4 Channel Relay Module


It is ideal board to control & switching high current loads like fan, lights, low power heater coils. It not only provides switching but also provides isolation between the power device and your microcontroller. Devices upto 7 Ampere can be switched using this relay. These are 12V relays but can work with any microcontroller, arduino & Raspberry pi as well.

Relay Maximum output: DC 30V/10A, AC 250V/10A.

•4 Channel Relay Module with Opto-coupler. LOW Level Trigger expansion board, which is compatible with Arduino control board.

•Standard interface that can be controlled directly by microcontroller ( 8051, AVR, *PIC, DSP, ARM, ARM, MSP430, TTL logic).

•Relay of high quality low noise relays SPDT. A common terminal, a normally open, one normally closed terminal. •Opto-Coupler isolation, for high voltage safety and prevent ground loop with microcontroller.
