電流開關(guān) 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(guān)，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(yīng)用的電流繼電器。電流值超過電流預(yù)置值時就能改變輸出繼電器的狀態(tài)，因此電流開關(guān)能應(yīng)用于監(jiān)視電流為200mA以上的場合。帶有3路選擇開關(guān)，可用于選取需要監(jiān)視的負(fù)載回路。
典型的應(yīng)用場合為監(jiān)視加熱元件的工作狀態(tài)。當(dāng)加熱元件開路時，電流開關(guān)的告警指示燈會亮起，其輔助接點(diǎn)就會輸出告警信號；當(dāng)組合式加熱元件中部分缺失，電流開關(guān)也會告警。
