Timer SEMT20 SEVEN

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. Disconnect and disconnect after this time.
