Description
The WLD Relay 1W-UNI is a highly reliable water leak detector, designed for data centres, industrial sites, and security systems. It features dual output options: a relay output for external alarms and an RJ11 (1W-UNI) output for integration with HW group monitoring devices. The WLD sensing cable detects leaks along its entire length, ensuring early detection of even the smallest liquid presence.
Features
- Dual Output Options: Supports both relay (NO/NC) and RJ11 (1W-UNI) connectivity
- WLD Sensing Cable Compatibility: Detects water anywhere along up to 185m of cable
- Early Leak Detection: Responds to even a few drops of water, ethylene glycol, or other conductive liquids
- Standalone or Integrated Use: Functions independently with a 12V power supply or as a 1W-UNI sensor for HW group devices
- Reliable & Reusable: WLD sensing cable is re-usable after drying and cleaning
- No Bend/Twist/Grip Limits: Ensures long-term stability without damage from bending, twisting, or gripping
- Compatible with HWg Monitoring Ecosystem: Provides alerts, reports, remote monitoring, and API integration
