ABB 3BSC950089R3 TK801V012 Modulebus Extension Shielded Cable – AC800M Controller Series
In a modern distributed control system, every millisecond of communication latency matters. When the Modulebus cable connecting your AC800M controller to its I/O modules fails or is absent, the entire process loop goes blind — operators lose real-time feedback, safety interlocks may trip, and unplanned downtime cascades across the production line. The ABB 3BSC950089R3 TK801V012 Modulebus Extension Shielded Cable is the precision-engineered link that keeps your AC800M backbone communicating without interruption.
The TK801V012 is ABB’s purpose-built shielded extension cable for the AC800M Modulebus architecture — one of the most widely deployed DCS platforms in power generation, oil & gas, pulp & paper, and chemical processing worldwide. As part number 3BSC950089R3, this cable is a genuine ABB spare that meets the exact impedance, shielding, and connector specifications required by the AC800M backplane, ensuring signal integrity across the full Modulebus segment length. Its global installed base and long product lifecycle make it a critical stocking item for any plant maintenance team running ABB automation infrastructure.

Frequently Asked Questions
Q: Is the 3BSC950089R3 the same as TK801V012?
A: Yes. 3BSC950089R3 is ABB’s catalog part number for the TK801V012 Modulebus Extension Shielded Cable. Both designations refer to the same product.
Q: What is the maximum Modulebus segment length supported?
A: Maximum segment length depends on the AC800M controller revision and number of nodes. Please consult ABB’s AC800M Hardware Configuration manual or contact our technical team for your specific topology.
Q: Can I use a third-party cable instead of the OEM TK801V012?
A: ABB does not recommend substituting third-party cables on the Modulebus. Impedance mismatches can cause intermittent communication errors that are difficult to diagnose. Using the genuine 3BSC950089R3 eliminates this risk.
Q: Do you offer expedited shipping for urgent plant shutdowns?
A: Yes. Please indicate urgency in your inquiry and we will prioritize sourcing and arrange express courier (DHL Express, FedEx Priority) to your site.
Q: What warranty applies to this part?
A: Warranty terms depend on part condition (new vs. tested/refurbished). Details are provided in the formal quotation. Please specify your requirement when inquiring.
