MTN6940-0000 Schneider KNX Master Extension Link Module Plug-In Coupling SpaceLogic Actuator Connection Unit
The MTN6940-0000 is a rail-mounted power-control instrument within the SpaceLogic KNX actuator family, designed for reliable commutation of electrical circuits in smart residential and tertiary buildings. This unit interprets standard KNX group telegrams and converts them into precise switching, dimming, or blind-travel actions on connected loads, serving as the critical link between intelligent control logic and physical electrical installations.
Featuring a modular, tool-friendly enclosure with clearly separated output terminals, bus connection port with polarity guard, and integrated programming button with bus-status LED indicator. The robust surge-tolerant relay or triac stages withstand repeated inrush cycles from modern electronic equipment, while the thermally balanced design ensures stable performance in sealed distribution enclosures without forced ventilation.
Environmentally conscious design utilizes halogen-free materials and carries comprehensive compliance documentation to streamline project approvals in demanding export markets.
