The 1771-P4R PLC 5 Redundant Power Supply Module by is an electrical device located in the 1771 Chassis which increases system availability and reduces machine downtime resulting from a failed power supply in the system. It prevents system interruption or complete shutdown of the system’s operations when there is a power failure.

The 1771-P4R has an input voltage range of 97-132V AC at 50-60Hz and provides a 5V DC output current at 8A. The module has a N+1 design feature and the maximum output current provided by the module using N+1 at 60 degrees Celsius is 8A (for a 2-unit system), 14A (for a 3-unit system), and 20A (for a 4-unit system). Its 16W maximum power dissipation with a 10W dissipation on the adjacent slot and with a 47.8 BTU/hr maximum thermal dissipation.

The 1771-P4R module provides a 300mA backplane current at 5V DC and is tested to withstand 1000V voltage isolation for 1 second. The 1771-P4R circuitry uses the 2.5mm2 copper wire size with 3/64-inch insulation thickness rated at 60 degrees Celsius and is shipped with a redundancy cable. It provides a 15A branch circuit protection and it also provides circuit protection through the 1.5A 250V AC Slow Blow fuse and with the Bussman MDL 1.5 fuse. The module has an alarm circuit with a rating of 24-250V AC, 1/6HP, 1A, and 30V DC. The 1771-P4R has a tested working temperature range between 0 and 60 degrees Celsius at 5-95% non-condensing relative humidity, without de-rating, and is CSA, NEMA, and UL-certified.

The 1771-P4R is a Power Supply module that is used with the 1771 Programmable Logic Controller (PLC) product family. This module is specifically used to increase the system uptime and availability 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 one unit’s output relegated as standby source. When the active power supply unit fails or shuts down, the secondary active supply takeover, preventing unwanted stoppage or shutdown to the system.
