S800 I/O- TU811V1

The TU811V1 is a 8 channel 250 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.

Features and Benefits

  • Compact installation of I/O modules.
  • Up to 8 isolated channels of field signals.
  • Connections to ModuleBus and I/O modules.
  • Mechanical keying prevents insertion of the wrong I/O module.
  • Latching device to DIN rail for grounding.
  • DIN rail mounting.
