Descrição do produto

Level control relay for hole, with indication of “High Level”, “Lack of Water”, “Pump in Service” and “Thermal Shooting”.

The indications and how the level control relay for bore reacts (weapon and disarms), also allows 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

  • Control of level in conductive fluids by three probes (minimum, maximum and mass), with
    minimum level indication and protection.
  • Indication and protection of submersible electric pumps against lack of water.
  • Indication of “Pump in Service” and “Thermal Shooting”.

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).

After closing the contact pair (C-B), the “B.S.” (Service pump).

After closing the contact pair (C – DT) the LED “D.T.” (Thermal Shooting).
