This device is used for detecting 4mA-20mA signal, 0-24V DC ADC samples, and dry contact features which employ the SX1276 wireless communication module. R718IJK can detect 4mA-20mA signal, 0-24V DC ADC sampling signal, and dry contact input signal, send the detection signal data to the gateway, and display the collected data in the monitoring platform.
