National Instruments PCI-6115 Multifunction I/O Device

The PCI-6115 is a Multifunction I/O Device from the S Series by NI. This device has two analog input FIFO buffer sizes available with different part numbers. Part number 778534-01 has 16 MS FIFO buffer size and part number 778554-01 has 32 MS FIFO buffer size.  This device offers four analog input channels. These analog input channels are differential. This model allows the user to input data for various measurement requirements. The instrument also has a simultaneous sampling capability, which is accompanied by a sampling rate of 10 MS per second for each channel. There are also two analog output channels with a maximum update rate of 4 MS per second. The PCI-6115 Multifunction I/O Device can be used in the following applications: IF digitization, radar, sonar, ultrasound, high-energy physics, 42 V automotive applications, and transient/ballistics measurements.

The NI PCI 6115 incorporates two counters. The counters both have 24 bit resolution. This feature makes the device suitable for various applications that involve stimulus or response calculations. These measurements require a high level of accuracy and synchronization capabilities. The value of absolute accuracy is 184 mV for the analog input channels. The device is powered through a BUS power interface. The PCI-6115 additionally incorporates eight digital channels. These channels are bidirectional. The dedicated A/D converters for each channel allow the user to reach quicker sampling rates for each channel, simultaneous sampling, and improved dynamic preciseness for transient or frequency measurements.

The NI DAQ PCI 6115 can be used with the NI-DAQmx driver, which simplifies the configuration and measurement procedure for the users. The instrument additionally has various event trigger applications available. This further enhances the operational capabilities of the PCI 6115 NI.
