5V Relay Module — 8 Channel
—An eight-channel 5V relay module switches eight circuits from one board, used where a controller has to manage a whole irrigation or lighting system.
Specifications
- Eight 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
- Needs a dedicated 5V 1A+ supply for the relay side
What you can build with the 5V Relay Module — 8 Channel
- Eight-zone irrigation controllers
- Whole-house low-voltage lighting
- Greenhouse and glasshouse systems
- Equipment sequencing in a workshop
Compatibility
Works with Arduino Mega, ESP32 and Raspberry Pi — eight pins is a lot on a small board, and a PCF8574 I/O expander can drive it over I2C instead. Power the relay side separately. Low-voltage circuits only.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
