Setup and operation
Two kinds of relays are existing – delayed switch on and delayed switch off.
Delayed switch on relays engage after a defined period of time, while delayed switch off relays will disengage. The defined period of time can be either fix or variable.
Common uses are start-up procedures of engines or the delayed disengage of a vehicles illumination to ensure a safe and comfort leaving.
A very large number of fixed delay-periods ranging from a few seconds to several hours is already available, different values can be requested.
