3-channel
Modbus-DALI Gateway

A 3-channel RS-485 gateway for controlling DALI-2 (IEC 62386) devices with Wiren Board controllers. It lets you integrate modern lighting systems (LED drivers, sensors, switches, ballasts) into industrial automation and smart home projects.

Key features

Advantages

  • three independent DALI buses;
  • protection against short circuit, overheating, and overvoltage;
  • support for DALI-2 devices (LED drivers, ballasts, sensors, buttons);
  • 7 discrete inputs for connecting buttons;
  • recognition of 4 press types (short, long, double, short+long);
  • isolated RS-485 interface;
  • operating temperature range: -40 to +60 °C;
  • compact DIN-rail enclosure (3 modules). Supports Fast Modbus ⚡, which delivers input states and press counter values to the Wiren Board controller instantly.

Hardware

Technical specifications:

  • 3 outputs for connecting DALI buses (DA1: 200 mA, DA2: 100 mA, DA3: 100 mA);
  • 7 discrete inputs (dry contact);
  • output voltage 19 V;
  • group galvanic isolation of inputs;
  • protection of each bus against short circuit, overheating, and overvoltage;
  • supply voltage:
    • 9…28 V DC,
    • 230 V AC;
  • interface: RS-485, Modbus RTU.

Fast Modbus support

In addition to standard Modbus RTU, all Wiren Board devices support the Fast Modbus ⚡ extension, which adds:

  • instant polling of input states and counters via events;
  • fast discovery of devices connected to the bus;
  • resolution of address collisions on the bus.

Enabling these extra capabilities is seamless for the user — if a device supports the extension, the controller's driver communicates with it over Fast Modbus; if the device knows nothing about the extension, it works over standard Modbus RTU.

Configuration

On a Wiren Board controller, you can use the web interface to:

  • enable the internal power supply for each DALI bus;
  • set button press behavior and input trigger reactions;
  • control DALI devices: assign addresses, groups, scenes;
  • configure the brightness control curve (linear / DALI standard);
  • run device identification (light flashing);
  • view bus status and diagnostics.

Quality control at each stage of production

We develop and manufacture all Wiren Board devices ourselves. Also everyone devices undergo multi-stage quality control:

  • During development - checking the components used for compliance with the declared ones characteristics and testing of the prototype device at extreme operating conditions.
  • After installation of SMD components - automated optical control.
  • After soldering the lead components - visual inspection of soldering.
  • After assembling the device, functional testing on an automated stand.
  • When shipped to the warehouse - control of completeness, stickers, appearance.

Thanks to this approach, the failure rate is no more than 0.5% of all released devices.

If the device fails within two years from the date of purchase, we will replace it for free without need to be sent to a service center.
