Description
Impulse relays compact are used to switch on and off consumer for defined time period. Please specify the required pulse length in your order .
Application Examples
Preheat controller
windshield wiper
Function Diagram S1 and S2: To terminal 30, the supply voltage is applied. If a control voltage is applied to terminal 15, the relay switches-on for the given time period and switches-off afterwards. The duration of the input impulse has no impact on output impulse duration.
Diagram S3: Supply voltage is applied to terminal 87z. If a control voltage is applied to terminal 15, the relay switches-on for the given time period and switches-off afterwards. Is control voltage taken away before, the relay switches-off directly. The duration of the input impulse has no impact on output impulse duration.
Diagram S2 and S3: The contacts are seperated from the trigger, therefore they can be used in combinations. Regarding version S2 and S3 the relay contact is completely potential-free thus it is able to switch alternating voltage.
For different housing please see in the chapter housing and baseplates.
