[Multi-range lantern timer:](https://www.automation24.ir/product-1959/%D8%AA%D8%A7%DB%8C%D9%85%D8%B1-%D9%85% 25D9%88%D9%84%D8%AA%DB%8C-%D8%B1%D9%86%D8%AC-%D9%81%D8%A7%D9%86%D9%88%D8%B3)
It is for timing after connecting the input voltage to the power supply terminals. It has a key to select the time range for seconds and minutes, it also has separate inputs for 24V and 220V supply voltage.
timer:
A timer is a control part that receives an input signal and provides an output signal after a delay time (which is predetermined). Timers are used in various processes in machines and production lines.
A timer is a special type of clock that is used to measure different periods of time. In terms of functionality, timers can be divided into two categories. The first category of timers are those whose time units count starts from zero and goes to a larger number, which is called a stopwatch. The second category is those that count towards zero from a specific point in time.
The function of the timer is such that after connecting the supply voltage, the device can connect and disconnect the output with certain time delays or even immediately. Nowadays, due to the importance of saving and optimizing energy consumption, the use of timers has become doubly important.
If we want to define this device from an industrial point of view, timers or time relays are one of the commanding devices of automatic control circuits, which, like control relays, are responsible for controlling the circuit for a certain period of time, with the difference that control relays control quantities They monitor electrically, but time relays or timers are in charge of timing and creating lead and lag. Another difference between time relays or control relays is that control relays have continuous graphs, but timers have discrete graphs.

Knowing and using timers properly can be very important in industrial processes. If you choose instead of a timer, in addition to implementing the circuits, the assembly speed of the board is increased, the parts and cost are low, and the circuit becomes simple and safe. It was used along with a few auxiliary contacts and a relatively complex circuit. But today, with star-delta timers, a much simpler board with less wiring, safe operation without the need for auxiliary contacts is possible.
Things to know when buying a timer:
Its place of use
supply voltage
Allowable current of its output contact
Work fashions
How to install it
Its dimensions
