In industrial control, it is often necessary to convert various non-electrical physical quantities such as temperature, pressure, speed, and angle into analog electric signals for transmission.Among them, the 4-20mA current signal is a widely used analog signal. This transmission mode has simple communication mode, strong anti-interference ability, and relatively reliable fault diagnosis function.
