Overview
The Allen-Bradley 1784-PCM5 is a Data Highway Plus (DH+) communication cable assembly that connects a notebook or desktop computer equipped with a 1784-PCMK PCMCIA card to legacy PLC controllers. This cable is designed for connecting a computer to a PCMCIA card, facilitating communication with various PLC processors. The cable is 10 feet (3.16 meters) long and has an 8-pin connector, compatible with PCMCIA cards and used to connect them to computers using DH+ protocol.
Key Features
- Supports data transfer rates up to 230 kbps
- RJ45 connector for easy connectivity
- Includes wedges for strain relief, preventing accidental disconnections
- Remote I/O Scanner Capabilities enable integration with remote I/O systems
- Comes with the 1784-CP7 adapter and two wedges that must be attached with the cable to the computer
