TH1-230/400 control relay for water level - Toscano

Liquid (water) level control relay for probes using a conductive system. This level control relay allows the control of the water level in a well or a tank. Adjustable sensitivity and dual voltage operation, the same relay can operate at 230Vac or 400Vac. The connection is made through an undecal base (not included in the supply), this facilitates assembly and subsequent maintenance. By having a sensitivity control, this relay is suitable for situations where there are particular circumstances (high humidity, considerable distance between probes and equipment, grounding capacity of the probe cable). In these cases, it is necessary to be able to reduce the sensitivity to avoid false relay activations.

It has a connection for 2 probes, maximum and minimum level. The relay has a switched output counting (NO/NC).

Note: The supply does not include the probes or the undecal base, only the relay.
