The Allen-Bradley 1775-P3 is a multi-output power supply module designed specifically for use within the PLC-3/10 programmable controller system. As a critical component of the PLC-3 architecture, this module provides the necessary regulated DC power rails required for processor operation and I/O chassis backplane communication.

Features

• Designed for integration with Allen-Bradley PLC-3/10 control systems.
• Multi-output configuration to support diverse internal system voltage requirements.
• Robust industrial construction suitable for standard control cabinet environments.
• Direct replacement or spare for legacy 1775-P3 installations.

Applications

This power supply is intended for use in legacy industrial automation environments where PLC-3/10 processors are currently deployed. It is typically installed in the primary or expansion chassis to ensure stable power delivery to the CPU, communication modules, and digital/analog I/O cards.

Technical Specifications

Installation Guidelines

• Ensure the main power source is disconnected before attempting to install or remove the module from the chassis.
• Verify that the module is fully seated in the designated power supply slot to ensure proper backplane connection.
• Maintain adequate clearance around the module to allow for proper airflow and heat dissipation.
• Handle the module using ESD-safe procedures to prevent damage to internal circuitry.
• Check that the input voltage matches the module specifications before energizing the system.
