A little temp controller help please!

post #1 of 6
Thread Starter 

Good morning!

 

I am new to smoking and the forum, so bear with me if you can.  I am doing a fridge conversion and am at the point where I need to get my electronics figured out.  I am going to have a temperature controller hooked up to a ~1400 watt element. I will also have a convection fan as well as an inline exhaust fan to clear the smoke when it is time to open the door since I will be running this in the garage.  Those will most likely be powered separately.  

I did some research about temperature controllers and pulled the trigger and bought a Love 26150 temperature controller.  It seems like it has a little more than necessary for this application, but I got it for a good price so I went ahead with it.  I had intended to use a SSR, however after buying the controller I realized that the model I had gotten had an output that read "Proportional Current: 0-20 mA DC, scalable into 600 ohms maximum.".  I am not very good with electronics, so I wanted to ask what exactly this means for me?  So with this kind of output, what are my options for moving forward?  I did try and research about this, but didn't find any solid information. 

 

Here is the link to general specs and the manual:

 http://www.dwyer-inst.com/Product/Temperature/ProcessControllers/Series2600#specs

 

Most of the information about specs and the wiring set up can be found within the first 6 pages of the manual.

 

Thank you in advance for any help,

I have done some more research and have found two potentials thus far.  

 

I found a SSR with 4-20mA input: http://www.amazon.com/4-20mA-28-280V-Phase-Solid-State/dp/B00O9YLVGK/ref=sr_1_2?ie=UTF8&qid=1415524485&sr=8-2&keywords=4-20+mA+solid+state+relay

 

Or a PCM module that converts 4-20mA to proportional power control. http://www.omega.com/pptst/PCM3.html

 

Does anyone know if either of these would be ideal options?  I'm am sorry for my lack of electrical knowledge.  

 

Thanks

I looked at your controler manual. In order to figure out the specific controler you have you need to look at page 4 and use your model # that will tell you for sure what outputs you have.

I have the current 4-20mA up yo 600 ohms output.

I would go with the one you linked on amazon. I think that should work.

Check your PID and see if it also has a DC voltage output.  This is the type of output to use with a standard type SSR.  This type of output is either ON or OFF

 

If it only has a proportional current output then you will have to use something called a control relay.   A control relay is just an SSR that is compatible with the current control.  This type of output is proportional or variable, not full on or off, but a variable percentage depending upon what is needed.

 

Attached is a file that does a pretty good job of explaining.

 

Hope this helps,
