1784-PCM5 | Allen-Bradley DH+ Communication Cable for PCMK Cards (230 kbps)

Allen-Bradley · PLCs & Industrial Controllers

Description The Allen-Bradley 1784-PCM5 is a DH+ communication cable designed for interfacing 1784-PCMK communication cards with PLC-2, PLC-3, and PLC-5 controllers. Supporting a 230 kbps Data Highway Plus network, the 1784-PCM5 ensures reliable data exchange between industrial control systems and PC-based programming devices. Its wedge-supported connector design provides secure strain relief and protects both the cable and communication card during field use.     Technical Specifications Condition New/Never Used Surplus Brand Allen-Bradley Category Communication Cable Part Number 1784-PCM5 Subcategory Communication Cable Series PLC 5 Cable Type DH+ communication cable Communication Speed 230 kbps Connector Type RJ45 Compatible Cards 1784-PCMK / PCMK/B PCMCIA cards Supports Remote I/O Yes Diagnostics Loopback test supported (card only) Included Accessories Connection wedges for strain relief Typical Applications PLC-2, PLC-3, PLC-5 communication, PC-based programming Environment Industrial control systems Wedges Requirement Must be installed to protect PCMK card and connector Network Type Data Highway Plus (DH+) Use Case Programming, monitoring, and diagnostics     Information About 1784-PCM5 The 1784-PCM5 belongs to the Allen-Bradley PLC-5 accessory family and enables notebook or PC-based DH+ communication through the 1784-PCMK/B PCMCIA card. It links directly to enhanced and standard PLC processors, allowing configuration, monitoring, and troubleshooting over a DH+ network. The cable includes two mechanical wedges to maintain connector stability and prevent accidental disconnection—an essential feature for industrial environments where vibration or movement is present. Compatible with loopback diagnostics when attached to the PCMK card (not to a live DH+ link), the 1784-PCM5 also supports remote I/O scanner capabilities for expanded communication functionality. Key Features DH+ Communication Cable: Provides connectivity to Data Highway Plus networks at 230 kbps. PCMK Card Compatible: Designed for 1784-PCMK and 1784-PCMK/B PCMCIA communication cards. Secure Connector Wedges: Includes strain-relief wedges to prevent accidental cable disconnection. Supports Legacy PLCs: Interfaces with PLC-2, PLC-3, and PLC-5 controllers and enhanced processor versions. Loopback Diagnostics Support: Enables diagnostic testing when connected directly to the PCMK card. RJ45 Connector Type: Provides a reliable and standardized connection point for DH+ communication. Industrial-Grade Durability: Built for field use in programming, monitoring, and diagnostics. Remote I/O Capability: Supports scanner functionality through compatible PCMK cards. The 1784-PCM5 delivers the reliability and precision required for robust DH+ communication and PC-based programming in PLC-5 automation systems.
