PXI-6260 - NI Multifunction I/O Module

Description

The PXI-6250 (Part Number: 779116-01) is a PXI Multifunction I/O Module created for unrivaled precision at quick testing rates. This high-speed M Series module incorporates advanced highlights, such as the NI-STC 2 framework controller, NI-PGIA 2 programmable intensifier, and NI-MCal calibration technology to expand execution and exactness. The NI PXI-6250 has a locally available NI-PGIA 2 amplifier intended for quick settling time at high scanning rates, guaranteeing 16-bit resolution even when estimating all channels at superior rates. This module also has a two year calibration interval, meaning it should be calibrated externally a minimum of every two years. When checking between channels with a similar input range, the settling time increments with the present step between the channels. If the user knows the normal input range of their signals, then they can aggregate signals with comparative expected ranges together in their scan list. The user should utilize signal conditioning accessories for voltage inputs over 10 V or sensor measurements. Buffered acquisition data is moved from the NI PXI-6250 Multifunction I/O Module’s onboard FIFO memory to a PC buffer by utilizing DMA or interrupts before it is transferred to the application memory. This PXI Multifunction I/O Module can be used with NI-DAQmx driver software, LabVIEW SignalExpress LE data-logging software, and the Measurement & Automation Explorer configuration utility. The digital lines on the PXI-6250 module can drive 24 mA for actuator and relay control. When the user clocks the module’s digital lines at 10 MHz, then they can utilize the lines for pulse-width modulation to control pumps, valves, lamps, fans, and motors. The NI PXI-6250 can also be utilized with NI Analog Output Devices for 64 or more loops. The standard 3U PXI device weighs 7.5 oz. It has a recommended operating temperature range of 0 ºC to 55 ºC, a storage temperature range of -20 ºC to 70 ºC, a non-condensing humidity range of 10% RH to 90% RH, operating and non-operating random vibrations of 0.3 grms and 2.4 grms respectively–all at a frequency range of 5 to 500 Hz.

Analog input module is a device used to collect and process analog signals, which is usually composed of analog input circuit, analog-to-digital converter (ADC), filter and interface circuit. The analog input circuit is responsible for converting the external analog signal into a voltage or current signal, and then converting the analog signal into a digital signal through an analog-to-digital converter, and finally filtering and enhancing the signal through a filter, and finally output to a computer or other control equipment for processing and analysis. Working principle 1. Analog input circuit: The analog input circuit is a key part of the analog input module, which is mainly responsible for converting the external analog signal into a voltage or current signal. Common analog input circuits include resistance divider circuit, current voltage circuit and so on. The resistance divider circuit realizes the signal conversion through the series parallel combination of resistors, and the current voltage circuit realizes the signal conversion through the product of current and resistance. 2. Analog-to-digital converter (ADC) : The analog-to-digital converter is the core component in the analog input module, which is responsible for converting analog signals to digital signals. The analog-to-digital converter discretizes the input voltage or current into a series of digital values according to its magnitude, and converts the continuous analog signal into a discrete digital signal through a process of sampling and quantization. Common analog-to-digital converters include successive approximation analog-to-digital converters and integral analog-to-digital converters. 3. Filter: The filter is an important part of the analog input module, which is mainly used to filter and enhance the signal. The filter can improve the quality and stability of the signal by removing high-frequency noise and interference signals, thus improving the accuracy and reliability of subsequent processing. 4. Interface circuit: The interface circuit is the connection bridge between the analog input module and the computer or other control equipment, which is responsible for converting the digital signal into a form that the computer or other control equipment can recognize and process. Interface circuit usually adopts serial communication interface or parallel communication interface, and realizes data exchange and communication with computer or other control equipment through data line and control line.

Application field Analog input modules have a wide range of applications in industrial automation, such as: 1. Industrial production process monitoring: The analog input module can be used to monitor and collect analog signals such as temperature, pressure and flow in the production process, and feed back to the computer or other control equipment in real time for monitoring and regulation of the production process. 2. Environmental monitoring system: The analog input module can be used for the collection and processing of parameters such as temperature, humidity and gas concentration in the environmental monitoring system, so as to grasp the changes and anomalies of the environment in time. 3. Power system monitoring: The analog input module can be used for the acquisition and monitoring of voltage, current, power and other parameters in the power system in order to understand the operating status and load of the power system in real time. 4. Instrument testing: Analog input module can be used for analog signal acquisition and processing in instrument testing in order to evaluate and verify the performance and accuracy of instruments.
