Special PurposeSpecial purpose isolators are isolators that are designed for a specific application or environment. Isolators, in general, are devices that are used to prevent the transmission of electrical signals or power between two or more circuits or systems. They are commonly used in electronic or electrical systems to prevent interference, damage, or other undesired effects. Special purpose isolators are designed to meet the specific requirements of a particular application or environment, and may have additional features or capabilities that are not found in general-purpose isolators. Examples of special purpose isolators include isolation amplifiers, isolation transformers, and opto-isolators. These products are typically available from electrical or electronic component suppliers, and may be customized to meet the needs of a particular application.
