The Allen-Bradley 1771-P2 is an auxiliary power supply module designed for use with the PLC5 system, specifically for one 1771 chassis fitted with a communication adapter, 1771 Mini-PLC2, or 1771-Mini-PLC 2/15. This module supports dual voltage operation, accommodating both 120V AC and 220-240V AC inputs, with factory settings defaulted to 120V AC. Offering both overvoltage and overcurrent protection, the 1771-P2 ensures reliable performance with a maximum output of 6.5 A at 5.1 VDC. With self-monitoring capabilities, this power supply can automatically shut down in the event of an error, providing a quick response solution before power cycling to prevent operational disruptions. This power supply demands specific slow-blow fuses depending on its operational mode, requiring a 1 A slow-blow fuse for 120V AC and a 0.5 A fuse for 220-240V AC. Operating within a frequency range of 50-60 Hz, the module ensures robust and stable power delivery, with isolation voltages maintaining 2500V DC and 1800V RMS for enhanced safety.
