The CN132 digital microcontrollers include all the features of standard 1⁄4, 1⁄8 and 1⁄16 DIN microprocessor controllers, in a very small package. The CN132 features advanced autotune PID. Autotune teaches the controller the main characteristics of the process. Autotune learns by cycling the output on and off. The results are measured and used to calculate optimum PID values which are automatically entered in the controller memory. Optimum cycle-time is calculated by Autotune programs. The choice of cycle-time is inﬂuenced by the external switching device or load, e.g., contactor, SSR, valve. Each control parameter can be set by the user through the front keypad. These units include program security in a hidden level for OEMs.
