Optoisolators are electronic components which use optically isolated interfaces to transfer signals between two circuits or devices. One of the most commonly used types of optoisolator is the H11L2S, which is a logic output type optoisolator.The H11L2S is primarily used in applications where the objective is to transfer current or voltage signals from a digital circuit, such as a computer, to a secondary circuit, such as a relay. This kind of optoisolator can be used in a variety of different applications, such as motor control, telecommunications, process automation, and medical equipment.The main function of the H11L2S is to allow secure, uninterrupted communication between a digital circuit and a secondary circuit. By using optically isolated interfaces, the H11L2S can transmit a high-level signal (at a voltage up to 15V) to an external circuit without interference from other sources or accidental electrical shorts. This helps prevent interference from noisy circuits or short circuits that can cause errors in communication or unintended hardware malfunctions.The H11L2S also provides a higher degree of noise immunity than traditional electrical isolation techniques. This is because the high-level signal is transmitted using an infrared light source, which is not subject to electromagnetic interference. This makes the H11L2S ideal for use in applications which require greater noise immunity and signal integrity than what is possible with electrical isolation techniques.The H11L2S is also easy to use and has a fast response time. To operate the H11L2S, a digital input signal is applied to the optoisolator’s input and the output signal is then transmitted via an infrared light source to the external circuit. The output signal is correctly polarized, so it can be received by the external circuit without any additional processing or development. The response time is also very fast, with a rise time of 500ns.The H11L2S is usually constructed using a single integrated circuit package that is comprised of both an input side and an output side. The input side is comprised of a LED (Light Emitting Diode) which is optically coupled to a controlled rectifier. This arrangement works on the principle of photoconduction, where the input is a square wave and the output is a pulse width modulated (PWM) waveform. On the output side, the optoisolator contains a photo detector and an NPN type switch, which are both connected in series to an external load. When the LED is activated, the photo detector will detect a high-level signal and switch the NPN junction within the optoisolator, thus allowing for the transmission of the signal to the external load.Overall, the H11L2S is a highly useful type of optoisolator which offers a reliable solution to reduce noise interference and improve the signal integrity of digital circuits. It is well-suited for applications such as motor control, telecommunications, process automation, and medical equipment, as it has a fast response time and offers a higher degree of noise immunity than other types of optoisolators.
