The RS9219 configuration differential expansion protection instrument is a high-reliability differential monitoring protection instrument, which can monitor the range, alarm mode, relay working mode and direction of travel in the host computer, and record the differential expansion and alarm information in real time in the monitoring data field. The monitor adopts input and output isolation technology, strong anti-interference performance, can choose 4~20mA (or 1~5V) output, effectively reduce the distortion caused by long-distance transmission, widely used in the field of large rotating machinery involving expansion state monitoring and protection.
