频率变送器(55-65)

the input signal is filtered and processed to convert into a standard dc voltage. this voltage is fed to a linear optocoupler whichprovides the required galvanic isolation. an optical feedback is used for improved linearity, response time and temperature effects.the output from the linear optocoupler is further processed to provide dc voltage/ current output.

the isolator with fast response time (10msec) is typically used in feedback control system.

in input dc current is chopped by the chopper to convert it into high frequency ac signal. this signal is fed to an isolating highfrequency transformer. the ac output current from the transformer is rectified and filtered to obtain load independent dc outputcurrent. as the transformation ratio is 1:1 the output current is identical in value to the dc input current.

输入信号被过滤，处理转而变为一个标准直流电压。这电压被喂一个线性变送器哪提供要求隔离电流。用于改善线性，响应时间，温度效应。产出从线性变送器更远的的过程提供直流电压/输出电流。隔音装置同快速响应时间(10msec)通常使用在反馈控制系统。

在输入直流电流被斩附近的的断路器兑换它到高频交流信号。

具体参数如下：
