LOC117 Application Field and Working Principle

LOC117 is an optoisolator which belongs to a class of electrical components called Transistor, Photovoltaic Output (TPO) Optoisolators. It uses photoelectric technology to provide electrical isolation between a monitored circuit and the controlling microprocessor. In addition, the device can be configured as an input device, an output device, or a bidirectional midpoint device.

Optoisolators are popular because they do not require additional external components to function, and they offer superior long-term reliability as compared to other types of electrical isolation devices. In addition, they provide reliability in harsh industrial applications, with great temperature tolerance and durability, and with minimal noise or power dissipation.

The main purpose of LOC117 is to isolate circuits and components with a high-voltage high-current interface. This can be used to control a motor or other high-voltage device, or to provide a data link between two systems, such as a microcontroller and an analog voltage reference. In addition, the device can also be used as an input for protection against high voltage or high current, and as an output in order to provide a signal for controlling a higher voltage or current.

LOC117 features a hermetically sealed housing, a single-stroke reset feature, and a low operating voltage range (2.25 to 6 volts). It also has a high power rating (15 Watts). In addition, it has a high current carrying capacity of up to 300mA, and it can be used as a single-channel or multi-channel optoisolator.

The working principle of LOC117 is based on the transfer of optical energy from one medium to another. In this case, light is emitted from an LED and is detected by a photodetector. The electric field between the LED and photodetector then induces a voltage in the photodetector, which is proportional to the intensity of the emitted light. This will generate an output voltage, which can then be used to drive a circuit or control a device.

In addition to its electrical isolation, the optoisolator also provides bidirectional communications, allowing it to be used as a bidirectional midpoint device. This allows the device to be used for applications such as voltage sensing and control, status monitoring, or data transmission over long distances.

LOC117 optoisolator is a highly versatile, reliable, and efficient component. It is suitable for a variety of applications requiring electrical isolation or bidirectional communication. It is also highly reliable in harsh industrial environments, with excellent temperature tolerance and durability. Furthermore, its minimal power dissipation and noise makes it a great choice for many applications.
