    Tips: How to select a timer relay?

    The selection of timer relay mainly focuses on delay mode and parameter. The following aspects should be considered when selecting a time delay relay.

    1. Selection of delay mode
    There are two types of timer relays, power-on delay or power-off delay, which should be selected according to the requirements of the control circuit. The reset time after the action should be longer than the inherent action time, so as to avoid misoperation or even no delay, which is especially important in the case of repeated delay circuits and frequent operations.

    2. Timer relay type selection
    For occasions with low requirements for delay time accuracy, generally use electromagnetic or air damping time delay relays with lower prices; otherwise, for high requirements on time delay accuracy, electronic time relays can be used.

    3. Coil voltage selection
    Select the voltage of the relay's attraction coil including 12VDC / 24VDC / 110VAC / 220VAC, etc., according to the voltage of the control circuit.

    4. Selection of power parameter changes
    Air damping or electric time relays are better than transistors for occasions with large power supply voltage fluctuations, and electric time relays are not suitable for occasions with large power frequency fluctuations, and air damping timer relay is not suitable for large temperature changes.

    Which model of timer relay should we choose?
    Hello, which model of timer relay 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.

    Hello, my dear friend. The model ATO-TIMER-TH100 timer relay is suitable for your required function, as you can set both delay time (SV) and an output delay time (T).
    Timer relay operation
    Can your timer display count down and time delay under operation?
    From: Paul | Date: 06/04/2020

    ATO Responded
    Yes, our timer can display delay time and also can display the count down time during the operation, and also you can set how long the output remains after the delay time reaches!
    Timer relay with normally closed contacts
    For timer relay of model: ATO-TIMER-TH100, I need on normally closed contacts then open when timer goes to zero . Can it fulfill that?

    ATO Responded
    Yes, this time relay has this function >>>> On normally closed contacts then open when timer goes to zero.
    And If you need a group of normally closed contacts, you can choose mode 2 option, but if you need 2 groups of normally closed contacts, you can choose mode 4.
    For my project setup...
    For my project setup, I want to activate one actuator, then the next actuator activates a specific amount of time later. Do you know of a way to hook up my system like this?

    Yes, you can just use our digital timer relay to realize your setup.
