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.
