DEI 528T ignition delay wiring question

**dbzeag** · 05-27-2006, 11:44 AM

So I picked up the 528T but I don't think it will work for what I have envisioned.

Basically what I want is the ignition line of my car to be delayed 45 seconds or so before sending the signal to my amp when starting. Then when shutting down to immediately to kill the ignition line, no delay.

Does anyone know how to wire the 528T to do this? Can this even be done with the 528T?

Thanks for any help.

That's how mine works, I have it hooked up as follows (i think):

red: PSU's +
black: PSU's -
black/white (trigger): remote wire +
yellow: remote wire + (any + really)
orange: amp's remote turnon

I tried wiring that and the orange line just goes to 12V instantly, no delay, no matter what setting I have for the delay timer. It works just like a bosch style relay now.

I have the red and black straight from the car's battery and to the car's ground, the trigger on the car's ignition wire, the yellow on the car's ignition wire, and the orange is what I am testing.

Have I done something wrong here? Thanks for you help. Also the brown line is at 0V throughout the whole test.

Sorry to play the resurrection card on this thread, but I have the same problem and it's holding up my install.

The Orange wire is ON from the start. A positive pulse on the trigger turns the the orange wire OFF for a delayed amount of time, then ON again.

Did you get this sorted out? Am I missing something here?

Thanks!

Could it be that this kind of relay is meant to turn on for a set time then turn off. Or vice versa.

could it be that the yellow wire is what is needed to be used for connection to the amp?

the main use for the 528t is for a deisel timer-- in cold weather, it takes a few seconds for the trucks glowplugs to warm up-- so the 528 is supposed to delay the remote start signal until after the the glow pugs have warmed up...

with that being said, i think that something is wired wrong, but i can't exactly narrow it down..

thinking out loud, but i will type this as i am going over the manual...

back w/ stripe is your trigger input-- ie: acc. line from key.

red and black power wires should be obvious-- they need to be connected..

orange says that it is for the normally closed output-meaning you should get continuity
across this and the yellow wire when the relay is 'off..

yellow is the common terminal-- i would prefer to put the constant 12v input connection here though(partially personal preferance).

brown is normally open-- meaning that this is the terminal that the amp should be connected-- this terminal should only be active when the relay is powered on.

the blue loop-- i think that this needs to be cut-- but i am really not sure..

I will try connecting the yellow wire to the amp and report back Soundman.

Thanks!

Any update from anyone?

I gave up on the 528T. It simply wasn't working right.
I found it actually easier to build this circuit for my application.

This is JUST a delayed turn off.

Yay! Someone that adds a circuit to a STANDARD relay.
IMO the best way to go.
IMO worth learning some basic electronics for.
But otherwise IMO better to stick with "standard" offerings like 528t etc.

M-Dub - you're a hero! (IMO)

PS - a resistor instead of the diode D1 means slow (delayed) turn on.
Reversing the diode (with a resistor in parallel with it) means delayed on and instant off (assuming the switched ACC signal goes to GND).
