    Tips: How a time delay relay work?

    Timer relay or time delay relay is a kind of relay that realized the time delay control based on the electromagnetic principle or mechanical principle.

    When the coil is energized, the armature and the pallet are attracted by the iron core and move down instantaneously, so that the instantaneous group of contact is switched on or off. But the piston rod and the lever cannot fall along with the armature at the same time. The upper end of the piston rod is connected to the rubber film in the air chamber. When the piston rod starts to move down under the action of releasing the spring, the rubber film is then concave down, and the air in the above chamber becomes thin to make the piston rod fall slowly affected by damping. After a certain period of time, the piston rod moves down to a certain position, and the delay time contact is actuated by the lever, so that the normally closed contact is open and the normally open contact is closed. From the powering-on of the coil to the completion of the delay time contact action, this period is the time limit of the timer relay. The length of the delay time can be changed by adjusting the size of the air inlet of the air chamber. After the coil is de-energized, the relay relies on the recovery spring to restore.

    Which model should we choose for our greenhouse?
    Hello, which model should we choose for a greenhouse: we live in Europe 220V and we would like to switch on a humidifier 220V every 5 minutes for one minute and a fan in a similar cycle. Are both ATO-TIMER-TH100 and ATO-TIMER-TH200 able to do that?

    ATO Responded
    The ATO-TIMER-TH100 model is suitable for the required function, as you can set both delay time (SV) and an output delay time (T).
    The timing function of time relay
    For your TH200 timer relay, how does the timing function begin the countdown?

    The timer relay will keep the original timing state when setting parameters is pressed, and it will take effect immediately after setting the parameters and exiting the setting state.
