Description

The TU811V1 3BSE013231R1 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.

FAQ

Q: What are the main differences between TU811V1 3BSE013231R1 and TU810V1 3BSE013230R1?
A: Voltage rating is the main difference: TU811V1 supports up to 250V, while TU810V1 is typically used only for low-voltage signals below 50V.

Q: Does TU811V1 3BSE013231R1 require a separate power supply?
A: The base itself is passive, but it requires a process voltage (e.g., 220V AC) to power the module via terminals.

Q: Can different module models be mixed in TU811V1 3BSE013231R1?
A: No. The mechanical key physically locks the base, allowing only specific types of modules to be inserted.

Q: Will a faulty TU811V1 3BSE013231R1 cause a bus failure?
A: Yes. Since the bus signals pass through the base, a failure may cause all downstream modules to lose connection.

Q: How many wire types of wiring are supported by TU811V1 3BSE013231R1?
A: It primarily supports single-wire wiring. For multi-wire wiring or common terminal distribution, additional power distribution terminal blocks are usually required.
