5V Relay Module — 4 Channel
—A four-channel 5V relay module switches four independent circuits from four pins, the common size for irrigation zones and multi-room control.
Specifications
- Four relays, contacts typically 10A at 250VAC / 30VDC
- Opto-isolated inputs
- 5V coil supply, 3.3V-compatible triggers
- Screw terminals per channel
- Status LED per channel
- Draws roughly 70mA per energised relay
What you can build with the 5V Relay Module — 4 Channel
- Four-zone garden irrigation
- Multi-room lighting or heating control
- Aquarium equipment scheduling
- Workshop equipment switching
Compatibility
Works with Arduino, ESP32, ESP8266, Pico and Raspberry Pi. Four energised relays draw more than a board's regulator can supply — power the relay side from its own 5V source. Low-voltage circuits only.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
