Bi-stable latching relay #1, max. 1-24 V DC/V AC,
1 Ampere. Security feature: The relay keeps its state even
in the case of loss of power. You can configure the
default state of the relay (open/close) via the DoorBird
App. These ports can be used to connect e.g. an electric
door opener. The device does not supply power to the
connected device. The power supply for the electric door
opener must be installed separately.
When wiring an electric door opener directly
to a door station, there is a risk that the
electric door opener could be tampered by
unauthorized third parties (e. g. by breaking
the door station and short-circuiting the
wiring of the door opener).
Therefore, we generally recommend the use
of a remote safety relay mounted indoors (e. g.
DoorBird I/O Door Controller A1081) for wiring
an electric door opener for a more secure
installation in your home.
