MTN6720-0008 Schneider KNX 1-10V Dimming Module 8 Outputs Local Push Buttons LED Loads White DIN Rail

The MTN6720-0008 is an eight-output KNX dimming module that operates on the 1-10V control interface rather than by switching mains power directly. This distinction defines its application: it functions as a controller that communicates with dimmable electronic ballasts or LED drivers to set output levels, which aligns with commercial luminaires designed for central control systems.

Eight channels in a single DIN rail unit enable lighting riser control via KNX without requiring individual devices per circuit. Since mains switching occurs within the luminaire rather than at the module, board wiring consists of low-current control circuits and shared supply lines instead of eight separate mains dimmer outputs.

Integrated local push buttons allow manual operation of each channel during commissioning, streamlining the process of identifying output-to-fitting relationships and providing immediate value on installation projects.

Commissioning this module primarily involves establishing output-to-fitting relationships before programming begins, with local push buttons specifically designed for this mapping process. Once mapping is complete, attention must be given to dimming curves and minimum output levels, as 1-10V drivers exhibit different behaviors when switching off below specific control voltages.

Control wiring operates at low current levels, allowing cable routing within the same enclosure as other signal wiring. However, separation from mains conductors is recommended to prevent induced noise that could manifest as visible flicker.

When installed on KNX lines shared with other devices, line current budgets should be calculated, and channel behavior following bus voltage loss should be explicitly defined rather than relying on default settings.

• Commercial office floors: Primary application for luminaires with dimmable ballasts or drivers where lighting design depends on central control for daylight regulation and scene setting
• Retail and hospitality environments: Creation of layered lighting zones that can be reprogrammed as merchandising or layout requirements change
• Conference and lecture facilities: Multi-channel capability enables establishment of presentation, discussion, and cleaning states from a single control point
• Healthcare and laboratory spaces: Applied where controlled illuminance forms part of functional requirements
• Educational buildings: Links artificial lighting with daylight availability, with eight channels per unit accommodating projects requiring numerous individually controlled circuits without extensive panel space
