On Delay Timer Relays

An On Delay Timer Relay is an electrical device used to introduce a time delay before energizing or de-energizing a circuit. It is commonly used in various industrial and automation applications where timing control is required.

How does an On Delay Timer Relay Work?

The purpose of an On Delay Timer Relay is to provide a delay between the input signal and the output action. When the input signal is received or a circuit is energized, the timer relay starts its timing cycle. After the pre-set time period elapses, the relay contacts change state, either closing or opening the circuit, depending on the configuration.

The time delay provided by the relay can be adjusted based on the specific requirements of the application. The delay can range from a fraction of a second to several hours, depending on the timer relays design and capabilities. Some timer relays allow for precise adjustment of the delay time, while others have fixed time increments.

Applications of On Delay Timer Relays

On Delay Timer Relays are used in various applications, such as motor control, lighting control, sequential control circuits, HVAC systems, and process automation. They can be employed to prevent immediate equipment start-up or to introduce a delay between different stages of a process.
