National Instruments 783633-01 Multifunction I/O Module

The National Instruments 783633-01 (PXIe-6365) is a high performance multifunction I/O module designed for versatile data acquisition and control applications. It supports both analog and digital inputs and outputs along with four 32-bit counter/timers capable of handling PWM, encoder, frequency measurements and event counting. This makes the module suitable for a wide array of tasks from basic data logging to more complex test automation setups. The 783633-01 module offers 72 differential or 144 single ended analog input channels with a 16 bit resolution that ensures high precision data acquisition. It can achieve a maximum single channel sample rate of 2 MS/s while the multi channel sample rate caps at 1 MS/s. These rates are ideal for applications requiring high speed data capture. The device’s input range spans from ±0.1 V to ±10 V. The module supports DC input coupling that ensures that only the desired signals are captured without unwanted AC noise interference.

The NI 783633-01 provides two channels for analog output with 16 bit resolution and each can update at rates of up to 2.86 MS/s. The output range is adjustable between ±10 V and the outputs are coupled with DC to maintain signal integrity. This feature is crucial for applications requiring precise control of analog signals such as in feedback loops or signal generation. This I/O module includes advanced timing and synchronization capabilities powered by NI-STC3 technology that enables independent analog and digital timing engines. This allows for complex retriggerable measurement tasks and synchronized operations across multiple channels. The onboard scan list memory supports up to 4,095 entries that facilitating complex scanning routines and large scale data collection.

The model’s digital I/O functionality is robust and features 24 channels with programmable direction control. The device supports static digital input/output and timing input/output with debounce filter settings ranging from 90 ns to custom intervals. The model’s physical characteristics include a standard 3U PXI form factor that makes it compatible with various PXI Express or PXI Express hybrid slots. The 783633-01 module is equipped with three 68-pin VHDCI connectors that provide ample connectivity options for diverse applications. The module ensures reliable operation in demanding environments with a power requirement of +3.3 V and +12 V and current limits specified for different terminals.
