60 amp 12v timed relay source, suggestions

[moparguy]

I'm struggling here. Totally out of my element. I need to find a relay to trigger a 12v solenoid that has pull on winding with only a 2 second or so duty cycle, then a 100% duty cycle open set of windings.



I'm thinking both sets could be energized initially, then the pull on windings drop out after a second or two.



Would be great to do this with one relay. I've looked online and I'm not comfortable reading the specs. There's a very high likelyhood I'd order the wrong item.



So, if anyone has a vendor that can help, or can provide a specific item number or link to a relay, I'd be greatful.



Thanks, RR



PS; this is for a US Gear exhaust brake, I'd like to do away with the need for the factory control box and work it off a push-pull switch on the shifter.

Does the solenoid you are using have a duty cycle?



What is the duty cycle? 80%?

K, I really don't know anything beyond 100% duty cycle on the hold on windings and a 2 second or so time limit on the pull on windings.



No decernable name on the solenoid, but it looks exactly like the fuel shut-off solenoid on a 12valve with a P7100 pump except that it's about 25% larger.



Thanks, RR

So do you need a one-shot timer(pulse) to kick it on and another one shot to kick it off?

Would something like this work for you?

It looks like it uses a little DC gearmotor. Very simple operation but not very fast.

Listen to that Toyota/Lexus 2JZ-GE (NA, 3. 0L, DOHC, 24-valve, I6) sing!
