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)
