Manufacturer and distributor specifications

  • 12 output channels rated 10 A each (channels 1–12) and 9 channels rated 16 A each (channels 13–21).
  • Two additional dry-contact inputs; the output channels are configurable for switching, shutter and other supported functions through KNX ETS.
  • KNX bus operating voltage approximately 30 V DC; 35 mm DIN-rail module measuring approximately 216 × 90 × 64 mm, IP20.
  • Multiple functions share the available channels. Do not assume that all stated maximum output configurations can be assigned simultaneously.

Required engineering checks

Commissioning by a KNX-qualified integrator is required. Verify channel loading, protection, control topology, bus power, CE documentation and intended use. The distributor photo is model-matched to MXR21Y-KS.13; the current supplier price and stock still require confirmation. This product remains unavailable for direct sale.
