WB-MIR v.3 is a learnable infrared control module with an external IR transceiver and RS-485 interface. IR commands are programmed using the remote control from the household equipment or via the RS-485 interface. The device is used in automation systems for controlling air conditioners, fan coils, heat curtains, TVs, and similar equipment. It is installed inside the enclosure of the controlled device.
The module supports Fast Modbus, enabling instant delivery of input states and button press counter values to Wiren Board controllers.
Key Features
- Compact housing – can be installed inside the device enclosure
- Memory capacity – up to 80 IR commands stored in non-volatile memory
- IR learning – learns commands directly from the equipment's remote control (no need to search command databases)
- 1-Wire input – supports external digital temperature sensor (DS18B20), also usable as "dry contact" input
- Fast Modbus support ⚡ – instant state updates via events
- External IR transceiver included – 3.5 mm connector
- Wiren Board templates – ready configuration templates for seamless integration
- Technical support – available on the Wiren Board portal
Hardware Specifications
Parameter Specification Power supply 9–28 V DC Interface RS-485, Modbus RTU (supports Fast Modbus) IR memory Up to 80 commands (non-volatile) IR transceiver connector 3.5 mm 1-Wire input Compatible with DS18B20 temperature sensor Additional input Dry contact / button press detection and counter Dimensions 34 × 20 × 17 mm Mounting Compact housing, suitable for inside-device installation Fail rate ≤ 0.5% (with 2-year free replacement warranty) Applications
- IR device control – Record signals from IR remote controls of household devices (air conditioners, TVs, thermal curtains, etc.) for automated control
- Hidden installation – Module is installed inside the controlled device, preserving interior aesthetics
- Climate control – Connect external 1-Wire temperature sensor for precise climate control (e.g., air conditioner management)
- Advanced automation – Use wb-rules engine in Wiren Board controllers for more accurate regulation than default device algorithms
Configuration & Setup
With Wiren Board Controller:
- Enable/disable channels and set polling period via web interface
- Control IR command recording mode
- Play back IR commands
- Switch input operation mode
Without Controller:
- Use Wiren Board Web Configurator with WB-USB485 interface converter (or similar)
- Configure via RS-485 by writing values to Modbus registers (open, well-documented register table available online)
Data Reading
- With Wiren Board Controller: Output states are available in the controller's web interface and can be used in automation scenarios or transmitted to upper-level systems. Only channels enabled in polling settings are displayed in the device card.
- Via Modbus RTU: All data is transmitted over RS-485 and can be read by any equipment/software supporting Modbus RTU: third-party controllers, HMI panels, or SCADA systems.
Quality Assurance
All Wiren Board devices are designed and manufactured in-house, undergoing multi-stage quality control:
- Component verification during development
- Automated optical control after SMD mounting
- Visual soldering inspection after leaded component assembly
- Functional testing on automated test station after assembly
- Completeness, labeling, and外观 check before warehouse shipment
