Hello Robin,
If 180 bucks are ok with you:
I like the Siemens Logo unit 12 inputs 8 outputs
There are including versions with analog inputs.
They programmed by logical blocks.
Only thing the cable is expensive.
Get yourself the demo version 2.0 for free
and I email you the missing files to make it work completely.
Another cheap thing is Telemecanique Zelio.
Its faster but less inteligent. for the same price.
Have fun
Sven Peter
