Isolated Outputs
Each of isolated output channels comes equipped with a Darlington tran-
sistor. All eight output channels share common collectors and integral
suppression diodes for inductive loads.
Please note that if an external voltage (5 ~ 40 V
DC
) 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-2050E. Please
take care that the current through each DO pin not exceed 200 mA.
Figure 2-6 shows how to connect an external output load to the UNO-
2050E’s isolated outputs.
Please note that DO6 and DO7 may be configured as Counter 0 and
Counter 1’s output pins, please refer to “Section 2.6” for detail.
