Temperature : Sensors are platinium resistor RTD : PT100 with 4 wires. You can connect them directly to the iMinilide. We use four wires for the calibration. With 4 wires you can extend the sensor with 10 meters or 100 meters of cable and you have the same measure. The length of the cable has no effect on the value.
Contact : Voltage free contacts open or closed. You can set the level for the alarm and for the display string.
Other : 4-20mA input. With the Kit 4-20mA, you can connect all sensors which use this output on the market like humidity level or pressure. The iMinilide may supply power or not the sensor with a 24V Dc internal power supply.
