Optoisolators, otherwise known as optocouplers, are electronic components used to isolate signals electrically and optically. The VOM618A-5X001T is an optoisolator that belongs to the Transistor, Photovoltaic Output category. This type of optoisolator isolates voltages or currents between two circuits by using a light emitting diode (LED) integrated on one side, and a phototransistor on the other side.

Application Field

The VOM618A-5X001T optoisolator is ideal for use in a variety of industrial applications that require electrical isolation. It is commonly used to isolate signals and control the turn-on and turn-off of power circuits, as well as provide insulation for electric signals in areas prone to interference from other signals. Examples of such applications are vending machines, automated factories, electric circuits, and industrial automation systems.

In addition to industrial applications, the VOM618A-5X001T optoisolator can be used for a variety of other applications. It can be used in overvoltage protection systems, signal and power monitoring systems, logic control systems, and power control systems.

Working Principle

The VOM618A-5X001T optoisolator contains two separate parts: an LED and a phototransistor. The LED emits light that is then detected by the phototransistor. When the LED is turned on, the phototransistor is activated and it, in turn, controls the circuit on the other side. The electrical isolation provided by the LED and phototransistor prevents any electrical interference between the two circuits.

In a simple example, the LED is used to turn on a light bulb on the other side of the optoisolator. When the LED is turned on, the phototransistor detects the light and allows the electricity to flow through the circuit, causing the light bulb to turn on. When the LED is turned off, the phototransistor stops conducting electricity, and the light bulb is turned off.

The VOM618A-5X001T optoisolator also includes a diode that helps protect the LED from voltage spikes caused by inductive loads. This helps to prevent the LED from burning out and allows for a more reliable operation.

Conclusion

The VOM618A-5X001T optoisolator is an ideal choice for applications that require electrical isolation. It has a wide range of uses in industrial and non-industrial applications, and its integrated diode helps to keep the LED from burning out due to voltage spikes. As this type of optoisolator belongs to the Transistor, Photovoltaic Output category, it is important to pay close attention to the specifications of the device and the requirement of the application.
