Features
Signal Connection and Distribution:A passive unit that connects to field wiring,it includes part of the ModuleBus and distributes the ModuleBus to the I/O module and the next MTU.It also generates the correct address for the I/O module by transferring the output position signal to the next MTU.Mechanical Key Configuration:Two mechanical keys allow you to configure the MTU for different I/O module types.This mechanical configuration does not affect the MTU’s functionality.
Latching Device:Features a DIN rail latch for grounding.
Compatible Modules:Compatible with I/O modules such as the DI818 and DO818.
