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 VDC) is applied to an iso-
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-3072. Please
take care that the current through each DO pin not exceed 200 mA. Figure
2.7 below shows how to connect an external output load to the UNO-3072
isolated outputs.
Please note that DO2 and DO3 may be configured as output pins of Coun-
ter 0 and Counter 1 (please refer to section 2.7 for more details)
