1756-PAR2  ControlLogix Redundant Power Supply kit

The Allen-Bradley 1756-PAR2 is a bundled system composed of products that belongs to the ControlLogix

product family. The 1756-PAR2 is composed of Two (2) 1756-PA75R power supplies, Two (2) 1756-CPR2 cables and One (1) 1756-PSCA2 Chassis adapter module.

The 1756-PA75R is a redundant power supply use along another power redundant unit. This type

of power supply provides failsafe protection and ideally used in critical application that require minimized

risks of application downtime. The has an input voltage range of 85-264VAC, 47-63 Hz with nominal input

voltage of 120 / 240 VAC along an nominal input frequency of 50/60 Hz. This power supply provides maximum

output power of 75 Watts and current capacities of 1.5 @ 1.2 VDC; 4 A @ 3.3 VDC; 13 A @ 5.1 VDC and 2.8 A @ 24VDC.

The 1756-CPR2 is a redundant power supply cable that is used to connect both the power supplies for

synchronization and perform internal communication. This cable measures 0.91 m or 3 ft with minimum cable bend radius of 12.7 cm or 5 inches.

1756-PAR2 

To set up the 1756-PAR2 power supply, attach a standard power supply to the left end of the framework and

fasten it directly to the backplane. This unit is built with smart and rugged technology, giving the 1756-PAR2

ControlLogix-XT power supply the ability to withstand extreme temperatures and tough environments. A redundant

power supply system provides extra uptime protection for chassis that are used in critical applications; it funnels

power through the chassis adapter to the ControlLogix series B chassis backplane. To build a redundant power

supply system, a redundant power supply system that offers additional protection for the framework being used in

significant applications is required. The power supply directs the power through the framework adaptor to the ControlLogix series B framework backplane.
