Stair Timer MPN Mahan

Timer or time relay is a key set consisting of a series of open and closed contacts. The mechanism of operation of the timers is that by connecting the power supply to its power supply, it operates on an arrangement that operates after a specified time and its internal contacts change, such that the contacts The timer is used to design command circuits that require timing. In this type of circuits (automatic control), timers have the task of controlling the circuit for a specified period of time. Based on their type of performance they have different modes of work which can be divided into four categories D: - Power On Delay Mode: After the input command is connected, the timer applies the output signal according to the set time.- Power Off Delay mode: After the input command is disconnected, Output is interrupted by a time delay. - Flicker mode or flashing: After the input command is connected, the output is alternately interrupted and connected for a specified period of time. - Interval mode: After the input command is connected, the timer outputs for a specified time. The stair timer, as the name implies, is used for stairs and parking lots. The function of this device is that it automatically switches off the entire staircase lights for a certain period of time, such that when the chassis is pressed (these keys have springs that are pressed again Returns to the first state), all staircase lamps are lit and then switched off again when set before us. The degree of adjustment of the lamp's standby time is embedded in the timer unit, which is usually adjustable from 1 to 20 minutes, as well as the permanent mode of these lamps to remain on permanently if needed. They optimize power consumption and are economically cost effective.
