1756-PB72

Designed by Allen Bradley, the 1756-PB72 is a reliable power supply module intended for use in ControlLogix systems. It operates optimally at a nominal input voltage of 24V DC, with a versatile input voltage range from 18V to 32V DC, accommodating various operational environments. This module has the capability to deliver up to 75 Watts of output power when maintained within a temperature interval of 0 to 60 degrees Celsius.

It also supports a maximum input power of 95 Watts, ensuring that it can sufficiently power connected devices. Inrush current ratings reach up to 30 Amps, providing necessary power surges during startup without compromising safety or functionality.

Isolation capabilities are noteworthy, with a continuous isolation voltage rated at 250 Volts. The module features reinforced insulation, significantly enhancing safety and reliability during operation. Isolation is available between power input and backplane, further protecting sensitive components.

Notably, the enclosure type is classified as open-style, meaning it does not have a housing, allowing for direct exposure to the installation environment. For ease of installation, the conductor screw torque specification is set at 0.565 Nm, facilitating secure connections. Overall, the 1756-PB72 power supply module is a key component for efficient operation within automated control systems.
