Allen Bradley 1784-PCMC Data Highway Plus Assembly

Product Introduction

The Allen-Bradley 1784-PCMC Data Highway Plus Assembly Cable is a bundled industrial communication kit designed to enable notebook computers to interface with Allen-Bradley industrial networks. It supports communication across DH+, DH-485, and Remote I/O systems, making it a practical solution for programming, configuration, and diagnostics of legacy PLC systems.

This package includes the 1784-PCMK PCMCIA communication card and the 1784-PCM5 cable, which together form a complete interface solution for connecting portable engineering devices to PLC networks. The system is widely used in industrial environments where field commissioning and maintenance of control systems are required.

The 1784-PCMK/B card allows a laptop to communicate directly with industrial controllers, while the cable selection ensures compatibility with different PLC families. This modular approach provides flexibility across multiple Allen-Bradley platforms.
