An industrial timer relay is a type of relay that incorporates a time delay feature. It is designed to control the switching of electrical circuits after a set time period has passed. The time delay can be set for either a specific duration or triggered by certain events. The primary purpose of a timer relay is to activate or deactivate a circuit after a predetermined time, making them invaluable for processes that require a specific time delay between operations.

    Timer relays are often used in conjunction with other control devices, such as switches, sensors, and programmable logic controllers (PLCs), to provide accurate and automated control of systems. They are commonly found in electrical panels, control rooms, and machinery that need to follow sequential operations.
