National Instruments PXIe-6355 PXI Multifunction I/O Module

National Instruments created the multifunctional PXIe-6355 (Part Number: 783632-01) data acquisition (DAQ) device for use in industrial automation applications. It offers high-performance functionality via the PCI Express (PXIe) interface by integrating four 32-bit counter/timers, digital input/output (I/O), and analog I/O. It enables advanced timing activities such as independent analog and digital timing engines and retriggerable measurement jobs by utilizing the onboard NI-STC3 timing and synchronization technology.

Offering up to 40 differential or 80 single-ended analog input channels with 16-bit resolution and a maximum sample rate of 1.25 MS/s per channel, this DAQ device is adept at data logging. With features like a 100 dB CMRR and a guarantee of no missing codes, its integrated ADC provides accuracy and dependability. Furthermore, it protects all analog input channels from overvoltage.

For control systems, the PXIe-6355 enables users to connect sensors and actuators to build customized control systems. Users can accomplish high-performance single-point I/O operations with low-latency PCI Express bus connectivity. Sensor measurements, setpoint comparisons, and output signal updates are made easier by the device when used in conjunction with LabVIEW and NI-DAQmx driver software. Perfect for motor control applications, its four counter/timers also allow pulse-width modulation and quadrature encoder measurements, among other functions.

The device provides hardware-timed digital I/O, counters, and timers on a single platform for use in test automation applications. Accuracy and efficiency can be improved by simply synchronizing acquisition or generation across several subsystems with the help of NI-DAQmx software. Moreover, the PXI Express backplane facilitates the synchronization of many PXIe-6355 devices, guaranteeing smooth expansion and scalability.

Analog triggers are another feature of the PXIe-6355 that enable accurate triggering based on analog input conditions. Users can precisely set trigger conditions for a variety of applications with a 3.4 MHz bandwidth and 16 bits of resolution.

The device provides two channels with a maximum update rate of 2.86 MS/s and 16-bit resolution for analog output. Low output impedance and overdrive protection are two of its qualities that guarantee high-precision output.

In digital I/O operations, the PXIe-6355 provides reliable performance with positive/negative threshold levels and low input/output currents
