The MDT BE-04230.02 is a compact 4-channel KNX binary input module that connects existing 230V AC conventional switches to the KNX bus, enabling smart-home retrofit in small apartments or individual rooms without changing the visible switch fittings. Its 2SU MDRC footprint keeps DIN-rail space consumption to a minimum.
- 4 inputs at 230V AC — integrates up to 4 conventional mains-voltage switches into KNX
- 2SU MDRC DIN-rail format — only 36 mm wide, ideal where space is limited
- Per-channel configuration — short/long press, dimming, blind/shutter control and scene triggering via ETS5/ETS6
- Galvanic isolation — full separation between 230V inputs and the KNX bus
- Front-panel status LEDs — individual channel indicators for fast diagnostics
- KNX certified & CE marked — manufactured in Germany, 3-year warranty

Shipping across Europe
We ship KNX devices and smart home equipment to all EU member states, as well as to the UK, Switzerland and Norway. All orders are dispatched from within the European Union, so there are no extra customs charges or import duties for EU destinations.
- Processing time: in-stock orders are prepared and handed to the courier within 1–2 business days.
- Standard delivery: typically 2–4 business days for Central & Western Europe and 4–7 business days for the rest of the EU.
- Items subject to availability: when a product is not in stock or is supplied on order, the delivery time depends on stock and supplier lead time. The maximum delivery term is 30 days from order confirmation; we will inform you of the estimated date and keep you updated.
- Carriers: tracked courier services (DPD, GLS, DHL) with a tracking number sent by e-mail once your order ships.
- Shipping cost: transport is not included in the product price and is calculated separately, depending on the destination country and distance or the value of the products ordered. The exact amount is shown at checkout.
Payment & Delivery conditions
- Individual products: orders placed in the online shop are processed against 100% advance payment. Products are reserved, ordered from our suppliers and dispatched only after the order value has been paid in full.
- Contracted projects: for a complete project carried out by us (design, supply and installation/commissioning), a 50% advance is required to start the works, with the balance due on completion as set out in the contract.
Delivery terms are estimates that start from the moment your order is confirmed and the advance payment is received. They depend on stock availability and the destination country. In all cases, orders are delivered within a maximum of 30 days unless another term is expressly agreed with you. If an item cannot be supplied within this period, you may choose to wait, replace it or receive a full refund.
Pricing & discounts
The prices listed in the shop are reference prices for individual items and may be subject to change. The final price can be optimised depending on the order value and the scope of your project.
- Volume discounts: the higher the order value, the better the pricing we can offer; tiered discounts are confirmed in your quote.
- Per-project quotation: for a complete KNX project we prepare a dedicated, per-project offer with project-based pricing instead of standard list prices.
- Professional / trade pricing: integrators, installers and resellers receive special conditions — log in to your account to see your prices.
Returns & Warranty
- 14-day returns: in line with EU consumer law, you may return unused products in their original packaging within 14 days.
- Manufacturer warranty: all KNX devices come with the full manufacturer warranty against defects.
- Technical support: our engineers can help with selection, ETS configuration and commissioning across Europe.
