EL1019-VG is a type of optoisolator. It consists of an Input and an Output. The Input is a light sensitive device, such as a photo transistor or a photodiode, while the Output is a high-gain, NPN transitor. It has the ability to provide isolation between digital and power circuits.
The EL1019-VG is typically used as an interface device between two circuits that are electrically isolated. It is used to control power circuits containing inductive, capacitive or linear elements. It provides a greater electrical insulation barrier between the circuits than a resistor.
Working Principle
When the Input part of the optoisolator is triggered, it activates the Output part. This output part then drives the powered circuit. The working principle of the EL1019-VG as a photovoltaic output optoisolator is based on the light dependent resistor of the Input part. The light dependent resistor will change its resistance depending on the amount of light and the current applied.
Once the Input light sensitive device is triggered, it will send a signal to the Output, which is in turn called the “drive stage”. This drive stage will amplify the signal from the Input part and then drive the power circuit connected to the EL1019-VG. This allows the input to control the as well as the output voltage and current, providing greater control over the powered circuit.
Application Field
The EL1019-VG can be used in a variety of applications. It is commonly used as an interface device between interface logic control circuits such as microcontrollers, and power circuits. This may include interfacing with HVAC motors, relays, capacitors or inductors. Its high isolation voltage allows it to be used in applications that require higher levels of electrical insulation.
It can also be used in applications where long lead lengths and close spacing are needed such as in drive shaft or motor applications. Additionally, it can be used to interface with switch contacts and circuit breakers. All of these applications can benefit from the optoisolator’s ability to provide isolation from the powered circuit while still providing control of that circuit.
