Shelly SSR Add-on (Shelly Pill)
- Silent Solid-State Switching: Because it uses advanced solid-state technology instead of traditional mechanical relay contacts, it operates completely noiselessly. This eliminates the annoying clicking sounds, making it perfect for quiet home or office environments.
- Dual-Channel DC Control: The module provides two independent potential-free channels (LOAD1 and LOAD2). This allows a single, highly compact unit to manage two completely separate automated functions simultaneously (e.g., controlling a fan on one channel and a locking mechanism on the other).
- Galvanic Isolation for High Safety: Both outputs are completely galvanically isolated. This electrical isolation protects the main microcontroller system and connected hardware from potential low-voltage power disruptions or back-EMF spikes.
- Configurable Digital Input/Output: Features one flexible 3.3 V logic-level port (IO3). This digital terminal can be configured as either an input or an output based on your specific automation needs.
- Zero Mechanical Wear: With no moving mechanical components, the module suffers significantly less wear and tear over time compared to traditional relays, dramatically improving the device's overall lifespan and physical reliability.
- Ultra-Low Power Consumption: Operates highly efficiently, drawing less than 0.6 W of power during operation.
- Extremely Compact Footprint: Measuring just 36 × 31 × 11.5 mm and weighing only 12 g, it easily fits into tight spaces, small equipment cabinets, or custom low-voltage DIY project boxes.
