style="font-size:16px;font-family:宋体">DFM </span><span style="font-size:16px;font-family:宋体">系列数据采集模块是工业现场常用的导轨式隔离型模拟量采集单元，广泛应用于自动化测控、传感信号采集、设备数据集中监测场景，常见型号包含 DFM201 单路采集模块、DFM206 六路wn****输入模块、DFM218 八路采集模块、DFM113 测力采集模块等，属于分布式前端信号采集硬件。模块核心作用是把现场各类传感器输出的模拟信号，完成调理、AD 转换、隔离滤波，再通过工业总线把数字化测量数据上传至 PLC、工控机、触摸屏或者组态系统，是工业测控系统中传感器与上位系统之间的信号转换与数据传输桥梁。</span></p><h2><span style="font-family:宋体">、产品核心性能参数</span></h2><ol start="1" type="1" class=" list-paddingleft-2"><li><p><strong><span style="font-family:宋体">wn****信号输入能力</span></strong> DFM <span style="font-family:宋体">主流型号支持wn****输入，可通过软件参数配置切换信号类型，兼容热电偶、热电阻、直流电压、直流电流信号；部分专用型号如</span> DFM113 <span style="font-family:宋体">系列可支持称重、测力传感器信号采集，</span>DFM201A <span style="font-family:宋体">适配电位器信号采集，一套模块可以适配多种类型传感器，减少现场备件种类，降低选型成本昆仑</span>®<span style="font-family:宋体">工控。</span></p></li><li><p><strong><span style="font-family:宋体">测量精度与采集速度</span></strong> <span style="font-family:宋体">标准型号基本测量精度可达</span> ±0.2% FS<span style="font-family:宋体">，属于</span> 0.2 <span style="font-family:宋体">级高精度等级。单路型号转换周期***快</span> 0.1 <span style="font-family:宋体">秒（热电偶类型</span> 0.2 <span style="font-family:宋体">秒），多路版本根据通道数量自动分配采集周期，支持数字滤波功能，可通过参数调整滤波强度，抑制现场信号抖动，保证数值稳定输出。</span></p></li><li><p><strong><span style="font-family:宋体">全隔离抗干扰设计</span></strong> <span style="font-family:宋体">模块采用多通道相互隔离架构，<strong>输入、通讯、输出、馈电、模块电源之间电气隔离</strong>，绝缘电阻</span>≥100MΩ<span style="font-family:宋体">，绝缘耐压</span> 1000V AC<span style="font-family:宋体">。同时满足</span> IEC61000 <span style="font-family:宋体">电磁兼容三级抗干扰标准，可抵抗静电放电、电快速脉冲群、浪涌干扰，非常适合变频器、电机等强电磁干扰的工业控制柜内使用，能够阻断现场地环路干扰，避免信号漂移、数据跳变问题。</span></p></li><li><p><strong><span style="font-family:宋体">供电与功耗</span></strong> <span style="font-family:宋体">采用宽电压直流供电，供电范围</span> 10<span style="font-family:宋体">～</span>30VDC<span style="font-family:宋体">，适配工业标准</span> 24V <span style="font-family:宋体">直流电源；整机功耗小于</span> 4.8W<span style="font-family:宋体">，功耗低，长期连续工作发热量小，适合密集导轨多模块并排安装。模块自带隔离传感器馈电输出，可直接给现场两线制传感器供电，无需额外单独配电源，简化现场接线施工。</span></p></li><li><p><strong><span style="font-family:宋体">通讯性能</span></strong> <span style="font-family:宋体">标配隔离</span> RS485 <span style="font-family:宋体">通讯接口，支持</span> Modbus-RTU <span style="font-family:宋体">标准工业协议，也可切换</span> TC-ASCII <span style="font-family:宋体">协议；波特率可在</span>

style="font-family:宋体">楼宇能耗监测、中央空调系统，采集管道温度、水压、风量信号，接入楼宇自控系统；配电室、机房温湿度采集，实现远程监控。</span></p></li></ol><h2><span style="font-family:宋体">三、模块优势总结</span></h2><p>DFM 数据采集模块***大特点是通用性强、隔离可靠、安装简单，wn****输入可以灵活适配不同传感器；Modbus 协议通用性强，几乎所有工控系统都可以对接。模块把模拟信号就地数字化，减少长距离模拟传输缺陷，有效提升工业测控系统稳定性。在中小型自动化项目、多点传感采集项目中，相比 PLC 自带 AI 模拟量模块，DFM 分布式采集方案布线更简单，抗干扰能力更强，项目成本更可控。</p><p><br/></p> <div class="blank30"></div> <!-- tag --> <div class="blank10"></div> 标签： <a
