Description

The ABB TK850V007 (Order Code: 3BSC950192R1) is a specialized CEX-Bus Extension Cable designed specifically for the ABB AC 800M controller series and its associated S800 I/O system. This pre-assembled, shielded cable serves as the critical physical link for the CEX-Bus (Controller Extension Bus), facilitating high-speed, deterministic communication between the central controller unit (PM85x/PM86x) and the local or distributed S800 I/O stations. With a precise length of 0.7 meters, the TK850V007 is optimized for compact rack configurations where the I/O base units are mounted in close proximity to the controller or communication interface module (CI85x/CI86x). Its robust construction ensures excellent signal integrity, minimizing electromagnetic interference (EMI) in harsh industrial environments. Note that proper termination using the TK851 bus terminator is required at the end of the bus segment when using this cable.

Application Scenarios

A food and beverage processing plant was upgrading its packaging line control system using an ABB AC 800M controller. The new design required a compact S800 I/O station mounted directly adjacent to the controller cabinet to minimize latency for high-speed counter inputs. Engineers selected the ABB TK850V007 (3BSC950192R1) to connect the controller’s CEX-Bus port to the first S800 base unit. The 0.7m length was perfect for the tight space, eliminating excess cable clutter that could impede airflow or maintenance access. During commissioning, the TK850V007 provided a stable, noise-free connection, allowing the high-speed packaging sensors to communicate flawlessly with the PLC. This reliable link ensured precise synchronization of the fillers and cappers, preventing product waste and maintaining line efficiency.
