Description

The Allen-Bradley 1756-PB72 is a standard DC power supply module designed for the ControlLogix platform. It provides reliable power distribution to the ControlLogix chassis, ensuring stable operation of the CPU, I/O modules, and communication adapters within the rack. This unit is engineered for industrial environments requiring a 24V DC input source.

Features

• Designed specifically for the Allen-Bradley ControlLogix chassis system.
• Supports an input voltage range of 18-32V DC.
• Delivers a power output of 75W at 60 degC.
• Robust chassis-mount design for secure installation.
• Integrated protection against input voltage fluctuations.

Technical Specifications

Installation Guidelines

• Ensure the ControlLogix chassis is powered down before installing or removing the power supply module.
• Slide the module into the designated power supply slot on the left side of the chassis until it is fully seated.
• Tighten the mounting screws to ensure a secure connection and proper chassis grounding.
• Use appropriate wire gauges for the DC input terminals to prevent voltage drops and overheating.
• Maintain adequate clearance around the module to allow for proper airflow and cooling, as the unit is rated for performance up to 60 degC.
• Avoid routing high-voltage AC cables near the DC input wiring to minimize electromagnetic interference (EMI).

FAQ

Is the 1756-PB72 compatible with all ControlLogix chassis?

Yes, this power supply is designed to be compatible with standard ControlLogix chassis, provided the chassis has the appropriate slot for a power supply module.

What is the primary function of this module?

The 1756-PB72 converts 24V DC input power into the necessary voltages required by the backplane to power the modules installed in the ControlLogix rack.
