Allen Bradley 1769-PB4 Power Supply

The AB 1769-PB4 is a DC power supply module designed for use with CompactLogix and MicroLogix 1500 systems. Delivering up to 2A at 5V DC and 0.8A at 24V DC, this expansion power supply supports a combined power output of 100W and provides reliable operation for a wide range of Compact I/O modules.

With a 24V DC input and compact form factor, the 1769-PB4 mounts directly onto a DIN rail or panel alongside other 1769 modules, supplying power for controller systems and field I/O. It is ideal for distributed and machine-level control installations where efficient, modular expansion is required.
