The National Instruments PXI-7842 PXI Multifunction Reconfigurable I/O Module is a versatile device designated by the part numbers 198219A-05L, 780338-01. This module falls under the category of PXI R Series and is specifically modeled as PXI-7842. It is engineered to facilitate complex and customizable I/O solutions.
At the heart of the PXI-7842 lies the powerful Virtex-5 LX50 FPGA, which enables the module to handle a wide range of data processing and control tasks. The module is equipped with 8 AI (Analog Input) channels, employing a Successive Approximation ADC (Analog to Digital Converter) with an input resolution of 16 bits. The A/D conversion time is remarkably fast at 4 μs, allowing for a maximum sampling rate of 200 kS/s and a small signal bandwidth of 1 MHz.
In addition to its impressive analog input capabilities, the PXI-7842 also features 8 AO (Analog Output) channels that support 16-bit, single-ended, voltage output. These channels can achieve a maximum update rate of 1 MS/s, with a voltage range of ±10V, enabling precise control over output signals.
For digital I/O, the module boasts 96 DIO (Digital Input/Output) channels, compatible with 3.3 V TTL and 5 V TTL logic levels. This extensive array of digital channels further enhances the module’s versatility, making it suitable for a wide range of applications in automated test, control, and data acquisition systems.
