STEINEL KNX-S componente de sistema UA24 KNX-S interfaz universal, 4 entradas binarias, montaje empotrado 089184

Integrating conventional switches, push-buttons, or potential-free contacts into a KNX building automation system often requires additional hardware and complex wiring. The STEINEL KNX-S System Component UA24 KNX-S solves this by providing four binary inputs that convert simple contact closures into KNX telegrams, enabling seamless control of lighting, blinds, and other functions.
