PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-CP1 is a PLC-5 power cable assembly designed for industrial control systems. It links a 1771-P7 power supply module directly to an Allen-Bradley 1771 I/O chassis. Supported chassis models include the 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B series. The assembly features two D-shell connectors equipped with securing screws for stable retention. Its flexible construction allows bending during enclosure routing without placing mechanical stress on wiring conductors.
This cable measures 1.04 feet (0.32 meters) in total length. It provides panel-mounted or chassis-mounted power interconnectivity within standard control cabinets. The cable assembly withstands operating temperatures from 32 to 140 degrees Fahrenheit. It also operates across a relative humidity range of 5 to 95 percent non-condensing. It maintains a storage temperature range between -40 and 185 degrees Fahrenheit.
