Product Description:

The TU842 MTU can have up to 16 I/O channels and 2+2 process voltage connections. Each channel has two I/O connections and one ZP connection.  The maximumrated voltage is 50 V and maximum rated currentis 3 A per channel.
The MTU distributes the twoModule Buses to each I/O module and to the next MTU. It also generates the correct address to the I/O modules by shifting the outgoing position signals to the next  MTU.

The MTU can be mounted on a standard DIN rail. It has a mechanica l latch that locks the MTU to the DIN rail. Four mechanical keys,two for each I/O module, are used to configure the MTU for differenttypes of I/O modules. This is only a mechanical configuration and it does not affectthe functionality of theMTU or the I/O module. Each key has six positions,which gives a total number of 36 different configurations.
