Timer Relays

"

Timer Relays are a type of Control Relay with a time delay built in.

Timer Relay or Electromechanical Relay?

The difference between the timer relay and electromechanical relay is that when the output contacts open or close. On a conventional Control Relay, the contacts are opened or closed when a voltage is applied and removed from the coil - for timer relays, however, the contacts will open or close before or after an intentional time period. When choosing the right Timer Relay it is important to consider the right kind of delay required for your application.

What are the types of Timer Relays that I can choose from?

The most common timing function of Time Delay Relay are:

  • On Delay (Time delay starts on the application of voltage)
  • Off Delay (When a voltage is applied the relay is ready to accept a trigger)
  • Single Shot (One-shot)
  • Interval On (Interval) and Flasher (On First / Off First)
  • Repeat Cycle (When a voltage is applied the relay contacts change state and the timer starts)

When designing your application it is important to understand the difference between the particular types of the timer relays. That means to consider what should initiate the delay and whether the timing should start at the same time as the application as well as when the voltage is released.

Timer Relays are triggered/initiated by either:

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

Trigger signals are either:

  • Control Switch ( Dry Contact) such as a limit switch, float switch or push button or
  • Voltage ( Power Trigger)

Where can I use Timer Relay?

Time Delay Relays are typically used in industrial applications and OEM equipment play an important role for many industrial processes such as small panel or sub-panels requirements.

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