PID Controller with analog remote setpoint


Thread Starter

ABB have a line of controllers...C300 series that have operator panel selectable remote or local setpoints along with a whole bunch of other
neat features. We have several of them and they are a terrific controller. However......the membrane keypads they use for the operator panel is terrible.....I have to replace them every 6 to 8 months at $120 a pop. The keys stick and the unit starts to scroll through the different menus all by itself......then of course you cant get in to change values....the controller still works but you are locked out! I am told by the rep that they are supposed to be addressing this problem but until then, they are pretty expensive to have around
