National Instruments 778316-01 Analog Output Device 

National Instruments part number 778316-01 is an identifying part number for the PCI-6703 an Analog Output Device with 16 Voltage Output Channels all with 16 bit Resolution and a maximum output voltage range of ±10.1 V. This device serves as a fixed analog output device, designed specifically for software‑controlled voltage output applications. Users can connect either a floating or grounded load to the output channel of this device without the need for an external floating power supply to complete the controlled current loop. 

The current loop can be controlled within a range of 0.1 to 20.2 mA, maintaining consistency from 0 V to 10 VDC. As each channel shares a ground line with a voltage channel, the impact of the returning current from the current channel on the voltage being outputted on the voltage channel is limited. For example, if a user outputs 20 mA on a channel and returns that channel to the device along the mutual ground line in a link with an impedance of 0.1 Ω, the voltage output on the voltage channel sharing the ground line will drop by 2 mV. 

The part number 778316-01 provides user-defined power-up states, a range of ±10 V, 8 digital I/O lines, DC output coupling, and allows for independent, user-defined values for the power-on state. This instrument is compatible with various signal types, including LEDs, voltage and current excitation for precision transducers, electromechanical relays, and optically isolated, solid-state relays, as well as I/O module mounting racks. It supports integration with NI-DAQ 7.4 or later, .NET Languages without NI Application Software, LabVIEW for Windows, ANSI C without NI Application Software, Measurement Studio, and LabWindows/CVI for Windows. 

It features a 68-pin male I/O connector for connectivity. The NI device has physical dimensions of 3.9 x 6.9 inches. It is recommended to operate within a temperature range of 0 to 55 °C, while the storage temperature range is -20 to 70 °C.
