Description:
The TU891 MTU has gray terminals for field signals and process voltage connections.
The maximum rated voltage is 50 V and maximum rated current is 2 A per channel, but these are primarily constrained to specific values by the design of the I/O modules for their certified application.
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.S. I/O modules.
This is only a mechanical configuration and it does not affect the functionality of the MTU or the I/O module.
The keys used on the TU891 are of the opposite gender to those on any other type of MTU and will mate only with IS I/O modules.
