Simple PID heat & timer
Posted: Thu Jan 29, 2015 10:23 pm
Here's a rather simple PID controller that I set up over the past few days.
Here are the components:
Auber Instruments SWA-2442C - 1/16 DIN PID Process Controller w/ Timer & Alarm This controller has 10A relay contacts, most blankets run 5-8A so no solid state relay is required.
Auber Instruments TC-K5 - k Type Thermocouple, Bare
International shipping to Canada was $12 US
The on/off switch is just a basic house switch.
The single plug I pulled off the non-working router speed controller I got years ago from John Hall, so is the power cable.
Here's the schematic I used, thanks to Dave Fifield
You'll notice in my actual wiring job that I jumped post 11 & 12. This needs to happen in order for the timer to be enabled.
Total cost to me was under $100 CAN. Took about 2 hours to fully set up, including slight modification to my bender base. Took another 1.5-2 hours to figure out the "programming".
I like this controller as it controls both the temperature and has the timer built in. Works like a charm!
The rest is pretty easy.
