Allen-Bradley 1771-P4SGE | Power Supply Module

Overview

The 1771-P4SGE from Allen-Bradley is a reliable single-slot power supply module. It delivers 5VDC at a maximum current of 8 Amperes, powering the backplane of any compatible 1771 series module. This unit ensures stable operation for PLC-5 automation systems.

Compatibility

The 1771-P4SGE works seamlessly with 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B Universal I/O Chassis. Additionally, it supports parallel operation using a 1771-CT cable, enabling higher power delivery without expanding to a second chassis.

Electrical Specifications

The 1771-P4SGE operates with an input voltage range of 97–132VAC and frequency range of 47–63 Hz, with a nominal voltage of 120VAC. It consumes a maximum real power of 59 Watts and an apparent power of 89 VA. A 1.5A, 250V slow-blow fuse protects the module.

Physical Specifications

This single-slot module fits standard 1771 chassis and accommodates wire sizes up to 14 AWG for single wires. It includes a 5-position terminal block (A/B P/N 941274-05; Wago 1 P/N 231-205/000-008) for reliable connections. The compact design minimizes rack space while maintaining optimal airflow.

Functionality

The 1771-P4SGE delivers consistent 5VDC to all connected modules. Its backplane output current reaches 8 Amperes, supporting multiple I/O and communication modules efficiently. The module ensures stable system performance, allowing uninterrupted automation operations.
