Hi,
I have little or no experience in designing circuits and need some
help.... Please!
I have a 24V line out to a contact block. The 24V is connected across
1&4 and a 2-position valve is connected across 2&3. When the 24V is
applied, the valve switches to position 2, and when it is switched
off, it switches back to pos 2.
I want to connect another piece of kit with a contact closure across
this, so that when the valve switches direction, it closes the
contact.
ie when it switches to 2, the contact is closed, and when it switches
back to 1 the contact is closed again. Effectively sending a pulse at
each valve switch.
Obviously, simply connecting these in parallel will not work - the
contact will only close once.
I have a few ideas (logic gates, capacitors) etc, but no idea how to
implement them!!
Help would be greatly appreciated! Please either reply here or email
comments to the hotmail address above or
simondeane@"!DONTSPAM!"bigfoot.com.
Many thanks,
Si
