Allen-Bradley 1746-P2 SLC 500 Series PLC Module

The Allen-Bradley 1746-P2 is a SLC 500 power-supply module designed to fit in a 1746 chassis and provide the DC rails that feed the processor, memory, and I/O modules in an SLC 500 system. It accepts 120/220 VAC input (47–63 Hz) and draws about 70 watts of input power, delivering a DC output range of 18–30 VDC to the backplane. The backplane current capability is 5 A on the 5 V rail and 0.96 A on the 24 V rail. Dimensions are approximately 5.5 x 2.9 x 5.7 inches, with an operating temperature range of 0–60 °C (storage to -40 to 85 °C) and humidity up to 95% RH. This module is a foundational power component within the SLC 500 family, enabling reliable operation of the processor, memory, and I/O modules in industrial environments.
