ACPL-W21L-000E Optoisolators – Logic Output Application Field and Working Principle

An optoisolator, also known as an opto-isolator, optical isolator, photocoupler, or optical coupler, is an electronic component that transfers electrical signals between two isolated circuits of different potentials. It consists of a transmitting side, which converts electrical signals into light energy, and a receiving side, which captures the extracted energy and converts it into electrical energy. The receiving side must be specifically designed to operate at suitable levels within a defined environment to allow for a successful transfer of energy.ACPL-W21L-000E optoisolators are a type of optoisolator specifically designed to transfer logic output signals between two isolated circuits. This type of signal is typically encountered in digital circuitry, as it is associated with discrete binary values. Therefore, ACPL-W21L-000E optoisolators are well suited for ensuring secure transfer of digital signals without the risk of malfunction due to stray electromagnetic fields from other electronic equipment.The ACPL-W21L-000E is designed for a wide range of applications, including industrial controllers, programmable logic controllers (PLCs), communications and control systems, alarm systems, security products, and consumer electronics. It is a low cost device with a long working life, and it is also resistant to noise and vibration, making it well suited for applications involving dynamic conditions. The device operates on the principle of light emitting diodes (LEDs), which are activated when the higher voltage input is applied. The LEDs then emit light which is received by an integrated phototransistor and converted into electrical signals. The receiving circuit is then isolated from interference due to its high isolation voltage, which can be up to 5000 Volts. Additionally, the device is equipped with an internal compensation circuit which ensures temperature stability over a wide temperature range.Furthermore, the ACPL-W21L-000E optoisolator comes with a wide variety of features which make it suitable for a variety of applications. The device is available in two power levels; the low and medium power versions, and it is available in a range of voltage levels. Additionally, the device is equipped with a built-in surge protection which minimizes the effects of transient voltage and current spikes. Furthermore, the device is RoHS compliant, eliminating the need for expensive compliance testing. Furthermore, it provides high-density mounting and is capable of operating at temperatures up to 125°C. To sum up, the ACPL-W21L-000E optoisolator is a low cost clever device which provides secure, reliable transfer of electrical signals between isolated circuits. It is a versatile device which is suitable for a range of applications and comes with a range of features which make it suitable for numerous applications.
