Allen Bradley 1756-PB50 ControlLogix DC Standard Power Supply

Product Introduction

The Allen Bradley 1756-PB50 ControlLogix DC Standard Power Supply is a compact and reliable DC input power module designed for the ControlLogix automation platform. It converts external DC power into regulated backplane power required for stable operation of processors, communication modules, and I/O modules installed in the chassis.

This model is typically selected for applications where a DC power infrastructure is already available within the control cabinet. With a 60-watt output capacity and 2.5 amp rating, the 1756-PB50 is well suited for small to medium ControlLogix configurations that require dependable internal power without excessive capacity.

Engineered for industrial environments, the module integrates directly into the left side of the ControlLogix chassis and operates without programming or configuration, providing consistent internal energy distribution across the backplane.
