The TU818V1 is a 32 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.

Compact design reduces control cabinet footprint for more efficient use of space. Reliable Operation Designed for industrial-grade performance, ensuring long-term reliability. Easy Maintenance Simplified wiring and modular design make it easy to install, troubleshoot and replace.
