Centre-tapped photo-couplers have become the standard diode bridge rectifier in many applications. This method enables an inexpensive and reliable power supply for applications like controlling the speed of an electric motor or controlling the brightness of a display. It works by switching active electrical inputs with differential signals using a voltage-rectifier circuit. The HCPL-2611-020E is one such device which specifically belongs to the Optoisolators - Logic Output category.

Optoisolators are used to electrically isolate two parts of a circuit from one another. Each device consists of a dielectric plastic body with an internal reflective mirror and a light-sensitive transistor. The light-sensitive transistor acts as an isolator when directly exposed to light, converting the light into electric signals which can be detected by other components in the circuit. This enables electrical signals to pass between two isolated parts without any direct electrical connection being required. Optoisolators - Logic Output are used to provide an isolation function with the added ability of executing logic operations.

The HCPL-2611-020E provides this electrical isolation and logic function with two separate diodes on each side of the bridge. The two diodes are arranged so that when current flows one way they switch between high and low values, allowing the user to transfer signals at different voltages from one side of the bridge to the other. It also provides isolation between the devices, prevents an electric shock, and is suitable for high-speed inputs up to 100 kHz.

The core of the HCPL-2611-020E is an optocoupler chip, which uses a pair of LEDs and photodiodes to send and receive electrical signals. A pair of LEDs is used to transfer light pulses while the accompanying photodiodes pick up the signals and convert them into electrical signals, which can then be fed into circuitry. The device also contains a static induction transistor (SIT), which stabilizes the voltage output from the photodiodes, ensuring that the signals sent and received are of consistent quality. This ensures that the correct logic state is always maintained.

The HCPL-2611-020E is ideally suited for applications such as motor control, industrial automation, lighting switch control, LED displays, and controlling the speed and direction of electric motors, amongst many other applications. It is a low-cost, reliable and efficient solution which is preferred to more expensive conventional systems. The HCPL-2611-020E is available in a variety of sizes and package types to suit the specific needs of the user.

In summary, the HCPL-2611-020E is an optoisolator that provides the user with an isolation function and the ability to execute logic operations. Its core consists of an optocoupler chip and a static induction transistor which ensure consistent voltage output and reliable logic state operation. The HCPL-2611-020E is highly versatile and is suitable for a range of applications such as motor control, industrial automation, lighting switch control and LED displays. Its price and reliability make it the go-to solution in many applications.
