Great multi function relay

[angryblack]

Not sure if anybody has used these in a 12 volt app..But they re pretty common in the industrial field.. During my build i found one that is set for 12 volt operation..

I use it as a cool down switch to continue to run my fans after I shut the truck off.I plan on getting one to allow my tow pig to run after i get out to let the turbo oil not to cook

Ive seen them in grainger but not in the 12 volt form..Ive been runing mine for a few months and it always works..

On-Delay (Delay-On-Make)
Off-Delay (Power-Off Delay)
Interval
Switch-On Initiated Interval
(Single-Shot)
Switch-Off Initiated Interval
(Delay-On-Break)
Repeat Cycle

are all settings you can run with it.
Here is a pic on a small plate i installed in my truck.You can get an idea how large the relay is.The spdt relays control my fans,rocklights, and whatnot.I use a push button to start the timer in the relay
I will have to search around for the instructions and scan them.
