Special characteristic
Applications
The digital transmitter converts different signal sources to a load-independent current signal commonly found in process control systems. The output is the standard sensor line signal. It is a load-independend, 4 to 20 mA, DC signal which is superimposed with the digital HART® signal. The transmitter has extensive configuration options.
