NOTE:
Inside the circuit board, there are bridges
already configured for the correct reading of
the digital and analogue inputs of the board.
Their setting must not be changed under
any circumstances.
Manufacturer settings of the bridges for the
200NDINFSC:
J31=1-2
J32=1-2
J21=1-2
J22=1-2
If 4-20mA:
J11=2-3
J12=2-3
Se NTC:
J11=1-2
