HWg-WLD Relays are universal water floor sensors that detect flooding using a soak-detecting cable. The cable can detect small amounts of water and other liquids. The WLD Relay can be used separately with 12Vdc power supply and relay output (NO/NC) or as a sensor with Poseidon 2 environment monitoring unit connected via a 1Wire UNI bus (RJ11). The connected cable can be supplied up to 85m and can be extended up to 100m (185m in total) using 2m, 10 or 50m cables.
