Allen-Bradley 1770-CD Data Highway Plus Twinaxial Cable

The Allen-Bradley 1770-CD (Blue Hose) provides a dedicated communication path for Data Highway Plus and Remote I/O networks. This shielded 150-ohm twinaxial cable ensures high-speed data integrity, resists industrial EMI, and connects PLC-5 or SLC 500 systems with maximum reliability.

The Allen-Bradley 1770-CD functions as the primary physical medium for establishing Data Highway Plus (DH+) and Remote I/O (RIO) industrial networks. This high-integrity twinaxial cable manages the transmission of critical data between PLC-5 controllers, SLC 500 processors, and distributed I/O racks. Because it features a specialized shielded design, the 1770-CD maintains signal purity in harsh industrial environments characterized by heavy electromagnetic interference (EMI).

By utilizing a dual-conductor configuration with a dedicated drain wire, this cable guarantees low-latency communication across long distances. The 1770-CD executes reliable data transfers at various baud rates, supporting the high-speed synchronization required for real-time automation. Furthermore, the rugged blue PVC jacket identifies the cable clearly within cable trays and conduits, while providing essential resistance to oil, chemicals, and abrasion.

Furthermore, the 1770-CD simplifies network installation through its flexible construction and standardized termination requirements. It effectively minimizes signal attenuation and crosstalk, ensuring that every node on the network receives clear and consistent data packets. Consequently, the Allen-Bradley 1770-CD delivers a robust and proven connectivity solution for legacy Rockwell Automation architectures, protecting the stability of the entire control infrastructure.
