Jola – KUR L4
Conductive relay in surface-mount housing, with potential-free make contact based on the quiescent current principle, with integrated connecting cable for supply voltage and controlled circuit. The KUR-L4 compact cooling ceiling controller is designed to measure the moisture between the printed conductors of a FTS/KO-1 film sensor and to switch the built-in output relay when a set sensitivity level is reached, thus permitting activation of an external solenoid valve. The cooling ceiling controller is in protective circuit design: the potential-free make contact is in quiescent current design – in other words, the relay is energized when the sensor is dry.
