Relay Switch Questions

All About Time Delay Relays

If you work with electronics, then you are most likely familiar with the different types of relays out there today, but for those who are not, it can be confusing territory to try to learn about. In the case of time delay relays, the basic concept involved in this type of relay is actually fairly simple. Most relays are activated with very low levels of electricity via a control circuit. The difference with the time delay variety is, as you might have thought, that the circuit is to remain activated for a specific amount of time. A timer circuit is used to control the relay itself. Timers can be set to different intervals and the capacity of a circuit is really only going to be limited by what sort of relay is chosen for use. Often, you will find that this type of relay is used to start and control functions for OEM equipment and when one is building applications. There is typically a shock absorber involved in the mechanism in the actuation of time delay relays that will act as a prevention to the instant activation of the switch when electricity is energizing a given apparatus. This sometimes involves an electromagnetic coil and an armature.

The flow through the circuit ends up being controlled by contacts which will either open or close to control flow of a current through the circuit that the relay is a part of. Since the shock absorber is a part of time delay relays, they are then able to open or close the contacts at the specific time they are set to do so. Voltage needed to do this will be triggered by voltage which is sent to input terminals. Voltage or the opening and closing of a trigger signal via a control switch can be used to activate this kind of relay. These types of relays are exceptionally valuable for the purpose they serve and are widely used in such things such as controlling industrial motors. If you are trying to find a place where you can buy time delay relays, you should know that you can find that easily on the web these days. There are quite a few resources out there that offer to show you how these types of relays are used in a variety of applications, as well, so learning about them is fairly easy to do.

In the end, these are some of the most important types of relays to know about since they do have the ability to give you more control over the flow of current through a circuit. You should know that there are further details, but this gives you the basics of this kind of relay.
