Description :

This device is used to detect 4mA-20mA signal equipment. It can simultaneously detect two devices with 4mA-20mA output signal. It uses SX1276 wireless communication module.The R718KA2 can detect the 4mA-20mA signal and add the detection signal data to the gateway to display the collected data in the gateway.

Typical applications for 4 mA to 20 mA products are sensing and instrumentation measurement applications. The signal current of general instrumentation is 4-20mA, which means the minimum current is 4mA and the maximum current is 20mA. There are many kinds of sensors in the industrial field that can be converted into 4~20mA current signals. This device converts the 4mA-20mA signal into an appropriate detection signal through the operational amplifier, and then samples the current value through the module ADC sampling.
