Hi everyone,
I have a one-off personal automation project that I have been sitting on for a few years - an air compressor controller, consisting of a 240V contactor, two air solenoids, and a few buttons/lights in a box. I was wondering if anyone knew of any cheap DIN rail mounted Arduino (or similar devices) with 24V digital IO? I am familiar with the Click PLC being about $70 plus the cost of a programming cable ($20). Being an EE and embedded programmer I know arduinos can be bought dirt cheap and are "reasonable" for simple personal projects like mine. For ruggedness, I am hoping to find an enclosure and/or possibly a special purpose arduino-like PCB that has IO built in already. -- Jason White -- http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist |
Few options:
- Get a couple of these and mount to an Arduino case, or even a blank plate... https://www.mini-box.com/Din-Rail-mounting-kit-for-M350 - Many DIN rail plates on thingiverse (so you can 3D print one) - You can get universal DIN mount plates (even on Amazon) 24V I/O is then a separate thing though.

Many options exist and a quick google will net several to choose from.
Here's one I just tripped on: https://circuitdigest.com/tutorial/an-overview-of-plc-and-various-arduino-plc-boards To me, it's a bit of a mess and the choice to make is based on economics of development time and long term support rather than purchase price. There's a fairly large existing support base for real PLCs in industrial settings. Arduino... not so much.
