Isolated Digital Output
If the external voltage source (5~30 V) is connected to each isolated digital output chan
-
nel and its isolated digital output turns on (500 mA max./ ch), the board's current will sink
from the external voltage source. The following figure shows how to connect an external
output load to the isolated outputs on UNO-137.
