The TU810/TU810V1 is a 16 channel 50 V compact module

termination unit (MTU) for the S800 I/O. The MTU is a passive unit

used for connection of the field wiring to the I/O modules. It also

contains a part of the ModuleBus.

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.
