The AB 1771-P5E is a power supply module designed for Allen-Bradley’s PLC-5 programmable logic controller systems. Here’s a breakdown of its key aspects:

Function

Provides regulated DC power to a PLC-5 chassis and its I/O modules.

Features

• High output current: Delivers up to 8 amps of current at 5 volts DC, ensuring sufficient power for various I/O modules.
• Parallel operation: Can be paralleled with another 1771-P5E for increased current capacity (up to 16 amps total).
• Input power flexibility: Accepts a wide range of DC input voltage (20.5 to 30 volts).
• Built-in protection: Includes a 5 amp fuse for overload protection and supports user-supplied branch circuit protection for added safety.
