Allen-Bradley 1756-PB75 ControlLogix Power Supply
Description
The Allen-Bradley 1756-PB75 is a 24V DC power supply module belonging to the ControlLogix series, designed for industrial control systems. It features a wide input voltage range of 85-264VAC, which supports major global industrial power grid standards for universal deployment. The module delivers a main output of 24VDC, with dual auxiliary outputs of 5VDC/5A and 24VDC/3A, providing a total power of 75W at 60 degrees Celsius and a backplane current output of 13A, with support for parallel operation of multiple modules for expanded power capacity. Key functional features include compatibility with the 1756-PB75R redundant module to achieve uninterrupted power switching, and hot-swappable capability that allows module replacement during system operation without power shutdown. It integrates a built-in status monitoring chip to real-time feed back parameters such as input voltage, output current, and temperature, and communicates with the control system via the backplane bus, supporting monitoring through RSLogix5000 software. Operating within a temperature range of 0 to 60 degrees Celsius, it meets international certification standards including CE, UL, CCC, and complies with SIL2/SIL3 safety requirements, making it suitable for most harsh industrial environments.
