ACPL-021L-500E Optoisolators - Logic Output Application Field and Working Principle

The ACPL-021L-500E is an optically coupled Logic Output Comparator with an integrated light-emitting diode and an NPN phototransistor on a single chip. It is designed to provide galvanic isolation between two circuits which are communicating through a momentary logic signal. It provides appropriate 8-pins DIP package, .07” lead spacing and 8.0 mA input/output power supply.The application field of the ACPL-021L-500E is mainly for system-level isolation, which includes security, medical, building automation and control system. Its presented 8-pins dual-in-line package design allows this device to be used in most commercial equipment. Its anode-cathode-common scheme further optimizes the efficiency of dynamic performance, extendable both in isolated supply designed and linear optocoupler presented circuit. The ACPL-021L-500E also features with an integrated TTL-compatible output and high-speed response, which provides precise data transmission for anti-jamming purpose applications. As an isolated component, the ACPL-021L-500E opto-coupler consists of an input and an output circuit isolated by a transparent insulating barrier. The input and output circuit are kept completely separated by the barrier. The actual working principle of the ACPL-021L-500E is quite simple. An input is provided to the input device (intensified diode for instance), which causes a TTL voltage compatible light-emitting diode to be illuminated. The illuminated light-emitting diode then illuminates a photosensitive device (NPN phototransistor) in the output circuit which triggers the output switching of the device.The ACPL-021L-500E optocoupler fulfills the isolation requirements to meet the safety and electromagnetic compatibility. It meets all the essential requirement and performance criteria in the European safety regulation (standard EN 60747-5-2 or UL1577). These include insulation coordination, surge, and dielectric strength.The ACPL-021L-500E is the best alternative for the system controller application. It makes the data transmission faster and more reliable and also provides better surge immunity. The adequate performance, robust design and integrated structure of the device offer long term, reliable isolation and durable high-performance communications. It is widely used for various kind of isolation system applications.In conclusion, the ACPL-021L-500E is a popular isolation device that is used in the application field of system-level isolation that includes security, medical, building automation and control system. The actual working principle of the optocoupler is very simple that is an interconnection of two separate circuit through an LED and a phototransistor. The ACPL-021L-500E is more reliable and faster in data transmission which makes it ideal for application purpose. It meets the necessary safety regulation requirements and provides reliable, durable and robust performance.
