ML20 Location Water Leak Controller
ML20 Location Water Leak Controller Products Description
ML20 Location water leak controller can detect 1500m sensing cable. It’ll alarm by flash and sound once there are water leaks on the cable, and the leakage point will display on the LCD screen and the relays will be on automatically. Combined with the MOD BUS RTU protocol, ML20 makes it easy to integrate with the monitoring system. ML20 can be used as an independent alarm, also can be connected to another monitoring system. It’s widely used in the monitoring machine rooms, warehouses, museums, industrial, fields to realize real-time leakage detecting.

Installation
Note: In order not to damage the controller, please keep its original package, open it until ready to install it.
Installation place choosing
Choose a location where the module will be protected from the elements, temperature extremes, or heavy vibration. The ML20 is designed to be snapped onto a standard 35 mm DIN rail. Existing electrical or instrumentation cabinet-swith spare rail space make good mounting locations. It is also possible to install a small section of DIN rail directly on a wall or cabinet surface and mount the ML20 in any location as long as it does not create a tripping hazard or expose the ML20 to impact damage. The ML20 should be mounted within a 1200m wire run from the control system host. Contact the factory for methods to increase the wire run distance beyond 1200m.
