SKU CH-1M7B-2RFA5

A USB-to-Data-Highway-Plus cable connects a PC or laptop to PLC-5 or SLC 5/04 processors on DH+ networks, replacing legacy adapter cards and cables

  • Connect PC or laptop directly to DH+ networks via USB
  • Replaces 1784-PCMK adapter card and 1784-PCM6 cable
  • Supports PLC-5 and SLC 5/04 processors
  • Factory sealed 2022 stock from Allen Bradley
  • Simple USB interface for legacy industrial networks

Allen-Bradley 1784-U2DHP USB-to-DH+ Cable

The 1784-U2DHP cable connects a PC or laptop USB port directly to Data Highway Plus networks for PLC-5 and SLC 5/04 processors. It removes the need for an internal adapter card or separate communication cable. Factory-sealed 2022 stock ensures reliable links for legacy automation tasks.

Industrial-Grade Connector and Shielded Cable

A rugged DB-9 style DH+ connector locks into the network trunk while the USB-A plug fits standard ports without extra drivers. Shielded conductors resist electrical noise common in control cabinets. The single-cable design reduces clutter and eliminates the separate 1784-PCMK card and 1784-PCM6 cable combination.

Replaces Legacy PCMK Adapter and PCM6 Cable

This unit supersedes the two-piece 1784-PCMK/PCM6 setup, cutting hardware count and potential failure points. The jump is worth it when maintaining older PLC-5 or SLC 5/04 systems that still run on DH+ and a modern laptop lacks a card slot. Not suited for ControlNet, EtherNet/IP or DeviceNet networks.

Highlights

  • Connect PC or laptop directly to DH+ networks via USB
  • Replaces 1784-PCMK adapter card and 1784-PCM6 cable
  • Supports PLC-5 and SLC 5/04 processors
  • Factory sealed 2022 stock from Allen Bradley
  • Simple USB interface for legacy industrial networks
