The Allen Bradley 1771-CAP, part of the PLC 5 series, serves as a critical I/O-feedback and emergency stop cable. Spanning 10 ft (3.05 m), it is constructed with a gray jacket and designed for reliable feedback between the controller and emergency stop mechanisms. The cable assembly comes pre-wired for convenience during setup. It features stranded copper conductors, approximately 22 AWG in size, supporting operational voltages near 300 V.

This cable's insulation, rated for PVC and heat-resistant up to 80 °C, ensures durability. The outer diameter measures around 9 mm. The connector system comprises a mating plug that attaches to a terminator, creating a secure connection. Additionally, the keying feature is polarized, preventing accidental misalignment during installation. The device is suitable for temperature conditions ranging from -20 to +80 °C, maintaining functionality in relative humidity levels of 5% to 95% (non-condensing). Typically, this assembly is unshielded, indicating its design caters primarily to environments without excessive electromagnetic interference.
