ABB TU838 3BSE008572R1 Extended Module Termination Unit

Description

The TU838 MTU (Module Termination Unit) is designed to facilitate the distribution of ModuleBus to I/O modules and subsequent MTUs in industrial automation systems. It plays a crucial role in generating correct addressing signals for I/O modules by shifting outgoing position signals to the next MTU.
