The iSN-101 series Liquid Leak Detection Module is a low-cost, intelligent liquid leak detection device that can be used to directly control Relay Output. No additional conversion module is needed and the iSN-101 can be easily integrated with a variety of monitoring systems to achieve remote alarm and remote device control. The iSN-101 Liquid Leak Detection module can be used to monitor double-core leader cable, with lengths of up to 500 meters, and can be used with both the sensor cable and its included water leakage probe (S3 modules include probe, otherwise sold separately) . If liquid is detected, the controller immediately activates the output relay - the normally open, normally closed passive output signal. The module can be easily integrated with other collection hosts connected to the network. The iSN-101 is suitable for real-time leak detection in critical locations, such as computer room base stations, warehouses, libraries, museums and industrial sites, and also for air handling equipment, refrigeration units, liquid containers, or pump tanks, etc., where there is a need to monitor any leakage of the equipment.
