【英文介绍】

Allen-Bradley's 1771-P4R PLC 5 Redundant power supply module is an electrical device located in the 1771 chassis that improves system availability and reduces machine downtime due to system power failures. In the event of a power failure, it prevents system interruption or a complete stop of system operation. The 1771-P4R has an input voltage range of 97-132V AC (50-60Hz) and provides 5V DC (8A) output current. The module has an N+1 design feature and provides a maximum output current of 8A(2-unit system), 14A(3-unit system) and 20A(4-unit system) at 60 degrees Celsius using the N+1 module. The maximum power consumption is 16W, the adjacent slot is 10W, and the maximum heat dissipation is 47.8 BTU/hr. The 1771-P4R module delivers 300mA backplane current at 5V DC and has been tested to withstand 1000V voltage isolation for 1 second. The 1771-P4R circuit comes in a 2.5mm2 copper wire size with 3/64 inch insulation, a temperature rating of 60 degrees Celsius, and comes with redundant cables. It provides a 15A branch circuit protection, and it also provides circuit protection through a 1.5A 250V AC slow fuse and a Bussman MDL 1.5 fuse. The module has alarm circuits rated AC 24-250V, 1/6HP, 1A and 30V DC. The 1771-P4R is tested for operating temperatures ranging from 0 to 60 degrees Celsius, non-condensing relative humidity of 5-95%, no degradation, and is CSA, NEMA, and ul certified.

The Allen-Bradley 1771-P4R is a power module used with the 1771 Programmable Logic Controller (PLC) product family. This module is specifically designed to increase the uptime and availability of the system, as it allows pairing to another 1771-P4R, providing an additional layer of protection along the power supply line. With a redundant power supply configuration, the power supply units operate simultaneously, with the output of one unit acting as a backup power supply. When the active power supply unit fails or shuts down, the secondary active power supply takes over to prevent unnecessary shutdown or shutdown of the system.

The 1771-P4R operates at an input voltage range of 97-132 VAC and a frequency of 47-73 Hz. It provides 5 volts DC output voltage and 8 amps output current to the backplane. It comes with a 1.5 amp, 250 volt AC rated integral fuse. The module occupies only one slot in the 1771 chassis. In addition, it is equipped with an output alarm rated at 250 volts AC.

The 1771-P4R is designed for 2-unit systems with a maximum system output current of 8 amps; 3 units is 14 amperes, 4 units is 20 amperes. These ratings use N+1 redundancy at 60 ° C operating environments.

The line connected to the module is terminated to the block of the module. The Allen-Bradley block for this module has Allen-Bradley part number 941274-05 and equivalent Wago part number 231-205/000-008. In addition, the relay wiring block for this power supply is 941274-03 and the equivalent Wago part number is 231-203/000-008.
