Allen-Bradley 1756-PA75R Power Supply Module

The Allen-Bradley 1756-PA75R Power Supply Module is a backplane power supply designed for 1756 ControlLogix I/O chassis. In a ControlLogix installation, this module sits in the dedicated power supply slot and provides the backplane with the power needed to drive the chassis and its I/O modules, enabling consistent operation of the system. As part of the 1756 Power Supply family, the 1756-PA75R interfaces with the 1756 backplane to support the voltage rails that feed I/O modules and processors within compatible ControlLogix configurations. It is designed for use alongside other Allen-Bradley 1756-series components, including controllers, I/O modules, and communication modules, in industrial automation environments. When selecting this part, verify that your chassis is 1756-compatible and that the power supply slot and configuration meet your system requirements.
