Relay Module (1 Channel - 5V) 7490 TIP142 NPN Power Darlington TransistorIntroduction : It is a 1 channel relay board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other equipment with large current. used where it is necessary to control a circuit by a low power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.
