Information About 1784-PCM4
The 1784-PCM4 is part of the Allen-Bradley PLC-5 communication accessory family and is engineered to link a PCMK/B card to DH+ or DH-485 network devices. Its construction includes a short segment from the card to the interface pod and a longer pod-to-processor lead for flexible routing inside control cabinets. The cable is commonly used to connect SLC 5/01, 5/02, and 5/03 processors or a 1747-AIC isolator for DH-485 communication. Typical usage includes programming, network access, and diagnostics where secure physical connectivity and strain-relieved cabling are required to prevent accidental disconnection.
Key Features:
- DH+ / DH-485 communication support: Enables connection to PLC-5 and SLC processors.
- 10.4-foot total length: Provides ample reach for cabinet or workstation setups.
- RJ45 processor connection: Ensures compatibility with supported processors and couplers.
- Designed for 1784-PCMK/B cards: Provides the required interface for portable programming hardware.
- Strain-relief wedges included: Reduces cable stress and prevents unintended disconnection.
- Segmented cable design: 7-inch PCMK card lead and 9.2-foot processor lead for flexible positioning.
- Secure installation: Uses sidebars on the connector for safe removal and proper attachment.
- Reliable communication link: Suitable for service, configuration, and maintenance tasks.
The 1784-PCM4 delivers the reliability and precision required for connecting PC-based communication cards to Allen-Bradley DH+ and DH-485 networks.
