ABB TBU810 Terminal Base Unit 

Functional Description

The Termination Base Unit (TBU810) is a passive base unit used to house the modules. It contains the power

and field /O terminals, Profibus communication connectors, serial interface ports, redundant communication

ports, and relay output ports.

In a redundant configuration two TBU810's are mounted side by side and connected together. This

arrangement provides the communication path for the pair of redundant modules.

The TBU810 can be mounted on a standard DlN rail. It has a mechanical latch that locks the TBU810 to the

DlN rail. The latch can be released with a screwdriver.

The TBU810 has two mechanical locking devices that lock the modules in place.
