device.
Connectors
This section describes the connectors on the NI 8254R device and includes
pinouts and signal descriptions for each connector.
2-Position Isolated Outputs Power Connector
The isolated outputs power connector on the NI 8254R device
accommodates one power supply. The V terminal provides the isolated
output circuitry (5 to 30 VDC) for the NI 8254R device. The C terminal
provides the common-mode signal for the NI 8254R device.
Figure 3-1 illustrates the isolated outputs power connector on the NI 8254R
device.
