Description

The Allen-Bradley 1756-PA75 is a standard ControlLogix AC power supply designed to mount directly onto the left side of a 1756 ControlLogix chassis. It converts standard alternating current input into regulated DC power to supply the backplane, supporting system controllers, I/O modules, and communication modules. The 1756-PA75 delivers up to 75 W of total output power at surrounding operating temperatures up to 60 degC.

Features

Mounts on the left side of compatible 1756 ControlLogix chassis.
Wide input voltage capability supporting nominal 120V/240V AC ranges.
Multi-voltage DC backplane power distribution providing 1.2V DC, 3.3V DC, 5.1V DC, and 24V DC outputs.
Reinforced insulation isolation between power input and the chassis backplane.

Applications

Industrial Control Systems using ControlLogix PAC platforms.
Factory automation backplane power distribution.
Process control cabinet installations requiring high-reliability AC power inputs.
