    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.
