What do you guys think about this Extech PID (48VFL11)? They look to have similar functionality to the Auber PID (SYL-2354), but I just wanted to make sure I wasn't missing something.

Ive used a lot of controllers in my day and that one is a pretty simple one. depending on what you want to use it for it should work fine. just be aware of the output specs so you dont try to drive something with it that will blow the output. you might need to run an isolation relay between its output and device being controlled.

Planning on using one PID for a 4500W element in a BK/HLT and one PID for a 2000W element for my RIMS. Will have 40A SSR between PID and heating elements.

What the control input to ssr specs. You only have 20 miliamps at less than 600 ohms impedence on output of pid. You need to make sure the ssr control inputs dont exceed that. If they do isolate it with a relay and seperate power supply.

If they do isolate it with a relay and seperate power supply. It is usually a good practice to isolate it anyway to save pid from spikes etc.

So it looks like both Extech and Auber PID's have an output mode of 12VDC. The SSR I'm planning to us is a Auber 40A, which has a input of 3-32VDC. Looks like I should be OK in regards to the SSR control inputs. Thanks.

As long as your ssr is inside the current limit it should be fine. You can have a 12vdc output from pid and a 12 vdc input to ssr but ssr could have a 30milliamp min draw which will blow a 20milliamp output of your pid. Id check that as well.

48VFL11 ....1/16 DIN Temperature PID Controller with one relay output
48VFL13 ....1/16 DIN Temperature PID Controller with 4-20mA output
96VFL11 ....1/4 DIN Temperature PID Controller with two relay outputs
96VFL13 ....1/4 DIN Temperature PID Controller with 4-20mA output

The model# you selected appears to have relay output - not SSR control output.

Are you sure that's the one you want?

Dang, I already ordered this PID. I'm new to electronics and thought relay output included solid state relays. Did a little more looking into it after your post and saw relay output does not refer to SSRs. Was Trying to use one of my companies approved vendors rather than getting Auber approved. Guess I'll need to send the PIDs back. Thanks for pointing that out.

Sorry i should of saw that on data sheet. If you have an external power source to drive the ssr you can still use it though.
