The ED-SxED input device from Zumtobel is a compact interface module for bus-controlled lighting and room management systems. It features four addressable inputs designed to integrate conventional switching and control units such as light switches, window or blind switches, motion sensors, time clocks, or other contact switches into a DALI-based system. The device function enables control of actuators within a room or a group of actuators, with input assignment achieved through addressing. The power consumption is 4mA, equivalent to the load of two DALI devices. The DALI input is voltage-resistant against 230/240V external voltage, ensuring safe integration into existing electrical installations.

Applications
This device is designed for use in modern building automation systems, particularly in offices, conference rooms, classrooms, or other spaces requiring intelligent control of lighting, blinds, windows, or screens. It enables the connection of conventional switching and button units to a digital control network, allowing existing installations to be adapted to intelligent room management without extensive renovations. Integration is performed behind a switch or button in a flush-mounted box with a diameter of 53 mm and a height of 15 mm.

Functions and Equipment in Detail
The four inputs can be configured according to application as a switching input, switching-dimming input, switching-changeover input, or as a blind/screen or window input. As a switching input, a short actuation of the connected button switches between the scenes 'Absent 0' and 'Present 1'. As a switching-dimming input, a short actuation switches the scene, while a long actuation triggers alternating dimming of the lighting. When used as a switching-changeover input, the scene 'Present 1' is activated by closing a contact switch at inputs T1/T2, while the scene 'Absent 0' is triggered by opening a contact switch at T3/T4. Continuous contact switches can be connected to the bridged terminals 'ON' and 'OFF'. For blind or screen control, actuation of a button at T1/T2 triggers raising, while T3/T4 triggers lowering to the end position or working position. For window control, T1/T2 opens the windows, while T3/T4 closes them to the end position. Each input is equipped with two terminals 'T>' and 'T<'.

Technology Explained Simply
The device operates via the DALI protocol (Digital Addressable Lighting Interface), enabling bidirectional communication between the control device and actuators. The DALI line serves simultaneously as power supply and data transmission, simplifying installation. The voltage resistance of the DALI input against 230/240V external voltage protects the device from damage due to accidental connection errors. Contact switches must be equipped with potential-free switching contacts and must be rated for at least 15 VDC. The connection terminals are designed for direct connection to the supply lines of the device.

Compatibility and Accessories
The device is designed for use with conventional buttons, switches, motion sensors, time clocks, and other contact switches that feature potential-free switching contacts. Integration is carried out into existing DALI systems, with control via the DALI bus line. It is designed for mounting in a flush-mounted box with dimensions of 53 mm diameter and 15 mm height. The housing is made of flame-retardant, halogen-free polycarbonate and is transparent, allowing it to be mounted behind a switch or button without affecting the visual design.

Mounting and Installation
Mounting is performed in a flush-mounted box with the specified dimensions. The device is installed behind a switch or button, with the DALI bus line screwed to the device's input. The connection terminals are designed for direct connection to the supply lines of the contact switches. Installation requires no additional power supply, as the device is powered via the DALI line.

Operational Advantages
The ED-SxED enables flexible and cost-efficient integration of conventional control units into a digital room management system. The addressability of the inputs allows individual configuration according to application, enabling centralized and automated control of lighting, blinds, windows, or screens. The use of flame-retardant, halogen-free polycarbonate ensures high safety and environmental compatibility. The transparent housing allows inconspicuous mounting behind existing switches or buttons.

Dimensions and Material
The device measures 41.2 mm (width) × 28.2 mm (height) and weighs 0.03 kg. The housing is made of flame-retardant, halogen-free polycarbonate and is transparent, allowing inconspicuous mounting behind a switch or button. Mounting is performed in a flush-mounted box with a diameter of 53 mm and a height of 15 mm.

Functions at a Glance
The four addressable inputs can be configured as switching input, switching-dimming input, switching-changeover input, or as blind/screen or window input according to requirements. Actuation of the connected buttons or contact switches results in different reactions in the room management system depending on the setting, such as switching between scenes, dimming the lighting, or moving blinds, windows, or screens. Configuration is done via addressing the inputs, enabling flexible control.

Material and Safety
The housing is made of flame-retardant, halogen-free polycarbonate, suitable for safe and environmentally compatible use. The transparent design allows inconspicuous mounting behind existing switches or buttons. The voltage resistance of the DALI input against 230/240V external voltage protects the device from damage due to accidental connection errors.

Application Scenarios
The device is particularly suitable for rooms requiring intelligent control of lighting, blinds, windows, or screens, such as offices, conference rooms, classrooms, or presentation rooms. Integrating conventional buttons into a DALI system enables gradual modernization of existing installations without extensive renovations.
