Working Principle

The PC123Y2 works by using an optocoupler, or a photoelectric device, to transfer signals between two circuits of different voltage levels. The device is made up of two parts; an insulated-gate semiconductor (IGBT) and a photodiode. The IGBT component is connected to a power source, while the photodiode is connected to the signal side.The photodiode is activated by a light source, such as an LED, which passes the signal through the IGBT to the other side. This creates a voltage, which is conducted through the IGBT to the other side. The IGBT is what provides the electrical isolation and prevents noise from interfering with the signal.The PV output of the PC123Y2 further increases the device’s functionality. The photovoltaic part takes the power from the IGBT and converts it into a DC voltage, which can be used to power other circuits. This allows for more precise control over the switching and measuring of essential components.
