Sensor network with module architecture

The principles of operation and peculiarities of the implementation of the device that performs both functions of the receiver of the 4-20 mA interface and the functions of the 4-20 mA interface transmitter, powered by the loop current of this interface are considered. This device is used for the creation of sensor networks, for measuring the parameters of the state of complex technical objects and for the remote transmission of the received data. Key words and phrases: sensor networks, current loop, 4-20 mA interface
