Excellent PLC
Product Introduction
The Allen Bradley 1756-PB75 ControlLogix DC Power Supply is a high-capacity DC input module developed for demanding ControlLogix automation systems. It converts 18–32 VDC input power into regulated backplane power required to operate ControlLogix processors, communication modules, and I/O cards installed within the chassis.
Designed for industrial panels where 24 VDC nominal distribution is standard, the 1756-PB75 provides increased internal power availability compared to lower-capacity DC models. With a 95-watt output rating, it supports larger rack configurations and systems with higher module density.
Installed on the left side of the ControlLogix chassis, the module operates automatically once powered, delivering consistent internal energy without programming or configuration.
