Allen-Bradley 1756-PA75 ControlLogix AC Power Supply

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.

Technical Specifications

Installation Guidelines

• Mounting Position: Install directly on the far-left slot position of the 1756 ControlLogix chassis.
• Wiring Requirements: Use 2.5 mm2 (14 AWG) solid or stranded copper wire rated at 90 degC or higher, with maximum insulation thickness of 1.2 mm.
• Torque Specifications: Tighten field-wiring conductor screws to 0.565 N-m (5 lb-in).
• Thermal Considerations: Ensure adequate cabinet ventilation so surrounding air temperature does not exceed 60 degC.
