Pid controller?

Thanks for the info guys. I just ordered two PID controllers, two 40 amp SSR's and six thermocouples. I should be able to scrounge everything else from my garage to build two units. All in the parts were $90.32.
 
Managed to obtain PID parts off Amazon and have assembled the controller with ease. The PID,SSR and thermocouple came as one order but the thermocouple will be to short which I knew when ordering but the prime shipping made this a better deal. The PID is a Ink Bird ITC-106.
Unit powered up and appears to be functional. Due to my lack of or not having any electrical knowledge of the settings and what they do and how to use them for this applications is giving me some grief.
Initial observations are that when powering on the digital display comes on with PV higher than set value. I bump up the set value and just shy of a minute the will start outputting power. Once set value is met it will overshoot PV by a couple of degrees and take a minute to stop outputting power.
What I would like to see it do is to send power out as soon as I set SV. higher than PV with out the delay. As well as stop sending out power as soon as PV is met. Should I be able to achieve this.
Thanks

short answer is no. You can play with the proportional, integral and derivative values but that can be a shot in the dark.

Closest you will get is when you put it into "learn mode.

Sounds like you're looking for on/off control which most PID's can do. Read the manual and look for on/off control.
 
No looking to have it to start sending out power as soon as I set values and turn it on. And also to set it so if I increase SV that it starts sending power with out delay.
 
I think you will find it will do those things if you just let it cycle your device a few times. As a brand new hookup it has no data on dead time or heat capacity of the system it trying to control, so performance will be a bit erratic while it gathers that data. Once it has numbers to fill into the algorithm it should behave as you want. And yes, running auto-tune will speed the process along.
 
You can easily build your own PID by watching Johnny's Reloading Bench video on YouTube. That's how I built mine. Parts are readily available from Amazon. Mine works fantastic, now I'm building an annealer 🙂

Like AndrewM mentioned. Most people just build the PID to supply to a regular a power plug then crank the thermostat up to full on their pot so it doesn’t interfere with the PID operation.

That's the way to do it, so you can use the pid on multiple devices without modifications to each one.
