Wi-Fi Wireless Module with one I/O Slot
The WF-IO-4N is a dual-band Wi-Fi universal I/O module designed to easily connect and control external devices over Wi-Fi networks. The WF-IO-4N supports both 2.4 GHz and 5 GHz Wi-Fi bands and adopting Modbus/TCP&UDP and MQTT Protocols, WF-IO-4N can be seamlessly integrated into smart factories, automation control, remote monitoring, and IoT applications. The key feature of WF-IO-4N lies in its modular I/O expansion design. The main unit provides a standardized interface that can be paired with different XV I/O expansion boards, allowing flexible combinations of digital input, digital output, analog input, and relay control. Users can quickly reconfigure or expand I/O specifications according to project needs without replacing the WF-IO-4N module, reducing costs while enhancing system flexibility. In addition, the WF-IO-4N supports wireless firmware updates and features a web-based configuration interface, making installation and maintenance more convenient—no extra software tools required. Whether for single-device control or large-scale deployment, WF-IO-4N delivers a stable, secure, and highly scalable solution. With minimal hardware investment, it empowers users to meet diverse application scenarios, making it the ideal core for smart control and IoT applications.
