Product Description
The two-fold interface is a versatile solution for connecting switches, buttons, and LEDs in KNX systems. Designed for installation in wall boxes (Ø 60 mm, depth: 40 mm), this interface supports various configurations, such as switching, dimming, and controlling sunshades. Each channel can be individually configured as an input for potential-free contacts or as an output for LED control.
Applications
- Switching (on, off, toggle) on rising or falling edges
- Send value (8-bit, 16-bit, 16-bit floating point) on rising or falling edges
- Control after short or long button press, with adjustable period for long press
- Dimming with single or double button, including cyclical sending
- Control of sunshades with single or double button, such as raising/lowering blinds
- Scene control (1-bit or 8-bit) for switching between predefined scenarios
- Impulse counting with or without limit monitoring (8-bit, 16-bit, or 32-bit)
- Contact status transmission, e.g., for doorbell function
- Configurable conditions for sending after bus voltage recovery
Technical Specifications
- Bus voltage: 24 V DC (21…30 V via KNX bus)
- Maximum bus current: 6 mA (all channels as input), 14 mA (all channels as output), 5 mA (idle)
- Input voltage: approx. 29 V DC (bus voltage when contact is open)
- Input current: 0.2 mA DC per channel when contact is closed, peak 0.1 A at contact closure
- Input signal delay: 50 ms including contact debounce
- Output voltage: approx. 4.7 V DC via built-in 1.9kOhm resistor
- Output current: approx. 2.5 mA when short-circuited; LEDs must withstand a pulse load of 100 mA (tp 10µs)
- Operating temperature: -5 to +45 °C
- Storage temperature: -25 to +70 °C
- Relative humidity: 5% to 93%, non-condensing
- Dimensions (L x W x H): 42 mm x 42 mm x 8.5 mm, height around bus terminal 11 mm
- Installation: wall box installation, IP20 protection
- Pollution degree: 2 (according to IEC 60664-1)
- Overvoltage category: III (according to IEC 60664-1)
- Mechanical connections: screwless bus terminal Ø 0.6...0.8 mm, cable set for signals
- Fire load: approx. 530 kJ
Note
The interface complies with EN 50090-2-2 and EN 60669-2-1 standards, providing reliable performance in residential, commercial, and light industrial applications. No additional power supply is required, as the device draws its power from the KNX bus. Unused cable ends must be properly insulated, and connected cables can be extended up to 10 m using twisted pairs.
