KNX dimmer actuator 4‑channel Gira Dimmaktor REG KNX Secure 202500, 4 outputs

Gira Dimmaktor REG KNX Secure 4‑channel is a KNX dimmer actuator designed to integrate with KNX building automation systems and deliver dimming control for four independent lighting circuits. The device supports secure KNX communication and is suitable for both centralised and distributed installation scenarios in residential and commercial projects. It provides the functionality needed for timed scenes, group control and energy‑efficient lighting management while fitting into standard electrical installation practices.

Advantages

The 4‑channel KNX dimmer actuator offers independent control of four outputs, enabling flexible zoning and customised lighting setups. Secure KNX communication protects configuration and control messages on the bus. The actuator supports common dimming methods and integrates with KNX scene and group management, simplifying automation tasks. Its compact installation form factor allows mounting within distribution boards or installation boxes close to load circuits.

Key specifications

How to use

Install the dimmer actuator in accordance with local electrical regulations and the KNX system design, placing the unit in a distribution box or installation space near the controlled loads. Connect each lighting circuit to its dedicated output and attach the KNX bus to the device’s bus terminals. Commission the actuator using ETS or an appropriate KNX configuration tool, assigning group addresses, scenes and parameters such as dimming curves and load types. Verify secure communication settings if KNX Secure is required in the project.
