the required action, such as actuate a relay.

This connection option requires the fewest free lines in the trailing cable
and avoids voltage drops due to excessively long lines. The controller can
be installed outside the lift where it is protected in a place, such as the
engineering room.
The reader is not powered via the controller. Instead, it is connected to the
existing power supply in the lift cab, which provides electricity for lighting,
doors and other elements. The voltage may need to be converted with a
power supply unit, so that it is within the specified voltage range for the
SmartOutput module and reader (see
supplied to the individual components do not need to be identical. It is thus
possible to operate the controller with 12 V while the reader in the lift is
operated with 24 V.
Common earth connection
In this specific case, four lines are also needed to supply power to the cab.
