I need a list of manufacturers of PLC redundant controls for a mechanical fin press, the control must be able to be programmed to do gag routines and multiple fin lengths.

 

What are you looking for? HW / SW or a complete system?

If its HW Mitsubishi A2 series will handle it with ease.

If you need safety to machine code regulations try Pilz ( Germ. & US ) or the new Siemens PLC to class 4

 

I know that Square D and Modicon have PLCs that are used on presses. Try calling Square D's Press Group in Troy Michigan.
