Voltage Output Connections
The PCI-1727U supports 12 channels of Analog voltage output. There is
only one output signal wire for each channel, as the voltage is referenced
to the common ground. A standard wiring diagram showing how to con-
nect a voltage output channel with a load as shown below.

V ” stands for voltage out-
put; “ I ” stands for current
loop. Voltage output and
current loop share the
same pin at AO8/9/10/11,
selectable by jumpers.
