PI and industrial interfacing

Hi

Does anyone know if there's a good low cost board for light industrial use on the the PI that does PWM, 24V, 0-10V, 0-20mA / 232 etc?

Thanks Boss! I'd not seen those, they look interesting.

Hi Keith, I have not found anything exactly as you describe, the best I found was on Kickstarter but it has not delivered yet (due Jan 2019) and now closed I believe to new customers, but it may become a product.
The other thing I did look at is the pMod units, there are many options available for these.

Plus a hat for Pi and shield for Arduino.

My thoughts in the past were an Arduino interfacing to the pMod as it allows you to be closer to code without an OS in the way and the Pi as the main user interface with touch LCD etc linked to the Arduino.
This has all been a mental exercise so I have no idea how effective it would be for a real application, but it would certainly be versatile and configurable.
Andrew Back and Ten22 both did articles on the Pi and pMod which stimulated my interest in pMod approach.
