STEINEL KNX-S System Component DIM4 KNX-S Universal Dimming Actuator, 4-Channel, DIN Rail 089191

Managing multiple lighting circuits in a KNX building automation system often requires separate dimmers for each load type, complicating installation and programming. The STEINEL KNX-S DIM4 solves this by combining four independent universal dimming channels in one compact DIN rail module.

Who is it for

System integrators and electricians who need a reliable, space-saving dimming solution for mixed lighting loads in KNX installations, including residential and commercial projects.

Main features

• Four dimming channels, each rated up to 300 W/VA, with a total output of 1200 W/VA
• Universal dimming technology supports resistive, inductive, capacitive, and dimmable LED loads
• Leading and trailing edge dimming modes for optimal compatibility
• KNX bus connection for integration with building management systems
• Electronic overload and short-circuit protection
• Wide range of KNX functions: switching, dimming, scene control, staircase light function, status feedback, min/max brightness, soft start/stop
• DIN rail mounting (4 TE width) for easy installation in distribution boards
