Migatron RPS-2100 material level controller

should rs -2100 is a single transducer device with 2 independent range control adjustment,LED indicator light,and form C relay output . these make the sensor well suited for high and low level control,or other applications,the two setpoints are required . the sensor also has a unique master and slave characteristics,make many identical units,used in close proximity to each other without crosstalk . for example,if three sensors are needed in a close area,then one sensor will act as the main sensor,the other two will act as slave sensors . this is via the board X enter 、X dewa GND realized by connection . a sensor ( host ) will pass X - OUT and GND the terminal sends a signal . these will be connected to the other two sensors ( slave ) of X IN and GND terminal . connect the sensor this way,all units will send and receive simultaneously . this will prevent crosstalk,and enable all three sensors to be used at the same time,close to each other .
