Digital actuation connection
dual channel digital input and
single channel digital output.
The digital output stage can drive resistive, capacitive and inductive loads with a max. output capability of 2.5 A
per channel and a maximum operating voltage of 48 V; the input stage can be used to read sensor signals (0-24
V) or for feedback signalization related to the digital output status (as the operating voltage is 48 V, the feedback
to the
has to be scaled according to the maximum input voltage reported in the datasheet).
Load actuation and feedback detection can be enabled via J2 (three ways) and J14 (two ways) screw connectors.
The picture below shows a connection example of a proximity sensor with feedback in the range of 0-24 V and an
electrovalve (a generic load can be used as well) as load on the actuation stage.
