Product description

Level control relay for hole or tank, indicating “High Level” and “Low Water”.

The indications and how the level control relay for hole evacuation reacts (gun and disarm), allows the protection of submersible electromagnets against lack of water. In addition, being a modular DIN-rail relay simplifies its installation. Advantage over 11-pin relays that require their docking station. Not only can it be used in standard electric switchboxes, it can also be used in modular boxes.


Applications

  • Level control in conductive liquids by three probes (minimum, maximum and mass), with indication and protection of minimum level.
  • Indication and protection of submersible electric pumps against lack of water.

Operation

Power the relay ( green led light on – A.1)

The “S1” contact will arm when the liquid level reaches the upper level probe (terminal S) (green LED lights up – “N.A.” high level).

The “S1” contact disarms when the liquid level drops below the lower level of the probe (terminal I) – turns off the green LED “N.A.” and lights red LED “F.A.” (lack of water).
