation. The module uses selectable AC input configuration through jumper settings and supplies DC power directly to connected I/O modules and compatible processor adapter configurations. The power output capacity supports single chassis operation and can be combined with a compatible 1771-P10 power supply through a 1771-CT cable for increased current capacity.
The module interfaces with Allen-Bradley PLC-5 hardware through the 1771 chassis power distribution structure. Its power conversion design includes AC input filtering, regulated DC output control, and chassis backplane current delivery for installed modules.
Frequently Asked Questions
Q: What output voltage and current does the 1771-P2A provide?
A: The module provides a regulated 5.1 VDC output with a maximum backplane current capacity of 6.5 A.
Q: Can the 1771-P2A operate from different AC input voltages?
A: Yes. The input configuration supports selectable 120 VAC or 220/240 VAC operation through jumper selection.
Q: How is the 1771-P2A installed in a PLC-5 system?
A: The module mounts in a Bulletin 1771 I/O chassis and occupies two chassis slots while supplying power to the backplane.
Field Installation Guidelines
Install the 1771-P2A only in compatible Bulletin 1771 chassis configurations. Verify the AC input jumper configuration before applying power to match the available supply voltage.
Maintain adequate airflow around the module to support heat dissipation within the specified operating temperature range. Route AC input wiring separately from low-level signal cables to reduce electrical interference. Connect chassis grounding according to industrial control panel grounding practices and maintain proper shielding termination for adjacent signal wiring.
When paralleling power supplies, confirm compatibility between supply models and use the specified interconnection cable. Inspect backplane loading requirements before installation to ensure the total module current demand remains within the available 5 VDC supply capacity.
