Isolated Outputs - Advantech UNO-3072A User Manual

2.6.3 Isolated Outputs

Each of isolated output channels comes equipped with a Darlington tran-
sistor. All output channels share common emitters.
Please note that if an external voltage (5 ~ 40 V
lated output channel while it is being used as an output channel, the cur-
rent will flow from the external voltage source to the UNO-3072A/3074A.
Please take care that the current through each DO pin not exceed 200 mA.
Figure below shows how to connect an external output load to the UNO-
3072A/3074A isolated outputs. Please note that DO2 and DO3 may be
configured as output pins of Counter 0 and Counter 1.
Note: UNO-3072A/3074A provides built-in examples to show
how to deliver digital output functionality. Refer to con-
sole mode examples in
