MDT SCN-LSD01.01 KNX Light Sensor / Controller with Constant Light Control, Flush-Mounted

Managing consistent lighting levels in rooms with changing daylight can be challenging. The MDT SCN-LSD01.01 addresses this by combining a light sensor and controller in one flush-mounted KNX device, enabling automatic constant light control for up to three independent channels.

Who is it for

This device is ideal for KNX installers and building automation professionals who need precise light regulation in offices, classrooms, or residential spaces. It suits projects requiring daylight harvesting and automatic adjustment of artificial lighting to maintain a set lux level.

Main features

• Constant light control with 3 independent channels
• Light measuring range from 0 to 1000 Lux
• Powered directly from the KNX bus (21-30V DC)
• Low current consumption of less than 10 mA
• Flush-mounted installation behind switches or in ceiling boxes
• Additional functions: day/night switching, scene control, threshold monitoring, offset correction
• Configuration via ETS software
