As I understand, applying 12VDC will turn on the relay to control 12vAC for a set time and then off. This trocess will repeat next application of 12V

No, 12vdc is always required on to power the circuit. There are 2 pins that you wire to a simple push button ( must be momentary, not a switch. Like a doorbell button) once you push the button, the time will start. This closes the relay contacts. You use the relay as a switch to control what you like - this can be whatever you like (limited by the relay rating of up to 10 amps 250vac or 10 amps 30vdcYou must supply this voltage independently, unless it's 12vdc, then you can use the same supply voltage to the timer. The timer runs its cycle until the next time you press the button

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

This unit will supply power, when triggered, for a time period that you can adjust. I use this to run a 12v dc motor, my trigger is a electronic timer that triggers this unit to run for a preset time. Hope this was helpfull.

Yes, it requires 12 DC to operate. I have it connected to the 12 volt source through one of my console switches.

Yes you can inject the starter relay with voltage and the starter should turn over. This tool will inject ground and voltage into any 12 volt DC system

You could wire up switches to control each relay. You would supply 5 volts to the corresponding pin for a given relay you want to activate via individual switches. But the best use for this board is to let an Arduino or similar micro controller operate it. That is its intended usage.

I used it to control a 12v powered water valve remotely. Probably depends on the amp draw of your setup ... but if it was a higher draw than the remote handled directly, just put a 12v relay in the path to handle the amps/

In a portion of my design (trailer wiring system), I have a 400 Watt DC to AC converter which connects to a AC wall outlet in my trailer. I have a trickle charger hooked up, so not many watts drawn. This has worked for me so far. The main wires going through relay end up having AC power through them. The actuator in the relay is controlled by magnet (and I still use 12 volt to control relay), so the magnet portion of relay doesn't make direct contact with AC power. Can't say for sure on 24 volt if it will work, since I still use 12 volts to actuate magnet in relay. I actually disected a relay to see how it worked before building my system. I hope this helps.

I didn't like the heat so I cheated.I used a 10,000uF capacitor in parallel with ~10 ohms in series with the 12V and valve.This allows the full 12V available to pull in the valve, but then drops the current by around half, reducing the power to ~1/2 of normal.I was afraid to let the valve operate for more the about ~15 minutes with 12V.Do a net search for fast relay operation or reducing relay power consumption for some examples.Good luckTerry

Pretty Simple. There is an input VCC and Ground and once that power applies it waits an x amount of time (based on the potentiometer) to actuate the relay. The relay has a COM (not connected to Ground) and a normally open and normally closed switch. Anything specific that you need help with?

The 5 V is for signaling ( which relay will be activated? ) the other one 12 V for relay supply. It goes to the relay supply.

I'm not really sure what you're asking, but this device is only capable of raising voltage. If what you mean is that your 12 volt system is rated to say 5 amps and you want 10, no, this cannot do that. In fact, this can only LOWER current while RAISING voltage (remember, P=IV and V=IR).

The device you control does NOT have to be 12 volts. This controller is powered by 12 volts, but simply closes relay contacts (switches, if you will) to control any other voltage/current within the specs. It is NOT a controller for 12 volt devices, though it can do that.

1-Yes the relay switch is controlled by 120 volt and is separate from the switch sides.2-Yes the switch sides are independent from the relay power side meaning I can control a 12 volt item using 120 power to the relay.3- Is there 2 switch sides? Meaning can I send 120volt into relay switch side and switch 2 separate items on and off like a 12 volt and 120 volt independent but with same relay With the option of normally closed.

I use this relay on a 12VAC circuit. Works great. I think there is a small diode in series with the coil , so the coil would be DC. Check the one you have it might be the same.

Hi, the switch you mean the contact? The timer power suplpy is 12vdc. But you can manage 12, 24, 110 v etc only taking care of your load.

The relay is a basic low cost 12VDC relay. I used mine on my car horn in which it is damp continuously. If this is for a critical system buy a more expensive 'sealed" 12VDC relay. If its not on a critical system but under tank, or seat, just put a thin layer of epoxy on the cap to seal the unit. Install where the relay in the position with contacts facing downward. Use Dielectric grease on the electrical terminals before connecting them.
