This board allows converting a 4..20mA signal into an output voltage
Protection against reverse polarity
By means of the "ZERO" potentiometer we make the value of the minimum current 0mA or 4mA coincide with the minimum value of voltage at the Exit. Normally 0 volts
By means of the "SPAM" potentiometer we match the maximum value of the current at the output with the maximum value of the voltage at the output, As we are normally interested in 10V, but it can also be 3.3V or 5V for example
Jumper configuration:
4-20mA:
range 0-2.5 V: pin 1, 2 on pin 3, 4
range 0-3.3 V: pin 1, 2 off pin 3, 4 off
range 0-5.0 V: pin 1, 2 on pin 3, 4
range 0-10.0 V: pin 1, 2 on pin 3, 4 off
0-20mA:
0-3.3 V range: pin 1, 2 on pin 3, 4
0-5.0 V range: pin 1, 2 on pin 3, 4
0-10.0 V range: pin 1, 2 to pin 3, 4 off
Power supply: 7..36V (if 10V is needed at the output, the power must be greater than 12V)
Dimensions: 42 x 25.20 mm
