Optoisolators, also known as optical couplers, are electronic devices which use light to electrically isolate two circuits in order to protect the input side from interference or voltage problems on the output side. The optoisolator contains an LED and a photodetector. The LED emits light which is then detected by the photodetector. The physical connection between the input and the output is replaced by the LED and the photodetector, creating an electrical barrier between the two circuits.

EL1112-VG is an optoisolator belonging to the "Transistor, Photovoltaic Output" optoisolator category. Designed for use in a wide range of applications such as motion control, industrial controls, medical equipment, and LED lighting control. This optoisolator family is tested per the IEC 60747 standard and is rated according to their maximum output current and output voltage ranges. It is also available in both through-hole and surface mount packages.

The EL1112-VG transformer-coupled optoisolator family uses a photo-detector to drive a MOS field-effect transistor that senses light when the LED is off. The LED is activated when a voltage potential is applied to the n-channel photoFET. When the LED is on, no current flows across the load.

The working principle of the EL1112-VG optoisolator is based on the ability of the LED to convert electrical energy into light energy. When an electrical signal is applied to the LED, it emits light which is then detected by the photodetector. This photodetector then sends an electrical signal to the load which is the same as that of the input signal. In this way, the optoisolator isolates the input and output signals, preventing any interference or voltage issues caused by the output side from affecting the input side.

EL1112-VG has a wide variety of applications due to its versatile nature. It can be used in motion control systems, lighting control systems, electronics, alarms and security systems, data communications systems, and medical equipment. Its isolation feature makes it perfect for applications with potentially hazardous voltages, as it protects the equipment from dangerous currents and voltages. It is also capable of delivering high power levels over long distances without any voltage drop.

In conclusion, the EL1112-VG optoisolator is an ideal choice for a variety of applications due to its ability to isolate input and output signals. This optoisolator family is capable of delivering high power levels over long distances without any voltage drop, making it ideal for applications such as motion control, industrial controls, medical equipment, and LED lighting control. It is also available in both through-hole and surface mount packages making it even more versatile.
