電流開關 CS20-R
Current Relay CS20-R
The CS20-R is a low cost current relay designed for applica-tion that require an on-off indication of current. The relay will act while current is above the pre-set value，the current relay is recommended to be used for application where the operat-ing current is above 200mA。It is with 3 way selector that is used for to select the load circuit needed to be monitor.
The typical application is to monitor the work status of heat-ing element. When the load lose more than 1/3, the current switch will alarm, the alarm indicator will bright, and the con-tacts of relay will switch.
CS20-R電流開關，是一種低成本,專為只需要指示和告警電流有或無的場合應用的電流繼電器。電流值超過電流預置值時就能改變輸出繼電器的狀態(tài)，因此電流開關能應用于監(jiān)視電流為200mA以上的場合。帶有3路選擇開關，可用于選取需要監(jiān)視的負載回路。
典型的應用場合為監(jiān)視加熱元件的工作狀態(tài)。當加熱元件開路時，電流開關的告警指示燈會亮起，其輔助接點就會輸出告警信號；當組合式加熱元件中部分缺失，電流開關也會告警。
