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.

External Signal

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.
