National Instruments PCI-6703

This section describes how to make connections for voltage and current outputs. The NI 6704 has both voltage and current outputs. The NI 6703 has voltage outputs only. A 68-pin cable such as the SH68-68-D1 cable is required. Figure 2-3 shows how to connect the voltage channel as a voltage 

output.

You can connect a floating load to your NI 6703/6704 device at the voltage output channel.Caution Because NI 6703/6704 devices are not electrically isolated from high voltages, a load with high common-mode voltages can damage the devices. National Instruments is not liable for any damages resulting from any such signal connections. 

The NI 6703/6704 device has a bipolar voltage range of –10.1 to +10.1 V. Maximum load current is ±10.1 mA for 16-bit linearity.

Power-On State

All voltage outputs are at their user-defined values to full accuracy within 1 s of power-on board reset. Before this time, the voltage outputs can float to unspecified values. Take this behavior into account when connecting external devices to the NI 6703/6704.
