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