how much current does the relay draw in the on state lets say at 5V and 12V dc supply? can an arduino switch it directly?

Im not sure how much current the relay draws since i haven't measured it, but i have run the relay with a 5V standard GPIO directly without any adverse effects. This is with a Sanguinololu 1.3a PCB used in 3d printers. Essentially an Arduino.

It's just a relay so will switch anything you want. It's rated up to 120 V AC but will switch DC of lower voltage. Being a relay the switch is completely independent of the mains which is used to operate it. Hope this helps.

No, the coil that activates the relay is 120VAC - use R04-11D30-12 for a 12VDC coil and contacts that can carry 30A at 120VAC

I have not found anything. Just assume it's a 5V input, and output is inverted (High input = relay OFF)

You can just plug it in, the converter will only use what it can, I use this with 9V 3A to convert to 5V, the max current draw I measured is ~ 1.9A.

The 12VDC is only to drive the relay coils. Use the middle terminal (Common) to complete your circuit. You supply power for each relay. http://electronicsclub.info/relays.htm

this is a terminal block that can handle 12 volts with no more than 8 amps of current if you replace the current wires that come with it.they look like they came out of a computer or plone block. you could also hook your devices to relays and use the block to supply voltage to the switch side of the relay.

The output relay contacts are rated for a maximum of 10 amps at 30 volts DC - so, yes, this will work for switching LED strip lights. The overall current drawn by the 5 meter length depends on how many LEDs there are. As long as the total current is less than 10 amps, no problem. (And, the current to drive each LED is typically low, so it is probable that the total current is well under 10 amps.)

You cannot pass power directly to your device from the trigger side of the relay by way of the board itself, BUT what I did was solder a wire between the Positive (top most) pin on the trigger side to the Input (top most) pin on the relay side. Then I applied a piece of non-static film tape over the back of the board.

I didn't but its not a bad idea. how big?no less then 50amps with reset, it depends on how much you draw i don't think you need a relay

Based on the picture, this 2 relay shield already has opto isolators for both relays (that is what the two 4 pin modules are). Raspberry Pi uses 3.3V and this uses 5V, so you may want to use a level shifter (or an NPN transistor with two resistors) to keep from overloading the Pi output.

Correct. The relay is actually turned OFF ONLY at the zero cross point of the AC wave. It can be turned ON at any point in the wave depending on your needs, load, EMI requirements etc. So with DC it would turn on but not off (no matter what your control input) unless the DC voltage dropped to zero for whatever reason. Also It would likely NOT handle anything like the rated voltages(give as RMS) with DC load.

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.

12 vdc is required, if you lose power the configurations stays, i recommend you to use 3rd party relay on the output and do not use the direct relay output

I am using a standard power supply to operate mine - 5V on the power pins on the board (There is a jumper to set 5V or 12V on the board, everything works fine with 5V for me). With the power connected, I then use 4 input pins of the arduino to drive the motor, using the servo library, and everything works as expected. Let me know if you have more questions.

I would day it is best to use a relay, unless youuse aheavy dutyswitch. Most switches are not designed to handle a load running through them, even though these lights only use about 5 amps to run both.

It will work off any 12 volt power source.... So, if your Arduino can support a 12 volt power source to this switch it will work.
