I/O MTUS – S800 I/O – TU819

The TU819 is a 50 V compact module termination unit (MTU) for the S800 I/O system with 32 signal connections. The MTU is a passive unit used for connection of the field wiring. It also contains a part of the ModuleBus.

The TU819 MTU can have up to 32 I/O signals. The MTU distributes the ModuleBus to the I/O module and to the next MTU. It also generates the correct address to the I/O module by shifting the outgoing position signals to the next MTU.

Two mechanical keys are used to configure the MTU for different types of I/O modules. This is only a mechanical configuration and it does not affect the functionality of the MTU or the I/O module. Each key has six positions, which gives a total number of 36 different configurations.
