Main Features
输入范围:4~20 mA
输入类型:mV、V、mA或热电偶
分辨率:16位
隔离电压: 3000 VDC
支持Modbus/RTU协议
断线检测功能
8路通用模拟量输入
ADAM-4019+是一个8通道的通用模拟量输入模块。该新模块在其前身ADAM-4019的基础上改善了一个4~20mA的输入范围,并增加了能源耗尽检测功能。它的混合输入范围设计支持对各个通道的单独配置,以便在应用中节省成本和空间。其他常用的输入范围有+/-10V,mV和电热偶,这些都很好地集成在该模块中。它还支持资源耗尽检测,以便任何传感器故障都能被提前检测到。为了 容易控制,ADAM-4019+不仅提供ADAM ASCII命令,而且支持Modbus/RTU协议,可满足不同应用的需求。
