Product Overview

The ABB TU835V1 (Order No. 3BSE013236R1) is a high-performance Extended Termination Unit designed for the ABB S800 I/O system. It serves as a critical interface component, bridging the gap between the field wiring and the electronic I/O modules. Specifically engineered for applications requiring higher power ratings or larger cable cross-sections, the ABB TU835V1 features the MTU50V (Modular Termination Unit 50mm Vertical) design. This “Extended” form factor provides the necessary physical space to accommodate robust wiring connections while maintaining the compact footprint characteristic of the S800 series.

As a fused termination unit, the 3BSE013236R1 integrates safety fuses directly into the base, offering enhanced protection for the connected field devices and cabling against short circuits and overcurrent events. This feature significantly improves the availability and safety of the automation system. The ABB TU835V1 supports redundant I/O configurations, making it an ideal choice for critical control loops in process industries where system downtime is not an option. Its robust construction ensures reliable signal transmission in harsh industrial environments, characterized by vibration, electromagnetic interference, and temperature extremes.
