Description
When a consistent quantity of variables must be made available to a distant location, instead of wiring each process variable signal with long individual connection lines up to the control room, it is advantageous to connect all input signals to a conveniently located field Multiplexer with short connections lines to the sensors. Data is then sent through a single communication line to the remote monitoring area. Multiplexer solutions are available both for Intrinsically Safe applications and for HART® compatible transmitters.
