HART Multiplexer System KFD*-HM*-16
System Description
3.4.2 Mounting Integrated in the Process Control System
The multiplexer master and multiplexer slaves are connected to a termination board.
The termination board forwards the signals to the process control system via screw terminals
and system cables. The termination board establishes the connection to the connected
multiplexer masters and multiplexer slaves in parallel or series. The termination boards are
specifically tailored to the individual process control systems.
