The Allen-Bradley 1771-P7 is a robust standalone power supply unit tailored for the 1771 I/O chassis, compatible with the Mini-PLC-2 series and PLC-5 programmable controllers. Designed for specific chassis models, namely 1771-A1B, -A2B, -A3B, -A3B1, and -A4B, it delivers a maximum output of 16A at 5.06V DC with input current options of 120V AC at 2.0A or 220V AC at 1.0A, and operates within a frequency range of 47-63Hz. Equipped with a D-Shell power connector, it supports connection to the PLC5 backplane using designated cables and requires careful installation to avoid electrostatic discharge and ensure operational safety, never being used in parallel configurations to prevent risks such as data loss or system malfunctions.
