Allen-Bradley 1756-PB75 ControlLogix Power Supply

The Allen-Bradley 1756-PB75 ControlLogix Power Supply is a chassis-mounted DC power module that delivers 75 W of backplane power to ControlLogix controllers and I/O within a 1756-series chassis. It runs from 18–32 V DC input (24 V DC nominal) and distributes stable power across the ControlLogix backplane to support controllers, communication modules, and I/O modules. LED indicators provide power and module-status feedback, and the unit operates from 0°C to 60°C. Typical uses include manufacturing lines, packaging machinery, conveyors, and other process automation setups, and it is used by maintenance teams, OEMs, and system integrators for installations, automation upgrades, chassis expansions, and replacement of existing power modules; common replacements include 1756-PB72, 1756-PA75, and 1756-PA72.
