ZAS K2 is a complete set of devices, consisting of the active isolating relay ATR U2 and the magnetic contact MKW 1.

The set is ideally suited for supply air monitoring when operating extractor hoods in accordance with §4 of the Firing Ordinance (Germany).

 

The active isolating relay ATR U2 enables mains voltage consumers to be switched very easily using extra-low voltage contacts. There is no need for a power supply unit, as the relay generates the necessary control voltage (24V DC PELV) internally. In conjunction with the MKW 1 magnetic contact, it is thus possible, for example, to implement the supply air monitoring (frequently required for enclosed rooms when operating exhaust fans) with little effort. Due to the change-over contact the ATR U2 is extremely versatile.

 

Applications
Window monitoring in connection with fume hoods, signal circuits, alarm messages, door monitoring, theft protection, etc.
