I've used a version of this part with spade terminals for the load on top of the package (datasheet says '.250" (6.35mm) quick connects for contacts', see the part number decoder there.)
When working with a high voltage AC load, I'd definitely prefer & recommend that version of the part, as it allows you to keep the hot connections entirely isolated from the PCB.

Are these coming back in stock soon? Hope so -- I have a project waiting on them.
Thanks!

Need more relays.... please?

These are great. I would like to see a DPST version of this for U.S. 2 phase 240 volt circuits.
The PCB you stock for this isn't so good though, aside from the pins not quite lining up, the traces are not near heavy enough for even 10-12 amps @ 120V continuous.
Even if it had a simpler way to add heavy jumpers would help.

Can these be used in the UK with 230VAC?

Anyone know the maximum voltage which would be safe to use on this. I see that its a 5v relay, but if i use 6-8 will it be ok?

For 220VAC use, it would be great to have a DPST-NO relay - that way both hot legs would be isolate when the relay was off (open), rather than leaving one side hot.
Any plans for adding a 220VAC@30A DPST to the product list?

I am pretty sure the IO pins on the Arduion output at 40mA per pin actually. http://arduino.cc/en/Main/ArduinoBoardDuemilanove
From the above link:
They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.
These work off of 5V no problem from my experience and I have them setup and working on my Arduino. I built a few of the boards detailed on your Controllable power outlet tutorial here (http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=119)
I've looked at the datasheet and I'm confused by the coil data tables. The arduino can switch a few of these no problem. I'm wondering if it can switch 8 or more?

Looking at the spec sheet I can't find how much power this draws. I'm trying to figure out how many of these I could turn on at once from the Arduino.

Anyone have any ideas how fast this relay can be switched? Max. frequency of ON/OFF. I tried looking at the specs, but for the likes of me could not find any numbers..or am I just blind. Any help appreciated!

In the tutorial they use this relay to switch an AC load. I want to switch a 12V DC load that needs about 10A. This would work to switch a DC-powered load, right..?

I read the datasheet and comments, but still wonder if this is the right part for my application.
I want to hook this up to switch power to a dc subpanel in my car. So I want this to close when I turn on the ignition (I have a switched wire to tap into), and when it closes, it completes a circuit of heavy wires hooked up directly to the battery. I see discussion about 5v and 12v to activate this relay, so that's really my question. Thanks!

Landonr: Hi, I just bought this relay, do I need to buy the pcb also to use it with my arduino or can I use it alone?
you could definitely use this alone... refer to the tutorial posted above. the basic 2 transistor switch could do the job.

Can i use this on a 1HP air conditioning?
here is my aircons specification:

I'm not good with the calculations regarding the increase current during startup. This is why i am doubting the specification of 30A-240V. it can be seen that my air conditioning is jut 4.18A.
Can anyone assure me to use this? :D
TIA.

Hi, I just bought this relay, do I need to buy the pcb also to use it with my arduino or can I use it alone?

Can anyone tell me if this relay works with 9V from a wall outlet? I've tried, but no luck. Thanks!

Sorry about that! We have switched to the 5V version. We should have cleared out all the previous stock. Contact customer service and they can replace that relay for you.

You says is a T9AS1D12-5 (coil 5v) but image is a T9AS1D22-12 (coil 12v), and you have send to me the T9AS1D22-12. Tutorial is referred to T9AS1D12-5, but you are selling T9AS1D22-12.
