Timer Relays
What are Timer Relays?
A timer relay is an automatic component embedded in a time delay function. They work as an integration of an electromechanical production relay and an automated, integrated circuit. These contacts can be made available open or closed; at the same time, they are working for a predetermined duration and can be installed to take a bit more time for the desired outcome, which ranges from milliseconds to hours or might be weeks.
What is a Timer Relays?
When the output contacts open or close, the timer relay differs from an electromechanical relay; for a timer relay, the contacts will open or shut before or after an intentional time period, as opposed to a control relay, where the contacts are opened or closed when a voltage is applied to and removed from the coil. Consider the type of delay needed for your application while selecting the best timer relay.
What are the types of Timer Relays?
The most widely used delay relay is based on timing functions:
- On Delay (Time taking or delay initiates on the application of voltage).
- Off Delay (while a voltage is started, the relay is ready to make use of a trigger)
- Single Shot (One-shot)
- Interval On (Period) and Flasher (On First / Off First)
- Replication Cycle (As soon as a voltage is applied, the relay contacts shift state, and the timer begins).
As soon as building your applications, it is crucial to ensure the distinction between the types of timer interval relays; bear in mind what it would be to initiate the delay and, at the same time, it may start as the application. In addition, to know if the voltage released is working out.
Timer Relays are initiated/introduced by one or the other:
- Current being used or
- The completion or opening of a produced signal.
What are the Applications of Timer Relays?
Time Delay Relays are frequently used in industrial applications, and OEM equipment is crucial for numerous industrial processes, such as those requiring compact panels or sub-panels.
- Illumination circuits
- Electric motor start device
- Responsive equipment
- Protection control
