Description
The SY311 is a compact thermal control module designed for hands-on study of continuous and discontinuous feedback control loops. It features a unipolar electric heater with integrated temperature sensor and fan motor, housed in a transparent air channel for direct visual observation of the heating process. The module is equipped with dual integrated power amplifiers enabling multi-input control strategies such as Fuzzy logic control. Built-in disturbance mechanisms allow realistic exploration of process perturbations.
