Auberins SYL-2342 and SSR's?

[OldDirty]

Through a mighty brain cramp, I accidentally ordered an Auberins 2342 for my E-Biab setup instead of the 2352. Can I use the 2342 to cycle the 2 SSR's I have? I'd send back the 2342 and get the 2352 but if the 2342 would work without issue then I'll stick with it instead.

The 2342 is for relay output only. If you are going to use SSRs you need to have the 2352 controller.

You can use relay output PID with SSR. you just need an any DC power supply with output voltage in 5- 24 range. For example chsrger from an any old phone.

Just connect it inline with relay output and SSR.

How about a rough schematic that I could use?
I have a bunch of DC power supplies lying about.

Would something like this work?

 

[Brumateur]

yes exactly. Just don't use 3v power supply. Not all SSRs work reliable on 3Volts.

Thanks!

Isnt the switching speed reduced in the software for relay mode?

 

[Brumateur]

You can set the same 2 sec cycle time for relay output as for SSR.
Electrical lcontac life is much (up to 100 times) shorter than mechanical. So short cycle time is not good for relay when it works under load. SSR connected to relay create virtually no electrical load. So you will have around 1 million cycles life. It's approximately 1000 brews.

Good to know, Thanks for the explanation.

Finalized and electrically tested my control unit using the Auberins 2342. Everything tested out perfectly with my DVM. I then subjected the unit to a use test with 9 gallons of 65* water. The PID brought my keggle up to mash temps and held them without issue. Today, I placed the PID into auto tune and it dialed in to my equipment without a flaw. I then replicated a brew day. Walked through all the steps from protein rest to boil without an issue. Thanks for all of your help Brumateur!

I made a minor change to my diagram. I connected the negative lead of my 12v 500ma DC charger to pin 4 of the SSR. I then connected the positive lead of the DC charger to pin 7 of the PID. I then went from pin 8 of the PID to pin 3 of the SSR. I did that since I'd rather switch on the electrically positive than the negative.
