I believe that we are all familiar with the relay. The timer relay is an electronic control device. It has a control system (also known as the input circuit) and a controlled system (also known as the output circuit). It is usually used in automatic control circuits. It is actually An "automatic switch" that uses a smaller current to control a larger current.
Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
Relays are commonly used in low-voltage control circuits. There are many kinds of relays that we know about low-voltage, such as intermediate relays, time delay relay, and time relays.
Let's talk about the time relay. The time relay is a very important component in the electrical control system. In many control systems, it is necessary to use the time relay to realize the delay control. The time relay is an automatic control device that uses the principle of electromagnetic or mechanical action to delay the closing or breaking of contacts. Its characteristic is that there is a delay between the time when the attracting coil gets the signal and the action of the contact. Time relays are generally used for motor starting process control that is a function of time.
The main function of the digital timer relay is as an executive device in simple program control. When it receives the start signal, it starts timing. After the timing is over, its working contacts open or close to promote subsequent circuit work. Generally speaking, the delay performance of the timer relay switch can be adjusted within the design range, so that it is convenient to adjust its delay time.
A single time relay may not be able to start delayed closing, close for a period of time, and then open, first achieve delayed closing and then delayed disconnection, but generally speaking, by configuring a certain number of time relays and intermediate relays .It's all possible.
When choosing a 24v timer relay , attention should be paid to the current type and voltage level of its coil (or power supply), and the delay mode, contact form, delay accuracy and installation method should be selected according to the control requirements.

It is a very important component in the electrical control system of the time delay relay 24v . It is generally divided into two types: time on relay and off delay time relay. From the principle of action, there are electronic, mechanical and so on. The electronic type uses the principle of capacitor charge and discharge and cooperates with electronic components to realize the delay action. There are many mechanical styles, including the airbag type using airbags and springs, the watch escapement type, and the use of small shaded pole synchronous motors to drive the cams. Now there will be more new-style time relays appearing.
The purpose of the programmable timer relay is to meet the process requirements and perform delay actions.
