Optocoupler is a component that transfers electrical signals between two state of isolation circuits by using light, and prevent high voltage from affecting the system receiving the signal. I/O relay modules are used in industrial control, building management, and similar applications to connect control equipment to input sources such as limit switches or proximity sensors, as well as output devices such as motors or linear actuators. The six pins on the left side of the relay module connect high voltage, and the pins on the right side connect the component that requires low voltage—the Arduino pins. if you need to round PCB's edges, just use sand paper. Circuit diagram of an electromechanical relay with components are given below: In the above circuit diagram, the 5-volt signal is given to the coil of an electromechanical relay, when the switch is closed, current flows through the coil and energizes the coil. It would take me up to 20 minuites to make one . Reply Features. 3 projects ; 0 followers ; Follow. Circuit Diagram-Home Automation with ESP8266, Relay Module. Introduction.
