5V Relay Module — 1 Channel
—A single-channel 5V relay module lets a microcontroller switch one separate circuit, with an opto-isolator keeping the two sides electrically apart.
Specifications
- One relay, contacts typically rated 10A at 250VAC / 30VDC
- Opto-isolated input
- 5V coil supply, 3.3V-compatible trigger on most boards
- Normally-open and normally-closed screw terminals
- Status LED
What you can build with the 5V Relay Module — 1 Channel
- Switching a single 12V pump or light
- Garage door and gate triggers
- One-off appliance automation
- Home Assistant single switch node
Compatibility
Works with Arduino, ESP32, ESP8266, Pico and Raspberry Pi. In New Zealand, permanent mains wiring is registered-electrician work — use these on low-voltage circuits.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
