Allot of times in industrial environments we get noise on the analog signal input to PLC’s or other controllers. The noise can be generated by motors, bad wiring, etc.
Placing a 1- 100 uF capacitor on the input signal and ground (common to the cabinet) will reduce the noise that the input is receiving.
