The Allen-Bradley 1756-CPR2U is a 1756 Right Angle Redundant Power Supply Cable UP to transfer power in a ControlLogix System.
The redundant power supply has various additional features over the standard power supply. Some of these are automatic chassis load sharing, operating status indicator, solid state relay, and operation anomaly restricted to only the power supply, excluding cables and adapters.
The 1756-CPR2U Redundant Power Supply Cable has a cable length of 0.91 meters (3 feet) and it weighs 0.3 pounds. It has an input current of 970 mA at 5.1V DC and 1.7 mA at 24V DC. It supports ControlNet communication at a speed of 5 megabits per second. The 1756-CPR2U has a maximum power dissipation of 5.1 W and thermal dissipation of 17.4 BTU per hour. It is mounted in a chassis with open enclosure and with 4-in. (101.6 mm) clearances at the top and sides.
The 1756-CPR2U Redundant Power Supply Cable has reduced the minimum required installation from more than 5 inches (152.4 mm) to less than 2 inches (50.8 mm) for the redundant power supply. It supports all series of standard redundant power supplies in a ControlLogix System. XT cable adapters and power supplies are compatible with it. The 1756-CPR2U is RoHS (Restriction of Hazardous Substances) compliant and has the same cost as other standard cables.
