Pci-6704 is a multi-function PCI bus data acquisition module introduced by NI Corporation.

The PCI-6704 analog output device provides static or dynamic multi-channel analog output signals. The PCI-6704 analog output device allows users to create excitation-response, power control, deterministic control, and sensor/signal simulation applications. Analog output devices offer a variety of output resolutions, channel counts, and other onboard features. Therefore, the module can be used to replace a variety of instruments in the system, including independent proportional integral differential controllers, low-speed arbitrary waveform generators, and function generators.

National Instruments PCI-6704 analog output device

The PCI-6704 (Part number: 777306-01, 183689-01) is a 16-bit, 32-channel, static analog output device available in a variety of configurations for software-limited current and voltage applications. The board has 16 current outputs and 16 voltage outputs. Each output can be used simultaneously and individually by the user. The PCI 6704 also features eight digital I/O lines, each with an output of 0 to 20 mA or ±10 V. Part number 183689-01 is a dedicated hardware kit for PCI-6704.

This precise DC set point device for PCI can be used for many types of digital I/O and DC set point applications. With this tool, a user's PC can be used as a digital I/O system controller for industrial process monitoring, production testing, and laboratory testing. The PCI-6704 can generate analog functions, experimental stimuli, and can be connected to a variety of signal types, including leds, electromechanical relays, solid-state relays (optical isolation), and more. It comes with a 68-pin male I/O connector.

The NI PCI-6704 works in any standard CompactPCI box that complies with the PICMG CompactPCI 2.0 kernel specification. The device operates in a bipolar voltage range from -10.1 V to +10.1V, with a maximum load current of ±10.1mA for 16-bit linearity. With this device, the user does not need an externally connected floating power supply to complete the controlled current loop, as floating or grounded loads can be connected at the channel for current output. The control limit of the current circuit is 0.1 to 20.2 mA. All current outputs are kept within ± 1.1 mA (maximum) of the user-defined value for 0.5 seconds after power-on.

PCI 6704 runs with NIDAQmx driver software that is compatible with package/application development environments (ades) such as LabVIEW, LabWindows/CVI, or Measurement Studio.
