National Instruments 783633-01

The National Instruments 783633-01 (PXIe-6365) is a high-performance multifunction I/O module specifically engineered for diverse data acquisition and control applications. This module features the capability to handle both analog and digital inputs and outputs, complemented by four 32-bit counter/timers adept at processing PWM, encoder signals, frequency measurements, and event counting. With up to 72 differential or 144 single-ended analog input channels, the module delivers 16-bit resolution, ensuring precision in data acquisition. It can achieve a maximum single-channel sample rate of 2 MS/s and a multi-channel sample rate of 1 MS/s, making it ideal for high-speed data capture tasks. The input range extends from ±0.1 V to ±10 V and incorporates DC input coupling to minimize AC noise interference, thus capturing only the desired signals.

In addition to its analog functionality, the 783633-01 provides two channels for analog output with a 16-bit resolution, capable of updating at rates up to 2.86 MS/s within an adjustable output range of ±10 V, while maintaining DC coupling for signal integrity. The module is built with advanced timing and synchronization capabilities enabled by NI-STC3 technology, which features independent analog and digital timing engines, allowing for complex retriggerable measurement tasks and synchronized operations across multiple channels. The onboard scan list memory supports up to 4,095 entries, facilitating intricate scanning routines and large-scale data collection.

The digital I/O capabilities are robust, featuring 24 channels with programmable direction control, supporting static digital input/output as well as timing input/output with user-defined debounce filter settings ranging from 90 ns to custom intervals. The National Instruments 783633-01 adheres to the standard 3U PXI form factor, ensuring compatibility with various PXI Express or PXI Express hybrid slots. It is equipped with three 68-pin VHDCI connectors, providing extensive connectivity alternatives for a range of applications. Designed for reliable operation in demanding environments, the module operates with a power requirement of +3.3 V and +12 V, with current limits specified for different terminals.
