3.4 Isolated Digital Input Channels
The isolated digital output is an open collector transistor output.
The input accept voltage form 5V to 24V and input resister is
1.2K Ω. The connection between outside signal and PCI-7230 is
shown below.

3.5 Isolated Digital Output Channels
The connection of isolated-digital output is shown as following
diagram. An external voltage source (5~40VDC) is necessary to
power the internal isolated circuits, and it is connected with pin-
19 of CN2. When the isolated digital output goes to high, the
sink current will be from VDD.
