1.7 DI/O Channels
Isolated Digital Input Channels
Isolated digital input has an open collector transistor structure with
voltage range 0V to 24V and input resistance of 2.4kΩ. Connection
between external signals and the PCIe-67432 is as shown in Fig A01.
Since input common junction can be common ground in the environ -
ment, digital input can be either a current source or a current sink.
