Description

The ABB TK801V006 is a specialized Module Bus Connection Cable designed exclusively for the ABB S800 I/O system. This 0.6-meter long, pre-assembled flat ribbon cable serves as the critical link between an S800 I/O Module (e.g., DI801. DO801. AI801) and its corresponding Terminal Unit (TU8xx) (e.g., TU810. TU811. TU830).

In the S800 architecture, the I/O module plugs into the backplane of the terminal unit, but the electrical signals for power and field wiring often require this specific interconnect cable to bridge the gap between the module’s internal bus connector and the terminal unit’s distribution points. The TK801V006 features high-quality shielding to protect against electromagnetic interference (EMI), ensuring data integrity in harsh industrial environments. Its connectors are keyed to prevent incorrect installation, and the 0.6m length is ideal for standard rack configurations where modules and terminal units are mounted side-by-side or in close proximity. Using genuine TK801V006 cables ensures compatibility, reliability, and ease of maintenance during module swaps or system upgrades.

Application Scenarios

During the commissioning of a new pharmaceutical packaging line using ABB AC 800M and S800 I/O, the integrator noticed intermittent communication faults on several digital output channels. Upon inspection, it was found that non-standard, manually crimped cables were used to connect the DO modules to the terminal units, leading to poor contact and signal noise. The team replaced these custom cables with genuine ABB TK801V006 (0.6m) pre-assembled cables. The robust shielding and factory-tested connectors of the TK801V006 immediately resolved the noise issues. The standardized length allowed for neat cable routing within the cabinet, improving airflow and making future maintenance (like swapping a faulty DO module) a matter of seconds rather than minutes.
