Connectors

This section describes the connectors on the NI 8254R and includes pinouts

and signal descriptions for each connector.

2-Position Isolated Outputs Power Connector

The isolated outputs power connector on the NI 8254R accommodates one

power supply. The V terminal provides the isolated output circuitry (5 to

30 VDC) for the NI 8254R. The C terminal provides the common-mode

signal for the NI 8254R.

Figure 3-1 illustrates the isolated outputs power connector on the

NI 8254R.
