Optoisolators are electrical components which provide electrical insulation between two circuits, for example, between two independently varying voltage sources. The EL816 (M)(A)-V is a type of optoisolator which uses a photovoltaic (PV) output transistor to isolate the two circuits.

The EL816 optoisolator uses a light sensitive device, such as a light emitting diode or phototransistor, to transfer a signal from the input circuit to the output circuit. The light-sensitive device produces an electric current when exposed to light, and this electric current is used to control the output transistor. Once the light-sensitive device detects the light signal, the output transistor is switched on, and current flows from the output circuit to the input circuit. This process creates electrical isolation between the two circuits, and prevents any further signals from reaching the input circuit.

The EL816 optoisolator has a wide range of applications, including controlling the switching of motors, relays, and switches. It can also be used for acoustic modulation and optical communication, as well as for detecting light levels. Additionally, it can be used for voltage level detection, and for protection against electrical transients.

In order to operate the EL816 optoisolator, the light-sensitive device must detect the light signal from the input circuit, and the voltage in the input circuit must be slightly greater than the voltage in the output circuit. If the voltage exceeds the limit of the light-sensitive device, then the device will be unable to detect the light signal. Therefore, it is important to choose an optoisolator that is designed to work with the voltage in the input circuit.

Additionally, the EL816 optoisolator is designed to protect against electrical transients. For example, if there is a sudden surge of high voltage in the input circuit, the output transistor will be switched on, and the voltage will be controlled to prevent any damage to the circuits.

The EL816 optoisolator is also designed to reduce power loss in the circuits. This is achieved by the transistor controlling the current flow between the two circuits, which reduces the amount of energy wasted in the process. This also means that the EL816 optoisolator can operate efficiently even in low voltage environments.

In conclusion, the EL816 (M)(A)-V optoisolator is a reliable and efficient way of providing electrical insulation, and for controlling the switching of motors, relays, and switches. Additionally, it is designed to protect against electrical transients, and to reduce power loss in the circuits.
