This input is compatible with any flow rate transmitter that provides a 4-20 mA output.
The impedance is 120 Ω. The input has a protection in order to limit the voltage applied to
the circuit.
In the event that the current transmitter is passive, for example a 2-wire transmitter, it is
necessary to power the current loop. It is done by connecting the transmitter to terminals 1
and 2.
If the current transmitter is active, the connection is between terminals 2 and 3.
