PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-CP3 is a PLC-5 power supply cable assembly. It links the 1771-P7 power supply module to 1771-A1B, 1771-A2B, 1771-A3B, or 1771-A4B I/O chassis. This cable connects a panel-mounted chassis to a chassis-mounted power supply. Dual D-shell connectors secure the link between the power unit and the chassis backplane.
The assembly tolerates bending stress across standard control panel routings. Integrated tightening screws lock each D-shell connector to prevent accidental detachment. It operates in temperatures from 0 to 60 degrees Celsius. Storage temperatures range from -40 to 85 degrees Celsius. The unit supports relative humidity levels from 5 to 95 percent without condensation.
