I/O connections and one ZP connection. The maximum rated voltage is 50 V and maximum rated current is 3
A per channel.
The MTU distributes the two ModuleBuses 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 mechanical 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 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.
