dang i installed the wrong pid again!!! help
 
so i bought the aubrins pid with the relay output not the SSR and i own an SSR.. i already installed it, havnt ran it and there is no wy to return it what can i do? im running a 1500 W element. i have had nothing but issues with the pids. im sick of it. could the element be underpowerd by th pid?

nothing yet?

What are you controlling the temp. of? Do you really need a PID/SSR for it? 1500W can run off an A419.

Otherwise, yup, better get another PID.

No offense, but it sounds like your issue has more to do with attention to detail than PIDs. Auberins sells a generic SSR/relay PID, dedicated SSR PID, and dedicated relay PID.

Have you tried contacting them to see if you can exchange it for a generic SSR/relay PID or dedicated SSR PID?

If you plan to keep it, I believe the PID you purchased has a builtin 10amp relay that will support a 1200 watt element. You can always use the internal relay to control the external PID, but the switching rate will be limited to a ~5 second cycle. A 5 second cycle is more than adequate for controlling an HLT or MLT but won't work well for a BK.

Hope that helps...

You could use it, just need to get a DC power supply and run the positive bias through the normally open relay contacts and to the + side of the SSR, then connect the - DC bias to the SSR. Probably could get away with a cheap wall transformer to test. It could click away like a sob though. If you're stuck with it, wouldn't hurt to try.

well its just for a herms set up. im only controlling the temp of like 2.5 gal. no big deal the coil is through a cut down corney with a heating element.. i just am so tierd of spending money on this damn pid crap.. im mad too because if you read the bottom of the description it says i can use a SSR but then i ordered it and mounted it. the stickers on the side are screwed alittle so there is no chance of a return.

damn i read the pid i bought again and well my fault... can you guys point me to exactly what i need? i could always use the current pid for a fridge. lame though

This one or this one.

Ha...I can see it now - Guys, I installed a PID on my converted fridge and the compressor burnt up a week later. :D

Using a PID to control a compressor is a bad idea...

All you need is a small 9 Volt DC wall wort supply. I will draw up how you connect it later. You see, the version that is designed for the SSR puts out 10 volts DC to turn on the SSR. On your version of the PID you have a simple relay contact. All you really need to do is provide your own 10 volt DC source (the 9 volt DC walwart, 9 Volts is enough to turn the SSR on) and switch it with the relay contacts on your PID.

One more option:
Get a new SSR with a 120V AC control voltage.
This way no DC supply is required.

You can use a PID as long you don't use it in the proportional mode.
