NiYo Engineers’ PID Control Trainer is designed to demonstrate P, P+I and P+I+D action and direct and reverse action in open loop mode. The PID Controller is electronic type. The input and output to the PID controller can be varied and measured. Effect of change of Proportional Band, Integral time and Derivative time is studied. The system incorporates the standard industrial components. This equipment is an excellent solution for understanding basics of PID controller.
