Hi every one, I'm hoping someone can confirm a basic timed relay install for me.
So I've recently taken up a position as the engineer and maintenance tech of a brewery here in Ireland, my skills are mostly mechanical and would defiantly say electrical design work would be my Achilles heal.
I've been asked to look at a kegging machine in the brewery, this has a 5/2 solenoid valve set to drive the pneumatic pars of the machine. When the kegging operation is finished the valve close but it takes about 5 seconds for the pneumatic ram to return to it ready position. it uses the exhaust port to do this. The problem is for the valve to work it needs to have a exhaust when not in operation to return to ready position. Closing off this exhaust courses the main ram to drop. We waste alot of air during a working day because of this constant exhaust after the machine is reset. This is what I need help with.
What I want to do is used the signal from the 5/2 solenoid to operate a time delay relay that it self opens a solenoid valve to let the pneumatic pressure to it. Then after the 5/2 signal moves to the off position I want to have a 5 second delay that closes the pneumatic pressure shut off solenoid valve.
Please correct me if I'm wrong but from what i understand a timed relay requires a permanent live and earth to it the operate the relay and timer then the out power to operate something (Solenoid in my case) and the an on off signal input(Use the connections to the 5/2 solenoid valve set?)
The problem is I'm not sure of what parts I'm looking at will suit or if what I'm thinking about will even work. its all running on 24v and was looking for the cleanest option as i haven't much room to install loads stuff. I was hoping something like this might work as a complete unit - http://www.ebay.co.uk/itm/MULTIFUNC...t=LH_DefaultDomain_3&var=&hash=item2c6f649f4a
Any feedback would be greatly appreciated
