1 Channel Optocoupler Relay Board
Relay board module is used for controlling higher current loads from your microcontroller development board, PC parallel port, or Arduino Uno. This board has one (1) on-board relay which can switch up to 7Amps. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor BC547 hence your input device, such as Arduino, is protected from the relay circuit. There is a freewheeling diode that will further protect your microcontroller from relay kickback. Single-channel 12 volt relay connections are
- Connect VCC to the 12-volt power supply
- The control signal is used to control the relay. If the signal will be HIGH (5V) the relay will be switched to NO(Normally Open) and if the signal is LOW (0V) the relay will be switched to Normally Connected (NC)
- If the control signal is high the led will glow and Vice- versa.
This is a 12V 1-Channel Relay interface board that can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, 8051, and so on.
