1.6.1 Analog inputs for linear sensors
To D1-15A series modules can be connected 0-10V or 0-20mA/4-20mA
linear sensors. Input channels can be configured individually as voltage or
current using jumpers from J15 to J20 (closed for current inputs).
For a 0-10V output sensor connection connect, for each set of three screws,
positive sensor signal to the screw called IN and the negative sensor signal
to the 0V one, as shown in figure 1.3.

For a current output sensor connection, it is necessary to distinguish 2
cases:
A) linear sensor supplied by the D1-15A module; supply the sensor
through the screw 24V and connect the sensor signal to screw
called IN (fig. 1.4A);
B) linear sensor esternally supplied; supply the sensor through an
external power source and connect its negative to the screw called 0V
and connect sensor signal to the screw called IN (fig. 1.4B).

module (case A) or by an external power source (case B)
