Product Description

The VL-UB20H-WIFI Module, part of the VL Series Sensor Device family, is a versatile industrial-grade wireless controller designed for robust automation applications. Equipped with 2 digital inputs and 2 relay outputs, the UB20H Wireless Controller can directly interface with up to 4 external modules, supporting seamless integration in scalable systems. It features dual-band Wi-Fi (2.4/5 GHz) and Bluetooth 5.0 for flexible connectivity, compatible with IoT protocols like MQTT and Modbus TCP. Operating within a wide voltage range of 12-24V DC and temperature tolerance of -20°C to +60°C, it excels in harsh environments across manufacturing, smart infrastructure, and energy management sectors. The device incorporates a 5000mAh rechargeable battery for backup power and a 3.5-inch capacitive touchscreen for local configuration. With a 20-meter wireless detection range and IP65-rated housing, it offers reliable performance in dust-prone or humid conditions. Key advantages include real-time data logging, low-latency communication (<50ms), and OTA firmware updates, though users may encounter initial network configuration complexity. This compact controller (120x80x35mm) balances rugged durability with advanced wireless automation capabilities.
