Description
The National Instruments PXI-6238 Digital Multifunction I/O Module, with part number 779624-01, features 16 analog inputs with a resolution of 16 bits and a sampling rate of 1.25 MS/s, alongside 2 analog outputs.
It also includes 6 digital inputs and 4 digital outputs for versatile digital interfacing. The device supports bank isolation for enhanced signal integrity and auto-calibration to maintain accuracy over time and environmental conditions.
Calibration constants are securely stored on an onboard EEPROM that is non-modifiable, ensuring factory settings remain intact, while also providing a client modifiable area of the EEPROM for self-calibration constants.
The module is compatible with a wide range of sensors, including strain gauges, thermocouples, thermistors, angular encoders, linear encoders, and resistance temperature detectors (RTDs). Each module contains one analog-to-digital converter (ADC) that works with the internal multiplexers (MUX) to route one AI channel at a time to the ADC.
The inclusion of the NI Programmable Gain Instrumentation Amplifier (NI-PGIA) minimizes settling times for all input ranges, ensuring that the maximum resolution of the ADC is utilized for precise measurements.
