Allen-Bradley 1771-P7 Power Supply Module

Description

The Allen-Bradley 1771-P7 Power Supply Module is a PLC power unit designed for industrial automation control systems, dedicated to delivering direct current (DC) power to PLC I/O modules and associated system components. As part of the Allen-Bradley 1771 Series of PLC modules, it integrates seamlessly with compatible series components, adhering to standard industrial automation control system dimensions and connector types for easy rack integration.

Key technical specifications include dual AC input voltage support of 120V or 220V, a maximum actual input power of 108 watts, and a configurable backplane output current (varies by model and setup) tailored to power connected I/O modules. A core feature is its direct connection capability to the rack backplane, ensuring stable, targeted DC power delivery to support consistent operation of PLC system components. It is optimized for use with PLC-5 systems, providing reliable power distribution for industrial automation environments where consistent, regulated power is critical for uninterrupted control system performance.
