Isolated DI Connection

All isolated digital input channels accept voltages ranging from 10 to 30 V.
Additionally, every eight input channels share one external common pin (channels 0
~ 7 use EC0, channels 8 ~ 15 use EC1). The figure below shows how to connect an
external input source to the module's isolated inputs.
2.3.2

Isolated Digital Output

If an external voltage source (5 ~ 40 V) is connected to each isolated output channel
(On) and its isolated digital output is turned on (350 mA max./ch), the module will sink
current from the external voltage source. IDO modules provide GND pins for IDO
connection. The following figure shows how to connect an external output load to the
module's isolated outputs.
