LED KNX Controller Actuator 4CH DIN Rail

LED KNX Controller Actuator – 4CH DIN Rail Mount

The KNX LED controller actuator provides professional LED strip control within KNX building automation systems, the global standard for commercial and residential building control (ISO/IEC 14543-3). This DIN rail mounted 4-channel PWM actuator integrates directly with KNX bus networks, enabling centralized control of LED lighting alongside HVAC, shading, and security systems through a single standardized platform.

Each of the 4 output channels provides 4A at 12-48V DC with 16-bit PWM resolution for ultra-smooth dimming. The actuator supports KNX Data Secure for encrypted communication, meeting the security requirements of modern smart buildings. Programming is performed via ETS (Engineering Tool Software) with a comprehensive application database supporting all standard KNX group objects including switching, dimming, scene control, and HVAC integration.

The actuator includes 8 integrated logic functions (AND, OR, XOR, gate, staircase timer, delay) that execute locally without bus traffic, reducing network load. The 4TE DIN rail housing (72mm width) fits standard electrical distribution panels alongside circuit breakers and other DIN-mounted devices. A manual override button on each channel enables testing during commissioning without bus power.

Specifications

Target applications include premium office buildings with KNX infrastructure, luxury residential KNX installations, hotel chains with standardized building control, hospital and healthcare facilities, and airport or transportation hub lighting systems where KNX is specified as the mandatory building automation standard. The actuator enables seamless LED integration without proprietary gateways.
