Allen-Bradley 1771-CP2 PLC-5 Power Supply Cable Assembly
The Allen-Bradley 1771-CP2 is a 5-foot (1.52-meter) power supply interconnect cable assembly designed for the PLC-5 architecture. It bridges power from a standalone or remotely mounted 1771-P7 power supply module to 1771 Universal I/O rack chassis models, including the 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B series. Equipped with dual D-shell connector terminations and integral thumbscrews, it ensures stable low-voltage power distribution to the backplane across industrial environments.
Mechanical Interconnect and Construction
The 1771-CP2 assembly utilizes flexible industrial routing wire engineered to accommodate panel bends without inducing fatigue stress on internal conductors. Dual D-sub connectors located at both ends plug into matching receptacles on the remote power supply and target chassis. Integral captive thumbscrews provide mechanical strain relief and lock the assembly against cabinet vibration. A conformal coating over sensitive connection points enhances resilience against atmospheric contaminants, humidity, and wear in harsh industrial installations.

System Integration and Installation Practice
When installing the 1771-CP2 between a remote 1771-P7 power supply and a target 1771 I/O chassis, ensure control power is completely de-energized before making physical connections. Route the cable through dedicated low-voltage wire runs, maintaining physical separation from high-voltage AC lines to minimize electromagnetic noise pickup. Hand-tighten both connector D-shell screws securely to ensure continuous grounding and uninterrupted backplane power delivery.
