AC actuator controls are your perfect solution if the application requires self-adapting control functions, data logging, a configurable interface or if valve and actuator are to be integrated into a Plant Asset Management System due to advanced diagnostic functions.
AC actuator controls are equipped with a parallel interface for free configuration and/or interfaces to fieldbus systems as used within process automation.
The diagnostic functions comprise a time-stamped event report, torque characteristics logging, continuous recording of temperatures and vibration within the actuator and, furthermore, counting the number of starts and motor running times.
Further to the basic functions, AC actuator controls offer a number of options to meet special demands. These include torque bypass to unseat valves if tightly seated or functions for extending operating times to avoid water hammer within pipelines.
With the development of the AC 01.2, particular emphasis was laid on user-friendliness and the ease of integration of actuators into the DCS. The large graphic display is used to perform menu-controlled programming of the actuator controls, optionally using AUMA CDT via wireless Bluetooth connection. For fieldbus connections, AC programming can be performed from the control room.

多种不同的现场总线系统已被广泛应用。在一个局部层面或某一特定现场应用中,参数设置准确性正不断被提高。AUMA执行器在全球各种工艺过程自动化控制现场中被广泛地应用,可与过程自动化工业中不同现场总线系统接口进行连接。
总之,AUMA设备具有连接其他数字量和模拟量信号传感器到现场总线的通信能力。
HART采用4 - 20 mA标准信号完成模拟数据传输。HART通信是在模拟量信号上叠加数字量信号。优势:HART协议实现了数字信号和模拟信号的同步传输。即在现有的4 - 20 mA模拟系统中完成数字信号的通信,因此,从现场设备中可随时读取过程参数和诊断数据。
HART基于主控制站 - 从站原理设计。可选的多支路HART拓扑结构基本与现场总线系统的线型结构一致。大部分情况下采用传统的4 - 20 mA点到点通信方式。
SIMA²主控制站是AUMA通过标准化现场总线系统控制和监测执行器的执行平台。该系统优化了主机和现场设备之间的通信,满足了应用现场的高效率要求。
简化了执行器和其它现场设备之间的配置、操作和资产管理。大量的冗余选项使得工厂可用性得到最大化。全面的诊断功能确保最佳的安装概览。
