Time Delay Relays

A time delay relay is a type of electrical relay that is designed to open or close a circuit after a specific amount of time has elapsed. Time delay relays are commonly used in a wide range of applications, including timers, sequencers, and alarms. They are available in a variety of different styles and configurations, and they can be used to control a wide range of loads, including motors, solenoids, and lights. Time delay relays are typically controlled by an external trigger signal, such as a switch closure or a voltage signal. When the trigger signal is received, the time delay relay starts a timing cycle, and the contacts of the relay open or close after the specified time has elapsed. Time delay relays are available with a variety of different timing ranges, and they can be set to delay for as little as a few milliseconds or as long as several hours. They are often used in applications where a delayed response is desired, such as in automation, control, and safety systems.
