This integrated design simplifies system deployment during installation and configuration and maximizes performances benefits.<\/p>\n<p>The power behind SCXI signal conditioning is your ability to create custom measurement solutions to solve your application. You can configure a system with just a few channels of I\/O or thousands of channels. SCXI offers modules for taking measurements from a wide variety of sensor and signal types, and it is designed so you can easily mix different signal types in one system.<\/p>\n<p>&nbsp;<\/p>\n<p>The\u00a0<strong>National Instruments SCXI platform<\/strong>\u00a0of high-performance signal conditioning encompasses the following:<\/p>\n<ul>\n<li>Modular signal conditioning platform for\u00a0<strong>M Series<\/strong>,\u00a0<strong>S Series<\/strong>, and\u00a0<strong>E Series<\/strong>\u00a0DAQ devices<\/li>\n<li>Multiplexer, matrix, and general-purpose switching<\/li>\n<li>Several chassis options; ideal for high-channel-count systems<\/li>\n<li>Direct sensor connectivity for easy system set-up<\/li>\n<li>Reconfigurable desktop, rackmount, and portable solutions<\/li>\n<li>Wide range of analog and digital conditioning options<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Many types of analog and digital signal conditioning modules form the basis of the\u00a0<strong>SCXI system<\/strong>. Analog input modules amplify, isolate, filter, and multiplex input signals from thermocouples, strain gauges, RTDs, thermistors, millivolt sources, voltage sources up to 250 Vrms, and current sources. You can mix and match any combination of\u00a0analog input,\u00a0analog output,\u00a0digital I\/O, and\u00a0switching modules\u00a0to meet your application requirements.<\/p>\n<ul>\n<li>Thermocouples<\/li>\n<li>RTDs<\/li>\n<li>Thermistors<\/li>\n<li>Strain gauges<\/li>\n<li>Pressure sensors<\/li>\n<li>Millivolt inputs<\/li>\n<li>Voltage inputs up to 250 Vrms<\/li>\n<li>Current inputs (0-20 mA)<\/li>\n<li>Frequency inputs<\/li>\n<li>Dynamic signals<\/li>\n<li>Voltage output<\/li>\n<li>Current output<\/li>\n<li>Isolated digital I\/O<\/li>\n<li>High-voltage digital I\/O<\/li>\n<li>Solid-state relays<\/li>\n<li>General-purpose switching<\/li>\n<li>Multiplexer switching<\/li>\n<li>Matrix switching<\/li>\n<li>Frequency counting<\/li>\n<li>Event counting<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>National Instruments<\/strong>\u00a0offers a variety of 32-channel analog input modules for SCXI, including the\u00a0<a href=\"https:\/\/www.apexwaves.com\/modular-systems\/national-instruments\/scxi\/SCXI-1100\"><strong>SCXI-1100<\/strong><\/a>,\u00a0<strong>SCXI-1102\/B\/C<\/strong>, and\u00a0<strong>SCXI-1104\/C<\/strong>. The programmable gain and filter settings are perfect for conditioning many types of millivolt, volt, and current inputs. Every module multiplexes the 32-channels into one channel of the DAQ device. You can add more modules if your application requires a greater quantity of channels. The\u00a0<strong>SCXI-1102B Amplifier Module<\/strong>, for example, can be controlled with the\u00a0<strong>SCXI-1600 USB Data Acquisition and Control Module<\/strong>.
