Features:

  • 75W Maximum Output Power
  • Chassis-Mount Design
  • Multi-Voltage Backplane Power
  • Robust Isolation Voltage
The 1756-PB75 from Allen Bradley is a power supply module specifically designed for ControlLogix systems. It has a nominal input voltage of 24V DC, functioning within an input voltage range of 18-32V DC, allowing it to accommodate varied conditions.

The Power Supply Module 1756-PB75 by Allen Bradley serves effectively in applications requiring stable power input. Operating primarily at a nominal voltage of 24V DC, it handles a range of 18 to 32 volts DC. The unit is capable of supplying up to 95 watts of power on input, while it maintains a consistent output power of 75 watts within the operating temperature spectrum of 0 to 60 degrees Celsius.

The 1756-PB75 Allen-Bradley Power Supply Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The module is engineered to occupy the dedicated slot on the far-left end of the standard 1756 chassis, leaving all remaining slots free for application-specific modules. It converts the incoming 24V DC input into four distinct voltage outputs required by the complex circuitry of different ControlLogix modules: 1.2V, 3.3V, 5.1V, and 24V DC. With a maximum output power rating of 75W, it provides sufficient current capacity to support demanding, fully populated chassis configurations. To protect the sensitive logic cards on the backplane, the 1756-PB75 features overcurrent and overvoltage safeguards, alongside a robust 250V continuous galvanic isolation barrier between the incoming power source and the backplane logic.
