National Instruments PXI-6238 Digital Multifunction I/O Module

The NI PXI-6238 Digital Multifunction I/O Module (Part Number: 779624-01) comes with features such as Bank Isolation, 16 AI (16 Bits, 1.25 MS/s), 2 AO, 6 DI, and 4 DO. Sourcing can auto-calibrate to correct displacement and adjust mistakes. The user can align the gadget to limit the AI and the errors caused by the drift of time and temperature at the time of execution. No outside circuit is vital; an inward reference guarantees high accuracy and solidness after some time and temperature changes.

Factory-calibration constants in this model are stored in an onboard EEPROM and cannot be changed. When the user self-adjusts the gadget, software stores new constants in a client modifiable area of the EEPROM. To restore a gadget to its initial industrial facility alignment settings, the software can duplicate the factory-calibration constants to the client modifiable area of the EEPROM.

In this model, sensors can produce electrical signals to quantify physical phenomena, such as temperature, force, sound, or light. Some regularly utilized sensors are strain gauges, thermocouples, thermistors, rakish encoders, straight encoders, and resistance temperature identifiers (RTDs).

The NI PXI-6238 Multifunction I/O Module has one analog- to-digital converter (ADC). The multiplexers (MUX) route one AI channel at a time to the ADC through the NI-PGIA. The NI programmable gain instrumentation intensifier (PGIA) is an estimation and instrument class intensifier that limits settling times for all information ranges. The NI-PGIA can open or lessen an AI signal to guarantee that the maximum resolution of the ADC is used.
