MDT KNX binary input, 16-channel, potential-free, DIN rail mount

MDT Binary Input – Versatile status query for your KNX installation

The MDT binary input enables the precise detection and processing of state changes in your KNX installation. With up to 32 inputs and various options for potential-free contacts or voltage inputs (24V / 230V), it offers maximum flexibility for a wide range of applications – from integrating pushbuttons and switches to monitoring door and window contacts.

Key features

• Flexible options: Available as a 4-, 8-, 16- or 32-fold model for a wide range of requirements.
• Innovative features:
  • Multi-tap function for transferring up to four values ​​(DPTs).
  • Group control via long or extra-long key press.
  • Four integrated logic modules for individual evaluations, e.g. "all windows closed".
  • Pulse and switching counter for integrating external energy measuring devices (e.g. Eltako DSZ).
• Wide range of applications: control of lighting, blinds, scenes and heating applications.
• Galvanic isolation: Each input is galvanically isolated from the KNX bus and from each other – for maximum safety.
• Convenient parameterization: Extensive ETS5 options such as debounce time, blocking objects, thresholds and counting functions.

Technical details

• Entrances:
  • Compatible with potential-free contacts or voltage levels (24V AC/DC, 230V AC).
  • Internal query voltage: 12V (for variants with potential-free contacts).
  • Maximum cable length: up to 100 m.
• Power consumption: Typical consumption < 0.3 W via the KNX bus.
• Environmental conditions:
  • Operating temperature: 0 °C to +45 °C.
  • Protection class: IP 20 – suitable for dry indoor areas.
• Dimensions: DIN rail mounting device (2 modules to 12 modules, depending on the model).
• KNX interface: TP-256, compatible with ETS 5.

Application areas

• Monitoring of door and window contacts in security or energy-saving systems.
• Integration of conventional push buttons and switches into KNX scenes.
• Control of lights, blinds and HVAC components.
• Use as a pulse counter for energy and consumption data recording.

Easy installation and integration

• Mounts directly on the DIN rail (REG).
• Parameterization and commissioning via ETS 5.
• No separate power supply required – power is supplied via the KNX bus.
