Allen-Bradley 1771-P2A PLC5 Auxiliary Power Supply

Product Overview

The Allen-Bradley 1771-P2A is an auxiliary power supply module engineered for PLC5 systems. It provides reliable 5V DC output at 6.5A to power a single 1771 I/O chassis installed with an adapter module.

This module operates at either 120V AC (.75A) or 220–240V AC (.38A), accommodating varied industrial environments. Its maximum real input power reaches 65W at full load, ensuring consistent energy delivery to connected devices.

Equipped with fuse protection, the 1771-P2A uses a 1A slow-blow fuse for 120V AC or a 0.5A fuse for 220–240V AC operation. The unit supports input voltages ranging 98–132V AC and 196–250V AC, with frequency compatibility of 50–60 Hz.

Designed for robust operation, the 1771-P2A maintains logic circuitry and memory at 5.1V DC ±5%, with a 13.5 ms ±2.5 ms power-loss delay to prevent immediate system shutdown. Operating temperatures range from 0°C to 60°C, and storage temperatures extend from -40°C to 85°C.
