It terminates up to 32 signal channels and distributes the ModuleBus to the connected I\/O module and the following MTU.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the MTU generates the required I\/O module address by shifting outgoing position signals toward the next MTU. Therefore, the physical MTU position participates in the ModuleBus addressing arrangement.\u003c\/p\u003e\n\u003cp\u003eTwo mechanical keys configure the TU818 for different I\/O module types. Each key provides six selectable positions, producing 36 possible mechanical configurations. This keying mechanism provides physical configuration control and does not change the electrical functionality of the MTU or connected I\/O module.\u003c\/p\u003e\n\u003cp\u003eThe supplied data identifies the TU818 as a single I\/O configuration unit with a 50 V rating.

It provides field-wiring termination and ModuleBus distribution rather than performing active signal processing.\u003c\/p\u003e\n\u003cp\u003eQ: How many signal channels does the TU818 support?\u003c\/p\u003e\n\u003cp\u003eA: The TU818 provides 32 signal channels and uses a 40 pole screw terminal for process connections.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the two mechanical keys?\u003c\/p\u003e\n\u003cp\u003eA: The two keys configure the MTU for different I\/O module types.
