Relays are electromechanical devices used to control the flow of electrical power in circuits. They are widely used in various applications to switch high currents, control multiple circuits, provide isolation between different voltage levels, and automate electrical processes.
There are various types of relays designed for different applications. Some common types include:
Solid-State Relays (SSRs),
Time Delay Relays,etc.
When selecting a relay, consider factors such as the required switching capacity, contact configuration, response time, operating voltage, and environmental conditions. It's important to refer to the manufacturer's datasheets and guidelines to ensure the chosen relay meets the specific requirements of your application.
