Allen‑Bradley 1756‑PA72C ControlLogix AC Power Supply Module

Allen‑Bradley 1756‑PA72C is an AC input power supply module for Rockwell ControlLogix PLC chassis. It converts AC mains input into stable DC backplane power for ControlLogix CPU, I/O modules and communication adapter boards within the rack.

This module provides sufficient backplane current capacity for standard ControlLogix chassis, equipped with status LED indicators for operation and fault diagnosis. It is widely supplied as replacement spare parts for factory automation, water treatment and petrochemical control cabinet maintenance projects.
