This relay box is used to connect up to four pressure sensors. A relay box can be connected by means of a special cable FA409...to the measuring amplifier with the channel division 4x temperature / 4x pressure measurement (MIS-202-PT) or 8x pressure measurement (MIS-202-PP).
Up to 4 pressure values can be measured in parallel in real time.
The special cable from the connection of the relay box to the measuring amplifier is available in different lengths for different installation possibilities.
