National Instruments PCIe-6361 Multifunction I/O Device

The PCIe-6361 (Part Number: 781050-01, 193522C-03L), developed by National Instruments, is a multifunction DAQ (Data Acquisition) device designed to offer high-performance functionality for various industrial automation applications. It makes use of the high-throughput PCI Express bus, multicore-optimized driver software, and four 32-bit counters/timers in addition to digital and analog I/O.

Applications for the device range from simple data logging to control and test automation. With the help of the on-board NI-STC3 timing and synchronization technology, it offers sophisticated timing functions. This contains retriggerable measuring tasks and separate analogue and digital timing engines.

By using simple graphical programming software, users can create user-defined measurement systems for data logging using the PCIe-6361. For jobs like hardware validation, manufacturing floor monitoring, or scientific studies, it enables exact viewing, analysis, and data logging.

In control systems, the PCIe-6361 makes it easier to link sensors and actuators to a computer, allowing control systems to be made specifically for the needs of a certain application. It provides improved single-point I/O performance with its low-latency PCI Express interface, which is especially useful for applications that require deterministic operation.

The PCIe-6361 provides sixteen single-ended or eight differential analogue input channels with a 16-bit resolution. It offers multiple coupling options and input ranges, with a maximum sample rate of 1.00 MS/s for multichannel aggregate sampling and 2.00 MS/s for single-channel sampling. It also has high input impedance and all-analogue input channel overvoltage protection.

Analog output capabilities include two channels with 16-bit resolution, offering update rates of up to 2.86 MS/s for single-channel and 2.00 MS/s for simultaneous dual-channel operation. It supports various output ranges and coupling options, with low output impedance and overdrive protection.

For digital I/O and PFI (Peripheral Function Input), the PCIe-6361 provides a total of 24 channels, individually programmable as input or output. It features pull-down resistors, input voltage protection, and ground reference.
