How can I choose the best timer relay?
timers relay is a device used to turn on or off the perimeter after a certain time, and while many models seem similar, some factors will help you determine which relays are best for your needs. If you have a basic circuit, you may need only one timing range; If the circuit is more complex, several delay settings may be required. The timers will have a minimum and maximum time limit, and they should be at a satisfactory operating level. Timers in this relay can come in digital or analog styles. Functions for delay and out of delay help run the relay when you are not around. The basic relay will only have one timing range, which means that you can set a relay open every five seconds. Complex circuits may require several ranges; If there are two ranges, you can set the circuit to open three seconds in alternating samples for three seconds. You should check the circuit to find out how many ranges it will require for spraythe extent of use.
Most timer relay devices have a minimum and maximum time limit and you cannot set a lower or higher time than these limits. The common range is about 0.01 to 0.05 seconds for a minimum and about 50 to 100 hours for the maximum. If your circuit needs a shorter or longer period, check the relay specifications to make sure it fits your requirements.
normally has a timer relay that allows you to set relays, and this face comes as digital or analog. Although it is usually a priority, each relay face has its own purpose. The digital face makes it easier to set the exact times, especially for very short or long time limits, while the analog face is usually cheaper and can be easier to set for medium time limits.
Most timerships relay have a delay function and out of delay to automate relay use. For exampleD on-Delay allows you to determine when the device turns on; If you leave the relay in the room but must start working in a few hours, the delay will allow him to work without returning to the relay. Even if a relay can be used without these functions, you can forget to turn on or off the relay, which may have poor effects for any circuit controls. This means that it is usually desirable to obtain a relay with one or both of these functions.
