MODBUS Water Leak Detection Controller

1. Stable and reliable: SPD-WL01-PRO uses high-quality industrial-grade electronic components to ensure high detection sensitivity and reduce false alarms caused by various external factors, while also ensuring long-term working stability. The controller has unique anti-surge protection function and provides 1 set of leakage alarm relays.

2. Easy to operate: There is an external 2-digit 4-position DIP switch on the SPD-WL01-PRO controller panel. Users can select different response sensitivities according to the level requirements of the detection environment (the adjustment range is within 1cm-20cm of the cable length). At the same time Users can easily select the relay output mode (NO, NC) through the external DIP switch. It is suitable for standard industrial modules and DIN rail installation. All on-site wiring can be easily completed through wiring terminals. When a leak occurs, the relay will act, the leak indicator light will light up, and the built-in buzzer will sound. After the danger is eliminated, the device will automatically reset and return to normal status without manual on-site operation.

SPD-WL01-Pro working with non-location water leak sensing cable, it's used to detect water leakage, mostly used in server room, data center air conditioner water leak monitoring, pump water leak, and other applications.

Q: How does the controller work?

A: It works with a water leak sensing cable. once the cable contact water, it will be short circuit and controller will receive the water leak signal. Then controller will give a RS485 output and 1 set NO/NC relay output to the third device (siren or a monitoring system).

Q: Does it support MODBUS protocol?

A: Yes, it support MODBUS-RTU protocol.

Q: Can it give leakage distance?

A: No, this is non-location type water leak detector, only leakge alarm, no distance can be detected.
