This device is used for detecting 4mA-20mA signal, 0-24V DC ADC samples and dry contact features which employs SX1276 wireless communication module .

R718IJK can detect 4mA-20mA signal, 0-24V DC ADC sampling signal and dry contact input signal, and send the detection signal data to the gateway, and display the collected data in the monitoring platform.

SKU: R718IJK Categories: , , , , , ,
  • Using SX1276 wireless communication module
  • 2 ER14505 batteries AA SIZE (3.6V / section) power supply in parallel
  • Protection grade IP65
  • The base is equipped with a magnet, which can be attracted to iron objects
  • 4mA-20mA signal detection
  • Dry contact
  •    0-24V ADC detection (the red wire is connected to the positive 24V, the black wire is connected to the negative GND , be careful not to be reversed.)
