HART调制器

HART（可寻址远程传感器高速通道）是全球工业应用领域领先的通信协议之一，大部分智能现场设备、智能过程测量和控制系统均采用该通信技术。HART是全球标准，以及通过模拟、4至20mA传输线路发送和接收数字信息的双向通信协议。HART技术可同时传送4-20mA信号的数字信息，并且与许多ADI的专用工业4至20mA转换器相配套，例如AD5755、AD5422或AD5421系列。HART技术经实践检验，易于使用且极为可靠。它并未取代4至20mA硬连线通信，而是通信的补充模式，以远程诊断和系统故障排除的方式提供额外信息，在适当的场合增强系统的SIL（安全完整性）等级。ADI提供一系列的HART调制解调器和配套转换器，可一起使用来实现稳定、精确并经HART基金会注册的解决方案。
