Water Sensor Relay Switch Module, 9-12V DC

£29.99
Maximum quantity available reached.

This clever German manufactured device completes a circuit when the level sensor comes into contact with water. Great for pump switching and level detection. 

When the 2 sensor connections of the module come into contact with water, the built-in relay switches on. Sirens, other cutoff relays, etc. may be triggered with that.

Comes complete with instructions.

Technical data:

  • Operating voltage: 9 V DC voltage are ideal (max. 12 V DC), (only use a stabilised power supply)
  • Current consumption: "Ready": < 10 mA. If contact is made with water when the relay picks up: < 90 mA each with 9 V
  • LED displays: 1 LED for the indication of readiness “POWER”, 1 LED for the indication “ON”, if the relay switches on
  • Connections: via free cables
  • Approved cable length towards the water sensors: max. 5 m with normal cable, max. 100 m with shielded cable, if the shielding braid is connected with the negative pole of the distribution voltage
  • Dimensions: sealing case approx. 71 x 45 x 20 mm (without fastening lugs)
