4x independent relays, 5V, optocoupler isolated
| Coil | 5V DC |
|---|---|
| Channels | 4 |
| AC Rating | 250V/10A |
| Isolation | Optocoupler |
Four independent relay channels on one board — each capable of switching 250V/10A AC loads, optocoupler isolated, with individual LED indicators. The standard module for home automation controllers, smart switch panels, and multi-zone irrigation systems.
A basic 4-appliance home automation system needs: this relay module (₹129) + ESP32 (₹249) + jumper wires (₹59) = under ₹450 for a Wi-Fi controlled smart switch panel. Add a OLED display for local status indication.
