OPI1280-040

Optoisolators are electronic components used to electrically isolate inputs and outputs from one another. This isolation is necessary to prevent false triggering, ground loop problems, and unwanted feedback in a wide variety of applications. The OPI1280-040 is a type of optoisolator, from the Transistor, Photovoltaic Output family. It can be used for a variety of applications.

Technical Specifications

The OPI1280-040 is a two-channel, 2500VRms, 40A optoisolator with open collector outputs. It has an isolation voltage rating of 1500V peak. It has a working voltage range of 4.5V to 24V, and is rated for 30mA continuous current output, 75mA pulsed current output, and 120mA peak output.

Applications

The OPI1280-040 can be used in a wide variety of applications that require electrical isolation, as it can easily switch digital and analog signals. Some potential applications include:

• Signal isolators
• Audio signal switching
• Motor control circuits
• Medical equipment
• Industrial switches and controls

Working Principle

The main component of the OPI1280-040 is a photovoltaic cell, which produces a current when exposed to light. The cell is connected to an optical amplifier, which amplifies the current produced by the photovoltaic cell. This amplified current is then sent to the optoisolator\'s output, which is an open collector, meaning that it can be connected to an external load. When the output is connected to a load, the load is driven by the current from the optical amplifier.

The OPI1280-040 uses a two-channel design, which allows it to control two separate loads. The two channels work independently of each other, which means they can be used to switch different signals or different outputs. The number of channels can be extended, if needed, by adding additional optoisolators.

Conclusion

The OPI1280-040 is a two-channel optoisolator with open collector output that is used for a variety of applications that require electrical isolation. Its main component is a photovoltaic cell, which produces a current when exposed to light. This current is then amplified and sent to the optoisolator\'s output, which is then connected to a load. The two-channel design makes it possible to control multiple loads at once, and the number of channels can be extended if necessary.
