Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

控制器局部网CAN(Controller Area Network)属于现场总线的一种，是一种有效支持分布式控制或实时控制的串行通信网络，被公认为是最有前途的现场总线之一。 在工业控制系统中，电动执行器是电动单元组合仪表中一个很重要的执行单元。它由控制电路和执行机构两个在电路上完全独立的部分组成，可接收来自调节器的电控信号，将其线性地转换成机械转角或直线位移，用来操纵风门、挡板、阀门等...[详细]
