ABB TU837V1 3BSE013238R1 S800 I/O Extended Module Termination Unit (MTU)

Description

The TU837V1 3BSE013238R1 connects field instrumentation to the internal ModuleBus with 24 screw terminals, optimized for three-wire connections (signal, return, ground/shield). This "Extended" MTU variant reduces the need for external marshalling blocks, simplifying cabinet layout. It features mechanical keying to ensure correct module installation and supports hot-swapping for quick maintenance without power or wiring disruption. Built for industrial use, the TU837V1 mounts securely on standard 35mm DIN rails.
