Redundant PT100 Controller


Thread Starter

I looking for a unit DIN rail mounted to monitor 2/3 PT100's. One of the pt100 would be in control of the process. This PT100 would be monitored by the controler. If the active PT100 became open circuited or went out of range then the second PT100 would automatically switch over into operation over. An relay would also have to be activated. The relay would be wired to an alarm circuit.
