Description
Schneider Electric KNX Pushbutton Interface: Enhanced Control and Status Monitoring in Your Smart Home
Benefits:
- Simplified Integration: Easily automate functions such as lights, shades, scenarios, etc. by connecting two or four conventional pushbuttons or dry contacts directly to your KNX system.
- Versatile Functions: Buttons can give commands such as on-off, dimming, shade control and script recall, while outputs provide status feedback via low-current LEDs.
- Enhanced Convenience: Check the system status at a glance with the help of LED indicators and easily configure button functions using the KNX software.
- Reliable Performance: The robust design with integrated bus coupler guarantees smooth communication and operation within your KNX system.
Features:
- Two or Four Inputs/Outputs: Available in 2-key (MTN670802) and 4-key (MTN670804) options to suit your control needs.
- KNX Software Functions: Supports on-off, dimmering, pitch control with position values, pulse edges, script recall and more.
- Condition Monitoring: Get visual feedback on system states and button presses by connecting low-current LEDs to outputs.
- Internal Signal Voltage: Eliminates the need for external power supply for connected buttons and LEDs.
- Easy Installation: It fits comfortably in a standard 60 mm switch box and the cores can be extended up to 7.5 meters for flexible placement.
- Fleece White Design: Sleek and modern aesthetics harmonize with any interior style.

Commercial Practices:
The KNX pushbutton interface can enhance control and monitoring in a variety of commercial environments:
- Office buildings: Automate lighting, curtains and ventilation based on room occupancy and calendars.
- Hotels and accommodation: Offer lighting and climate in guest rooms that guests can easily control.
- Public buildings: Enhance the user experience with accessible control buttons and status indicators.
The Schneider MTN670802 is a 2-channel pushbutton interface designed for KNX bus systems. The device generates internal signal voltage to integrate two conventional push-button or float contacts into the KNX system. It also has outputs for connecting 2 low current LEDs for status indication purposes. Technical parameters include Contact voltage < 3 V (SELV), < 0.5 mA contact current and a maximum output current of 2 mA. The unit is suitable for flush mounting in standard 60 mm switch boxes. On the software side, it offers extensive functions such as switching via 1 or 2 inputs, dimming, shutter control (including 8-bit position values). Pulse edges (1, 2, 4 or 8-bit), cyclic transmission, 8-bit linear regulator and counter functions are also available. The built-in 30 cm cable cores can be extended up to a maximum of 7.5 meters with twisted unshielded cable. The compact device dimensions are approximately 40x30.5x12.5 mm and has an IP20 protection rating.
