I have a SPST relay that I do not have the full datasheet for, but I wish to calculate the time it takes to switch on a current for a particular voltage. Is there any easy general way to do this? My first thought would be to time it for a clicking noise, but I don't think that would be accurate for what I need.
My relay is labeled "9V" and rated for 250V AC. I plan to switch on a set of capacitors that will be a few miliFarads at around 350 volts - the current will be around 25A for a very short period of time. Ideally, it would be great if it would be a possible to design a simple circuit that could test this delay accurate to a few jiffies.
EDIT: I'm assuming the relay will have a pretty consistent off-on switching time. If it doesn't, is there any switching circuit with a latency between 10MS and 100MS that can handle the above specifications?
