I'm dealing now with the different types of time responses of electromechanical relays: instantaneous, definite time lag, inverse time lag, and inverse definite minimum time lag.
My question is: What's the difference between the last two time response? What are the advantages/disadvantages ? Is it "bad" to have a definite minimum in an inverse time lag delay?
The way I read it, the definite time lag gives a constant delay from the time some minimum current is applied to the time the relay is activated. That way you can, for instance, sequence events triggered by the same activation. The inverse definite minimum will do that too, but additionally gives you the option to extend that time by applying a current lower than the minimum for the guaranteed delay. That guarantees it won't happen too quickly, but at the same time allows additional control based on immediate circumstances.
