PLC-5 Backplane Power Integration
The 1771-P4S provides regulated 5 VDC power to the PLC-5 1771 chassis backplane. The module occupies one chassis slot and supports parallel connection with compatible power supply units including -LSP, -LWP, -XP, -ZP, and additional -P4S units for increased system power capacity.
The power supply architecture is designed for PLC-5 I/O rack configurations, supplying backplane current for installed controller and I/O modules. The module uses the 1771-CT cabling configuration for supported parallel power arrangements.

Field Installation Guidelines
Install the 1771-P4S module in the designated power supply slot of a compatible 1771 chassis. Verify that the chassis configuration supports the module before installation.
Connect AC input wiring according to terminal block requirements and maintain correct conductor sizing. Ensure the protective grounding connection follows the installation site's electrical standards.
When using parallel power supply configurations, install approved cabling and verify compatibility between connected supply modules. Confirm input voltage, fuse condition, and backplane power availability before applying system power.
Keep AC power wiring separated from low-level signal wiring to reduce electrical interference. Perform voltage verification at the chassis backplane before installing or replacing I/O modules.
