Optoisolators, commonly referred to as optocouplers, are used to electrically isolate two circuits from each other, providing insulation between components. The H11A2W is among the more common optoisolators available, and is a two-channel device featuring both transistor outputs and photovoltaic outputs. We will now discuss the H11A2W’s application fields and working principle.
Application Fields of H11A2W: The H11A2W is a good choice for applications where switch isolation is needed. This optoisolator is commonly employed in switchgear, motor controls, electronic games, alarm systems, and remote control systems where it reliably helps to maintain and protect the circuits from damage due to inadvertent shocks or system outage.
Working Principle of H11A2W: The two-channel H11A2W optoisolator operates by allowing light to be coupled between two electrical circuits which are electrically isolated from each other. This device utilizes an infrared LED to provide light which is then detected by a photodetector and converted into an electrical signal. By means of this optoisolator, electrical energy can be safely passed from one circuit to another without any physical contact or arcing. The photodetector output provides both transistor and photovoltaic outputs.
The transistor output channel operates consists of an LED emitter, an integrated detector, and a transistor output stage. When light strikes the detector element, it energizes the base of the following transistor. This in turn serves to either switch ON or OFF the transistor output. The photovoltaic output channel consists of an LED emitter, an integrated detector and a photovoltaic output stage. The photovoltaic output stage is capable of producing either a constant current output or a constant voltage output, depending on the application requirements.
In addition to providing electrical isolation, the H11A2W optoisolator also serves to protect the circuits from overvoltage, overcurrent, and electrical noise. It also helps to reduce the amount of power required from the original circuit, as well as preventing electrostatic and inductive interference to the system. Furthermore, the H11A2W is unaffected by most environments due to its hermetic sealed housing.
In conclusion, the H11A2W optoisolator is a reliable and economical device that can be used to securely isolate two circuits from each other while offering a variety of outputs—making this device perfectly suitable for many applications. It is robustly engineered, and the hermetically sealed housing of this optoisolator ensures reliable operation even in harsh environments.
