Description
YO Relay Switch is a LoRaWAN device designed for versatile remote control applications. Equipped with two control channels, this device enables seamless monitoring and control of various systems in building management, agriculture, and industry. Each channel is equipped with a 16 A latching relay rated for switching loads of up to 16 A at 250 VAC, while many comparable relay nodes are limited to 10 A. Thanks to the latching design, the relays keep their state even after a power loss. This actuator can transmit the status of its input while managing its output, providing flexible control options. Operating in LoRa Class C, it continuously listens for commands, ensuring prompt response times and reliable communication. It is well-suited for managing lighting, heating, cooling, HVAC systems, security systems, irrigation, and industrial machinery. Integration via Bluetooth Low Energy (BLE) ensures convenient setup. Users can easily manage and monitor the device through a free mobile application, providing user-friendly operation and secure data transmission.
Key features
- High-Capacity 16 A Relays: Each channel switches resistive loads of up to 16 A at 250 VAC or 16 A at 24 VDC, with a 10 kV impulse withstand voltage between the coil and the contacts. The relays are TV-8 rated, making them suitable for loads with high inrush currents, such as lighting.
- Latching Relays: The relays hold their state without powering the coil, which lowers energy consumption. After a power loss, the outputs remain in the same state as before.
- Dual control channels for versatile application possibilities
- LoRaWAN Class C device for continuous listening and reliable communication
- Remote monitoring of input status and control of outputs
- Easily scalable for managing multiple units within a single network
- Suitable for lighting, heating, cooling, HVAC, security systems, irrigation, and industrial machinery
- Cost-effective solution with competitive pricing and low operational costs
- Supported LoRaWAN network type: private or public and connection over ABP or OTAA
- ISM band selectable for regional needs (EU868, US915, AU915, and AS923)
- Configuration via Bluetooth Low Energy 5.0
- Firmware update over BLE
- Easy management of the device via the free Yosensi Mobile Application
- Yosensi Configuration Web Tool for convenient firmware updates and device configuration
- Wide network coverage and very low energy consumption
- High-quality product made in EU
