PCI-6023E -NI Multifunction DAQ

Description

The National Instruments PCI-6023E (Part Number: 777742-01, 185415B-01, 185415D-01) is a Multifunction I/O Device for PCI Bus Computers. This device comes featured with 16 analog input channels (8 x differential channels) with a maximum sampling rate of 200 kS per second, two analog output channels, 32 digital I/O lines, and a 100-pin connector. For time-related functions, the NI PCI-6023E uses a DAQ-STC timing controller. This controller contains three timing groups to general-purpose, analog input and analog output counter/timing functions. These three groups come with seven 24-bit and three 16-bit counters with up to 50 ns maximum timing resolution. The DAQ-STC brings various functions, such as seamless sample rate changing, equivalent time sampling, and buffered pulse generation. For an easy synchronization of several measurement functions to a common timing event or trigger, the NI PCI 6023E comes with an RTSI bus (Real-Time System Integration Bus). The RTSI bus incorporated is comprised of a ribbon cable and NI RTSI bus interface to route signals between various functions on as many as five data acquisition devices in a PC. The device is run using the NI-DAQ driver software which is compatible with other NI software packages or application development environments (ADES) such as LabVIEW, LabWindows/CVI, Measurement Studio, VirtualBench. Using any of the aforementioned ADEs greatly speeds up your development time. The PCI 6023E National Instruments can get coupled with an SCXI system as well. Thus, the user can acquire analog signals from strain gauges, RTFs, voltage sources, thermocouples, and current sources. Not only this, but the PCI-6023E also allows the user to acquire or generate digital signals for control and communications. This Multifunction I/O Device can operate in three input modes: NRSE, RSE, and DIFF. For multimode scanning, the user can program input modes on a per channel basis. The DIFF mode configured channels utilize two analog input lines, whereas channels configured in RSE or NRSE modes use one analog input line. The device weighs 4.1 oz., and measures 6.9 x 4.2 in. in physical dimensions.

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.
