5V coil, 10A/250VAC, optocoupler isolated
| Coil | 5V DC |
|---|---|
| Trigger | Active LOW |
| AC Rating | 250V/10A |
| DC Rating | 30V/10A |
| Isolation | Optocoupler |
This single-channel relay module lets your Arduino or ESP32 switch mains AC loads (up to 250V/10A) or high-voltage DC loads — safely isolated from your microcontroller via optocoupler. It is the simplest way to control a light, fan, pump, or any appliance from code.
When switching mains AC loads (230V), ensure all high-voltage wiring is properly insulated and enclosed. Never work on live circuits. The relay module itself is safe to handle at 5V logic — the optocoupler provides galvanic isolation. For controlling 4 separate appliances, our 4-Channel Relay Module (₹129) is more economical.
