下面為大家介紹的是德國DOLD多德時間繼電器,純英文多德DOLD時間繼電器介紹,德國DOLD時間繼電器英文樣本,DOLD時間繼電器規格技術參數如下:
Timing relays are available as electropneumatic, electromechanical and electronic design. Electropneumatic and electromechanical timing relays work with conventional relay contacts. Electronic timing relays work with conventional relay contacts or with solid-state relays.
Functions
Delay on operate: Initiation is by applying the operating voltage. Once the set delay time has lapsed the relay switches to its operated condition.
Release delay: When the operating voltage is applied the relay immediay switches to its operated condition. When the operating voltage is interrupted, the release delay time starts. Once the set delay time has lapsed the relay switches to its normal position.
There is a differentiation between devices without and such with auxiliary voltage.
Devices without auxiliary voltage can only control short times (up to 5 minutes), devices with auxiliary voltage are also suited for longer times because their delay function is initiated by triggering the control input. These products are also suited for applications with very short operating times.
Flasher timers: When the operating voltage is applied the relay switches to its operated condition (on the lead edge of the pulse). Once the pulse time has lapsed the relay switches to its normal position. After the end of the dead time it returns to its operated condition and so on (pulse time = dead time).
德國DOLD時間繼電器英文樣本 Cyclic timers: Same functions as the flasher timer, but pulse time and dead time are different and therefore they can be separay adjusted.
Fleeting action: A fleeting action NO relay switches to its operated condition without delay when the operating voltage is applied. Once the set fleeting time has lapsed the relay switches to its normal position. A fleeting action NC relay has voltage applied to the control input via the control contact. When the control contact is opened the relay immediay switches to its operated condition. Once the set fleeting time has lapsed the relay switches to its normal position.
Pulse shapers: Convert the input pulse to an output pulse with a defined length (set time).
Multifunction relays: These devices can be used for each one of the above functions. Needed functions can be adjusted on the device.
Star delta timers: The star contact is closed when the operating voltage is applied. Once the set fleeting time has lapsed the star contact opens and after a short dead time (contact transit time 35 to 100 ms) the delta contact closes.
