The transfer function for the output current will be as follows:
Iout = (I
4-20mA
Which produces 0A output current at 4mA and 100% rated output current at 20mA.

A 4-20mA current source is connected between Pin 4 (VPRG_VSOUR) and the return
Pin 18 (RTN_PRG, Refer to Figure 8-10.
The transfer function for the output voltage will be as follows:
Vout = (I
4-20mA
Which produces 0V output voltage at 4mA and 100% rated output voltage at 20mA.
