电流开关 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电流开关，是一种低成本,专为只需要指示和告警电流有或无的场合应用的电流继电器。电流值超过电流预置值时就能改变输出继电器的状态，因此电流开关能应用于监视电流为200mA以上的场合。带有3路选择开关，可用于选取需要监视的负载回路。
典型的应用场合为监视加热元件的工作状态。当加热元件开路时，电流开关的告警指示灯会亮起，其辅助接点就会输出告警信号；当组合式加热元件中部分缺失，电流开关也会告警。
