12V 30A Time Delay Relay (10-Second Delay-On) – 5-Pin SPDT Automotive Relay for HID, LED Light Bars, Fuel Pumps, and Accessories

Works well for delayed air compressor power up. I did run it through a second relay to avoid burning it up.

My LED bar on my F250 truck was having failures in the LEDs. The manufacturer replaced it but the same thing continued to happen. After some investigation it turns out that when the engine is starting the batteries surge causing the LEDs to age. The LED bar is connected to the battery with an automotive relay but it engages as soon as the starter is engaged. Adding this 10 second delay should fix the surge problem. The relay was a drop in replacement for the one that came with the LED bar.

I bought this relay to switch on an external hard drive 10 seconds after the computer is turned on. It’s easy to wire up, the connectors are firmly in place and the price was very reasonable.

Bought 2... One was defective out of the box (continuity between normally open and closed terminals). The other worked maybe 1 in 3 times, I returned both. Save yourself the hassle and DON'T BUY THESE RELAYS!!

This relay (I bought a harness for the relay as well) is perfect for accessories I want powered on my motorcycle. I have items like my Auxiliary lights connected to the output of this relay. It allows my 10 seconds to get my bike started before there items come online and start drawing power. Works great. IF I need longer, I just cycle the kill switch and get another 10 seconds

Used as a control relay for a circuit that we need to activate after vehicle starts. 87A is “on” for the first 10 seconds then turns off, terminal 87 is “off” for the first 10 seconds then turns on… In our application only using the 87 to turn on circuit after vehicle starts..

Got this relay to turn on my speedhut hot rod gauges after I’m done starting my car as my gauges might glitch during the voltage drop while starting up. This relay is a standard 5 pin and I timed the delay which was 10s dead on basically. All wiring in past reviews are incorrect and I’m going to provide the correct wiring for everyone since I have it. 4 stars bc it works as stated and seems heavy duty with a solid click in the relay. But no diagram or pigtail is included (which I knew). Time will tell how it holds up. Pin 30 = constant 12v power (battery) Pin 85 = relay ground Pin 86 = 12v trigger to activate relay and timer Pin 87 = normally open (12v applied till after 10s) Pin 87a = normally closed (12v applied once trigger 12v applied to pin 86, power to pin 87a expires after 10s and switched power to pin 87) The relay is setup specifically for 12v switching as dictated by the 86+ on the relay but you can also swap 85 and 86 and put ground/negative on the 86 side and switched 12v trigger on the 85 side and the relay will still trigger but you will be sending ground/negative from pin 86 to pin 87 and 87a. Essentially whatever is connected to pin 86 gets transmitted to pin 87 and 87a. So you technically could use this as a negative trigger relay but I haven’t tested this but it’s possible with all 4 and 5 pin relays as I have done that in the past. Hope this helps!

I used it for electric fans to trigger a low-voltage relay and it seems to do fine

Très bon produit 👌 👍 Retard de 10 secondes. Attention lorsque l'on parle de 30A cela correspond à une intensité de pointe pendant quelques secondes et non du permanent, donc un usage entre 10 et 15A. C'est un module électronique donc il faudra respecter la polarisation (produit protégé pour les inversions).

NO SIRVIÓ !

Prezzo elevato ma qualità eccellente

Been using it for my FASS system in my diesel pick up, been working very consistently for acouple weeks now, I did take an average time and it only delays for 7 seconds not the full 10 but it’s consistent is the main thing. Just know walking into it it may not have the full 10 second delay but I think for the money it’s a good buy for sure

I misread the description. This was a 10 second delay for turning on. It does exactly that. I thought I ordered a 10 second delay for turning off. My mistake.
