Digital Channels
The PCI-PIO features two digital ports with 16 inputs or outputs each. The lines are bidirectional. The
direction is set to input or output in groups of 8 via software.

•
The digital inputs and outputs are protected by serial resistors. Input voltages beyond the
permitted voltage range of 0V..5V can damage the device.
•
At PC start, port A is set to input, port B to output.

5V Auxiliary Voltage
The PCI-PIO provides an auxiliary voltage (e.g. for sensor supply) at pin 9, 28 of the 37-pin D-Sub
female. The 5V DC output (100mA) is protected by a fuse (multifuse). In case of overload, it is
sufficient to interrupt the power supply (turn off PC or disconnect the consumer load). After app. 1
min., the multifuse will be regenerated.
