Hi
I need a PID controller with the abillity to adjust setpoint remotely, with a 4-20Ma current. (Industri standard)
I've got a Siemens LOGO PLC and a lot of modules from a friend, but it can't PID. It's probably the smallest device that can be called a PLC. So I need the external PID controller.
I've searched the net for hours, to either find retired products or insane expensive ones. I can't use he ones that need the SP sat by keys.
Any of you, knows an affordable PID controller with such a property?
Thanks.
Lars
