Allen Bradley 1784-CP10 Cable Assembly

Product Introduction

The Allen-Bradley 1784-CP10 Cable Assembly is a serial communication cable designed for connecting IBM-compatible computers to PLC-5 controllers. It provides a reliable interface between a standard 9-pin serial port (DB9) on a PC and a 25-pin serial port (DB25) on the PLC system, enabling configuration, programming, and diagnostics.

This cable is commonly used in industrial automation environments where direct serial communication is required for controller setup or maintenance. It ensures stable data transmission between engineering workstations and PLC hardware, supporting efficient commissioning and troubleshooting processes.

Built with industrial-grade shielding and durable connectors, the 1784-CP10 is designed to minimize signal interference and maintain reliable communication in electrically noisy environments typical of industrial plants.
