Hey guys I want to use a DEI 528 pulse timer to delay the signal from my H700 to turn on my amps.
My truck is a diesel and in the colder weather the grid heaters pull a crazy amount of power for up to 15 seconds. I hate the idea of all those amps powering up while the batts are pulled down to 11 volts.
I think ( instructions don't seem to show an example of what I want) I need to hook up as follows
Red ~ keyed 12v +
Black ~ ground
Black/stripe ~ signal from H700
Brown ~ signal to amps
Blue loop ~ uncut
Does this look right?
Also the instructions say its a 30amp relay but further down the page it says not to exceed 15amps????? So playing it safe will 15amps be enough to turn on 4 XXK amps? I cant find any info on what they draw.
TIA
SR

Man, when they rewrote these, they loused them up.

These instructions clearly call it a 15A relay.

Your amp RTO leads should pull far less than that.

Red is constant 12V, not switched.

Black is ground.

Black/white to start wire in column (activates 528T on start event, breaks RTO to amps)

Orange to RTO OP of H700

Yellow to RTO input of amps.

Blue loop cut.

Sorry to resurrect this but I didn't want to start a new thread on the exact same thing.

I have the same configuration that VP Electricity posted.

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

This would mean my amps would be on when my HU is off.

What am I missing here?

Thanks!
