The National Instruments PCI-6111 is a high-performance multifunction data acquisition (DAQ) device designed for simultaneous sampling and versatile applications in industrial automation and control systems. Offering robust features, the PCI-6111 includes two analog inputs with 12-bit resolution, capable of sampling rates ranging from 1 kS/s to 5 MS/s. This device also provides two analog outputs with 16-bit resolution, supporting a maximum update rate of 4 MS/s for a single channel and 2.5 MS/s for dual channel operations. Additionally, it features eight channels of digital I/O compatible with TTL and CMOS signaling, along with two 24-bit counters for accurate event counting and timing functions.

The PCI-6111 is equipped with overvoltage protection up to ±42 V on all channels, ensuring reliable operation across diverse applications such as automotive testing, sonar, radar, and ultrasound measurements. With a 2,048 sample FIFO buffer, the device supports various data transfer methods, including interrupts, DMA, and programmable I/O. Enhanced by National Instruments' Real-Time System Integration (RTSI) bus, the PCI-6111 allows for precise synchronization across multiple DAQ devices within the same system, improving the overall measurement integrity.

The device's MITE bus interface chip facilitates easy configuration and calibration, eliminating the need for jumpers or switches. Coupled with the DAQ-STC system timing controller, it also provides maximum timing resolution of 50 ns and supports three timing groups. For software integration, the PCI-6111 is compatible with the NI-DAQmx driver and the Measurement & Automation Explorer configuration utility, streamlining setup and operational functionality. The unit is housed in a compact form factor of 12.3 x 4.2 inches and requires a power supply of +5 VDC at 2.0 A. Supported by a three-year warranty, the PCI-6111 is an excellent solution for comprehensive data acquisition requirements.
