Description
EL817(S1)(C)(TU) is a transistor output optocoupler. Also known as optocoupler transistors. An electronic device used to isolate signals between two circuits while allowing information to be transmitted. They consist of an LED (Light Emitting Diode) and a phototransistor. Connection via transparent or translucent insulating material.
The device works by converting an electrical signal from a circuit into light. It is then picked up by a phototransistor in another circuit. A phototransistor then converts the light back into an electrical signal. Can be used to drive output circuits.
In DC input applications, optocouplers are often used to isolate the input signal from the output circuit. For example, in motor control systems, optocouplers can be used to isolate control signals from high-voltage power circuits.
The main advantage of using optocouplers is that they provide electrical isolation between the input and output circuits. This helps prevent noise, interference, and voltage spikes from affecting the output signal. Additionally, optocouplers can provide galvanic isolation. This means they can isolate circuits with different ground potentials.
