Function :

Time relays are designed for use in all areas where time dependent control is required.

But first, we must know what the timer is ( the electric timer) and what is it used in general?

The timer is one of the most important tools used in the field of electrical control, as it automatically connects a circuit after a specified period of time, to operate a load or to deliver electric current to a contactor coil. It is frequently used in control circuits, for the purpose of protecting the components of the drum.

Components of the internal timer

1. Timer feed source:  contains different voltages according to its manufacturer such as 220V/AC or 120VA and so on.
2. Electronic board:  Its function is to control the specified time delay.
3. Rail:  Its function is one of the signals from the electronic board at the end of the time delay period, and accordingly the current reaches the relay coil, then the contact points of the relay are changed.
4. Indicator to control the time delay period.

Timer contact points

1. “Normally Closed” NC:  The points are in their normal state closed and open when the specified delay period ends. It can be used by placing a signal lamp to know the change of contact points from NC to NO.
2. “Normally Open” NO:  The points are in their normal state open and closed when the specified delay period ends.
3. Common point:  It is the common point, as it is directly connected to the electric current.

timer

• In terms of internal installation:

1. Motorized timer.
2. Electronic timer.
3. Air timer.

• In terms of working principle:

1. Timer with “On Delay” system.
2. Timer with “Off Delay” system.
3. Flasher Timer.

Motorized timer

Its principle is based on a small internal motor that drives a group of sub-gears by means of a main gear. This gear has a protruding part that is changed by changing the axis of rotation of the timing, as a result of which the protruding part may approach or move away from the point of contact.

Electronic timer

Designing a circuit that contains electronic parts with a relay of small size. Timing is controlled through an electronic element called variable resistance. This type of timer contains multiple capabilities to perform functions.

Intelligence surpasses vision

Therefore, the timer is used in the time control of electrical appliances, lighting, heating, capacitors, and others.
