Product Description
The Allen-Bradley 1772-P1 is an auxiliary power supply PCB designed to power Allen-Bradley Bulletin 1772 PLC-2 processors and their I/O chassis. It converts facility AC power (110V or 220V) to 24V DC for the PLC-2, but does not provide battery backup as the PLC-2 has internal memory retention. This open-style module, weighing approximately 15.5 pounds, mounts on a 1772 PLC-2 chassis and includes a 2A 250V slow-blow fuse for protection. Users must protect it from environmental hazards like liquids, moisture, and debris, ideally with a protective enclosure. Installation, maintenance, and repair should only be performed by trained personnel due to electric shock and ESD risks.
Is Your Device Showing These Signs?
The Allen Bradley 1772-P1 power supply frequently experiences issues such as capacitor degradation leading to voltage instability and system faults. Technicians address failures stemming from excessive heat causing component stress and reduced lifespan. Common repairs include replacing failed electrolytic capacitors, rectifying diode malfunctions, and resolving transformer burnout. Troubleshooting often reveals issues with the power supply's inability to deliver the required current, resulting in PLC operational errors and complete system shutdowns. Addressing these problems restores the 1772-P1 to proper functionality, ensuring stable and reliable power delivery for the PLC system.
