how much current does it need to trigger the relay?

Whatever amps car key switch give works great to start most big relays Use a battery charger to start it, that should show the amp draw

Hi....the continuous holding current is 0.7A....I would make sure the trigger circuit is capable of at least 1a

I don't know the minimal current necessary, but mine triggers with 12v when hooked-up to my truck battery.

Nor sure how much current to activate but I set mine up to operate heater on a van so that power was not routed through fuse block and stopped the overheating. That circuit is 12v to run the blower motor, but I don't think it needs that much because it really snaps the relay when I turn on the key.

I dont know, it depends on if your high beams are switched on. It takes power from the high beam signal to trigger a relay and that relay will feed power to the low beam elements. Hope this helps. Tim

You MUST use a relay. The negative trigger cannot source the required current to trigger the door solenoids. You risk damaging the unit if you don't.

Just found this out.If you go to the page on Amazon where they sell the relay and go down to the 5th photo there is a basic schematic.It shows that the pulse wire to active the relay is 12V+ which you need anyway to power the timer.One of the reviews also talks about this as one person wished the pulse could have been 12V-JW

no, when power is applied, it will count down the set number of seconds then activate the relay.

If I understand your question there are a couple of ways to do this. Since the timer is going to power the relay there will be no issue with amperage draw. The relay doesn't draw appreciable current, it's just a relay. One way to proceed is to install the timer "upstream" of the lighted switch. In this approach you wire the timer into your 12 volt system (remember a fuse or breaker and check the ampacity of the wire) your timer becomes the source of power to the lighted switch and in turn the relay. Of course the heavy load that your relay controls remains wired as it always has been. Should you wish to shut down the heater for a long time you can simply turn off the lighted switch and ignore the timer. A second approach would be to remove the lighted switch entirely and simply use the timer as the power source for your relay. Again just for the switching, not for the load. These timers can be programed but they also have a manual function so you can over ride the programming and turn your heater on manually should you choose.

Switch is NC to ground. Do not know exact current capability, but surface contact area on switch is pretty small so my guess is 2 to 3 amps max.

no relay is required. My shop guys installed it with no problems direct to the power source

I have used solid state relays for heavy loads. Make sure your electrical load does not exceed the capacity of the relay. Two relays should be used for a 220 VAC power source. One for each power leg. Turning on both relays at the same time is no problem. On the other hand, I'd prefer using a 2 pole mercury relay that usually has a 120 VAC coil. Grainger carries such a unit. example: Item # 12N674 www.Grainger.com

I didn't use any relays, since they are LED the current draw is low, If my math is correct, each light draws about 1.5 amps.. I'm using them as back-up lights for my 2003 Ram 2500.

The type of load shouldn't matter. I have not tested it but I see no reason why it wouldn't work. This relay operates exactly like a mechanical switch.

I do not believe this will work for your application. I don't think relays will respond correctly to only 6 volts

This relay is activated by a 110 volt signal on its own cord. I have been using them to relay both 220VAC on a 30amp breaker and 110 on a 20 amp breaker. They work quite well. Any system that will switch the 110VAC on and off can operate this unit. Hope this answers your question. Alan PS if you have a system that only has dry contacts you would need another relay for the 110VAC to make this work and at that point, you would be running a relay with a relay and that doesn't make a lot of sense.

That depends. The 12VDC power supply that you use must have the current capacity for operate all the relays (Assuming there is the potential for all 16 to be active at once) I don't have a relay board available to test, but would guess the coil current to be about 50 mA. x 16 that means I'd expect the board to require at least 1 Amp with overhead. The Arduino plus any other users on the bus have to be added so I'd use at least a 2 amp supply to run the system.

No you do not need a relay.Just hook the positive or + terminal on the gauge to the + terminal on the right battery and the - terminal on the gauge to the battery directly behind the one where you hooked the + to.Hope this helps.Coy
