3BSE013238R1 | TU837V1 | ABB | 250V 8-Channel S800 MTU

Product Description

Product Overview

The TU837V1 (Part Number: 3BSE013238R1) is a high-voltage Extended Module Termination Unit (MTU) engineered for the ABB S800 I/O system. It serves as the physical and electrical interface between field-side wiring and electronic I/O modules within the AC 800M and System 800xA control environments. Designed to handle up to 8 individually isolated channels, the TU837V1 supports high-capacity industrial signals up to 250 V and 3 A per channel. This passive unit manages both process power distribution and the ModuleBus backplane, ensuring deterministic communication across the I/O cluster through automatic position-based addressing.
