The Gira 201500 is a professional KNX dimming actuator designed for intelligent building automation systems. Built for DIN rail installation, this 4-gang dimming actuator is suitable for controlling and dimming multiple lighting circuits in residential, commercial and professional KNX installations.

Designed for use with the KNX bus system, the Gira 201500 allows connected lighting loads to be integrated into a smart building control environment. It is suitable for modern automation projects where lighting control, dimming, scene management and centralised building operation are required.

This unit provides four independent dimming outputs, each rated up to 225 W/VA, allowing control of up to four separate lighting channels. This makes it ideal for apartments, houses, offices, meeting rooms, hotels, showrooms, retail spaces and other installations where several dimmable lighting zones need to be controlled from a KNX system.

The actuator is designed for mounting in an electrical distribution cabinet on a standard DIN rail. Its compact 4-module width makes it suitable for professional panel installations where space efficiency and clean wiring are important.

As part of the Gira KNX system range, this dimming actuator is intended for use by qualified electricians and KNX installers. It can be configured using ETS software as part of a complete KNX installation, allowing flexible control functions depending on project requirements.

The Gira 201500 supports KNX Secure, providing enhanced protection for modern smart building installations. This makes it suitable for updated KNX systems where secure communication and reliable automation are important.

This product is ideal as a replacement unit, spare part, system upgrade or new installation component for KNX-based lighting control systems.
