Overview
DALI control output
DALI topology with sensors
The KNX/DALI gateway can control up to 64 ballasts per channel. In addition, selected DALI sensors that meet specifications from Siemens can be
commissioned together with KNX/DALI gateway. The maximum number of DALI devices is limited to the guaranteed rated current of 190 mA per
channel or to the maximum number of the DALI sensor type.

Switching off standby with DALI
Luminaires with electronic ballasts usually need a closed-circuit current, even when the lighting system is turned off or is in standby mode. This
energy consumption adds up, but can be conserved using the KNX/DALI gateway Twin plus: by automatically cutting off power to the electronic
ballasts. After the lighting is turned off and as soon as all electronic ballasts in the defined area are no longer needed for lighting, the ballasts
can be disconnected from the power supply via a command fom a switch actuator controlled for this purpose. If one or more luminaires are
in operation, the switch actuator first restores power to the electronic ballst, and the gateway dims the luminaire to the required brightness.
