I am not entirely sure what the device you are describing is. Is this some kind relay with two stable unpowered states, like a relay with latching capability? Sasha, Yes, exactly. That's what it is... Sasha Jevtic said:
It seems though that the question you are asking has less to do with the nature of the switching device itself than it does with detecting the presence or absence of a large AC voltage. Again correct, Sasha, but I want to avoid that I'm not giving enough information... ;-) That all was a little bit the context in which it has to be used, that's all... Sasha Jevtic said:
Although you could filter that out in hardware or software, you might be happier working with an integrated AC line monitor device like the Fairchild MID400. Use of this device is straightforward, and provides just about all the functionality required for detecting the general presence of an AC input on a macroscopic time scale; depending on your system, you will probably need little more than a current limiting input resistor.
--Sasha Jevtic That's just great! Will have a look to this device right away! Thanks for this input! Best rgds, --Geert |
