The SONOFF MINI-ZBD MINI Dry is a versatile Zigbee-enabled dry contact smart relay switch designed for seamless integration into home automation and low-voltage systems.
- Flexible AC & DC Power Compatibility: Operates on 110–240V AC and 12–48V DC power inputs, making it suitable for standard electrical boxes as well as low-voltage solar or battery-powered installations.
- Dry Contact Output (NO/NC): Features potential-free dry contact relays with normally open (NO) and normally closed (NC) configurations, ideal for operating garage doors, boilers, electric gates, irrigation valves, and alarm circuits without altering existing wiring.
- Low-Voltage DC Load Control: Provides stable switching for up to 8W DC motors and solenoid valves with minimal resistance and fast response times.
- High-Power Expansion: Can be wired with external contactors to switch heavy loads such as air conditioning units, industrial lighting, and high-capacity pumps safely.
- Zigbee Mesh Routing: Connects to standard Zigbee hubs to allow remote management, scheduling, and smart routines via the eWeLink app and platforms like Home Assistant, while also acting as a Zigbee router to extend your mesh network coverage.
