Hi,
Today all PLC suppliers have their own small "simple" PLCs(Siemens LOGO, Mitsu Alpha, Crouzet.....) with some few I/Os, limited expansion possibilities and a small display.
I work a lot wit hydraulics and most proportional valves need a +/- 0-10V signal. I have looked at some of these small PLCs but they only have 0-10V not +/-0-10V. Does anyone know a PLC with this type of I/Os.
