Product Description

Allen-Bradley 1771-P2 PLC-5 Backplane Power for 1771 I/O Chassis

The Allen-Bradley 1771-P2 is an auxiliary power supply module designed to deliver regulated 5V DC power directly to the backplane of 1771 Universal I/O chassis used in PLC-5 automation systems. It installs within the chassis and operates from an AC input source.

Integrated Chassis Power Delivery

  • Provides regulated 5V DC power directly to the 1771 chassis backplane
  • Designed specifically for Allen-Bradley 1771 Universal I/O chassis
  • DC ON indicator confirms active backplane power output
  • Occupies two slots within the 1771 I/O chassis

Electrical Design and Protection

The 1771-P2 supports jumper-selectable AC input voltages and includes built-in protection circuitry. Monitoring for overvoltage, undervoltage, and overcurrent conditions helps protect connected I/O modules by shutting down output if abnormal conditions occur.

Industrial Automation Applications

  • PLC-5 systems using 1771 Universal I/O chassis
  • Industrial control panels requiring internal chassis power
  • Legacy Allen-Bradley automation platforms
