Oh I see, thanks.
By the way, in regular relays (ones with contacts), for the relay to change its state (meaning to change the location of the pole), the coil needs to saturate (become a short)?
I was wondering if its possilbe to determine the coil's value by the switching time thats specified in the spec.
For example, in my relay it is said that the maximal switching time is 15msec, and that the coil resistance is 25ohm (+- 5%), so can is it correct to say that:
L = 15msec * 25ohm = 0.375H ?
