Hi - I'm looking at using some relays in an upcoming project. Datasheet here.
They're a bit slow for my taste. What I'm wondering is this: could I overdrive the coil of a relay like the one I linked to and make it speed up? For example, could I use the 5V part, drive it for the first 5ms at 12V, then drop the voltage on the coil back to 5V? The idea would be to slam on the relay, but then throttle back to avoid overheating it.
Also - am I right in thinking that there is a resistor in the relay that is acting as a current limiter? Can you buy relays without that and then use your own current limiting system?
