Allen Bradley 1756-PBXT ControlLogix XT DC Power Supply

Product Introduction

The Allen-Bradley 1756-PBXT is a ControlLogix XT DC power supply engineered for use in extreme industrial environments. Designed as part of the ControlLogix XT (Extended Temperature) series, this power supply delivers stable backplane power to ControlLogix chassis systems operating in harsh conditions where standard temperature-rated modules may not be suitable.

The 1756-PBXT converts a DC input voltage into regulated backplane power required by ControlLogix controllers, communication modules, and I/O modules. With a 52-watt output capacity, it supports a wide range of system configurations while maintaining consistent voltage regulation and thermal stability.

Built for demanding industries such as oil & gas, mining, power generation, and heavy manufacturing, the XT series ensures reliable performance across expanded temperature ranges. The 1756-PBXT integrates directly into the left side of a ControlLogix chassis and supplies power through the backplane without requiring additional wiring to individual modules.
