26 Operation Theory
example, voltage output channel 3 control the current source of
channel 3.
The output current range is programmable. The current range
control register controls all 8 current channels on the PCI-6308A.
There are three kinds of output current ranges. Refer to the follow-
ing table and Section 5.2.9 for programming the current range
using the _6308_I2V_Control function.
4.4 Isolated Digital Output
The isolated digital output is an open collector transistor output.
The isolation voltage between the isolated output and the host
power signals is 2500 Vrms
Figure 4-2: Isolated Digital Output
Note: Because the isolation DO is using open collector form, user
must add a series resistor on each DO channel to make the
DO works correctly.
Note: The Vsource can accept voltages of up to 24V.
