This unique 24-bit front-end accepts bipolar voltage and current, resistance temperature detector (RTD) and thermocouple (TC) inputs. Built in Maxim Integrated&rsquo;s ultra-small Micro PLC form factor, the MAXREFDES67# performs with a effective resolution up to 22.3 bits with temperature error as low as &plusmn;0.1% across a range of -40&deg;C to 150&deg;C.<br /><br /> To enhance ease of use, the innovative system architecture switches all signals on board, meaning that the connector requires no jumpers or additional connections, regardless of the type of connection. In addition, the system features Maxim Integrated&rsquo;s Beyond-the-Rails feature in all signal-chain elements. Beyond the Rails reduces the need for large power supplies, allowing each element to accept large input voltages while running from a low-voltage power rail. <br /><br />The board features a micro USB connector for quick connection to a PC for evaluation. In addition, the board requires a 24V power supply, from a power supply or from the included AC/DC wall adapter. <br /><br /><strong>Applications:</strong> <br /> <ul> <li>Industrial control and

universal analog input for industrial applications. This unique 24-bit front-end accepts bipolar voltage and current, resistance temperature detector (RTD) and thermocouple (TC) inputs. Built in Maxim Integrated&rsquo;s ultra-small Micro PLC form factor, the MAXREFDES67# performs with a effective resolution up to 22.3 bits with temperature error as low as &plusmn;0.1% across a range of -40&deg;C to 150&deg;C.<br /><br /> To enhance ease of use, the innovative system architecture switches all signals on board, meaning that the connector requires no jumpers or additional connections, regardless of the type of connection. In addition, the system features Maxim Integrated&rsquo;s Beyond-the-Rails feature in all signal-chain elements. Beyond the Rails reduces the need for large power supplies, allowing each element to accept large input voltages while running from a low-voltage power rail. <br /><br />The board features a micro USB connector for quick connection to a PC for evaluation. In addition, the board requires a 24V power supply, from a power supply or from the included AC/DC wall adapter. <br /><br /><strong>Applications:</strong> <br /> <ul> <li>Industrial control and automation</li> <li>Process control</li> <li>PLC</li> </ul> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>High accuracy</li> <li>-10V to 10V &plusmn;20% voltage inputs</li> <li>-20mA to 20mA &plusmn;20% current inputs</li> <li>RTD and TC tested temperature range (-40&deg;C to 150&deg;C)</li> <li>Software-controlled input type</li> <li>24V input protection</li> <li>Isolated power and data</li> <li>Board and sensor calibration</li> <li>Micro PLC form factor</li> <li>Device drivers</li> <li>Example C source code</li> <li>Test data</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Board</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Applications Library</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6185/RD67_STM32F4_V01_00.zip" target="_blank">STM32F4 microcontroller (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Bill of Materials</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6185/MAXREFDES67_BOM_RA.pdf" target="_blank">Bill of Materials (BOM) for MAXREFDES67 (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Package</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6185/RD67V01_00.zip" target="_blank">Design Files for MAXREFDES67 (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6185/MAXREFDES67_SCH_RA.pdf" target="_blank">Schematic for MAXREFDES67 (pdf)</a> </div> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6185/MAXREFDES67_LAYOUT_RA.pdf" target="_blank">PCB Layout for MAXREFDES67 (pdf)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.maximintegrated.com/en/design/tools/cad-layout/gerber/MAXREFDES67_GERBER_RA.ZIP" target="_blank">PCB Gerber for MAXREFDES67 (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Simulation Model/CAD Models</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6185/MAXREFDES67_CAD_RA.zip" target="_blank">PCB CAD (PADS 9.0) for MAXREFDES67 (zip)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: resistance temperature detector, thermocouple, mcu, maxim, development_platforms_kits, reference_designs</div>
