ABB | TU812V1 3BSE013232R1 | Compact Module Termination Unit

Product Description:

The TU812 is a 16 channel compact module termination unit. The TU812 has a 25 pin D-Sub connector for field signals and process power connections.The TU812/TU812V1 is a 50 V compact module termination unit (MTU) for the S800 I/O system with 16 signal connections. The MTU is a passive unit used for connection of the field wiring. It also contains a part of the ModuleBus.
The TU812/TU812V1 MTU can have up to 16 I/O signals. The maximum rated voltage is 50 V and maximum rated current is 2A per channel. 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. The configuration can be changed with a screwdriver.
