Does anyone have any experience with any of the following controllers?

Siemens "Logo"
IDEC Smart Relay
Telemecanique "Zelio"
Mitsubishi "Alpha"

I'm particularly interested in the stability of the ADC if I use a
0-10V dc input signal.

Being a complete PLC novice, I'd welcome any comments on good/bad
experiences with different makes.

Thanks

Another one for your list is the Crouzet Millennium range. I have used
these - both their mains and 24V volt range for various control projects
including domestic (heating, lights, ventilation etc). Very easy to
program. I don't have any specific info on the performance of the ADC (only
available on the 24V version) but their UK office are very helpful with
advice. see www.crouzet.co.uk.
