Timer relays with fixed timing values are common, for use in applications where timing set points are not expected or intended to be adjustable.Įagle Signal offers a wide variety of reliable timer relays for all your applications, from simple on-off control to advanced control options.Timing values may be set by an analog dial and knob, digitally with a keypad, with dipswitches, jumpers, thumbwheels, or other simple means.Ease of use is another benefit of timer relays, as most models are designed to plug into a socket or other standard connection system, thus allowing for prewiring of the connections and insertion of the timer relay when ready.Looking at time on delay and time off delay using transistors, capacitors and diodes as well. Compatible with a wide range of applications including machines, buildings. Time Delay Relays, in this video we learn the basics of how time delay relays work. Due to their inherent compact size, timer relays can be implemented into a very broad range of applications without using up large amounts of often scarce panel space. Wide range of time delay for adjustment: from 0.01 s to 999 hrs.Timing functions for timer relays include but are not limited to: on-delay, off-delay, and interval/one-shot modes.Lighting systems can be automated to stay on for certain periods of time. Even modern lighting benefits from smart controls. A programmable relay offers an easy-to-use, low-cost option to add automated control. Timer relay contacts are generally rated for 5 to 10amp resistive loads, and can often be supplied with solid state output contacts for lower level switching applications. Only the simplest powered electrical systems and equipment require just an on-off switch.They are small in size and offer unequalled performance in their role. Aside from the ability to allow a relatively small electrical signal to switch a relatively large electric signal, relays also offer electrical isolation.Timer relays also provide timing functions in the circuit. Timer relays are very versatile in that they provide the basic switching or controlling function as mentioned above.Hopefully, this brief explanation will help understand the 8 most important factors to consider when selecting a timer relay. The task of selecting a relay can often prove to be difficult and confusing. It is virtually impossible to design a control circuit in a system without using timer relays. Timer relays add an extra dimension of applicability due to the capability of introducing the element of time into the control circuit. Timer Relays provide a high degree of isolation between power wiring and control wiring as well. They use one level of voltage or current to control a different level of voltage or current.
