Why You Must Experience Timer Relay At Least Once In Your Lifetime

A timer relay is a control relay that features a built-in time delay function. They function as a combination of an electromechanical output relay and a control circuit, in which contacts can be easily opened or closed before or after a predetermined interval. Timer Relays are standard of two types: normally open and normally closed, which delay time functions from milliseconds to hours and even reaching days.

Types of Relays

• The most common timing function of delay relay is stated as:
• On Delay in this, the Time delay starts when voltage is applied
• Off Delay is when a voltage is applied, and the relay is ready to accept a trigger
• Single Shot
• Interval On (Interval) and Flasher, which could be On First / Off First
• A repeat Cycle is when a voltage is applied, the relay contacts change state, and the timer will start.

When designing your applications, it is essential to understand the difference between the various types of timer delay relays. This is done with the concern of what should initiate the delay or if it should begin simultaneously with its application and when the voltage is released.

Timer Delays are Triggered By:

• The voltage being applied or
• The opening or closing of a trigger signal

Timer Relay Vs Electromechanical Relay

The main difference between the timer and electromechanical relays is when the contacts will open or close. For example, in conventional control relays, the contacts will open or close when a specific voltage is applied and eliminated from the coil. Whereas, for timer relays, the contacts will open or close before or after a set period. When buying these relays, it is crucial to determine the type of relays that best suits your applications.

Applications of Timer Relays

Timer relays are used in various applications, and the OEM equipment plays a crucial role in many industrial processes such as small panel or sub-panel requirements.

• Lighting circuits
• Motor start control
• Sensitive equipment
• Safety control
• Conveyor belt sequence relay.
