Active isolating relay


The active isolating relay 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.

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