PID Controllers Exploit Fuzzy Logic

Using firm's state-of-the-art fuzzy logic, the PX Series of fuzzy logic controllers comprises nine PIC autotune controllers that allow a process to reach its setpoint in the shortest time possible while virtually eliminating overshoot. The controller's action lets a process be maintained at a steady setpoint. With a NEMA 4X faceplate, these controllers can withstand corrosive environments, hose-directed water, and wind-blown dust and rain. Controllers accept a wide variety of inputs and eight-segment ramp/soak programming. Advanced security options prevent unauthorized use and all parameters are display-maskable. Standard power requirement is 85 to 264 vac with 24 vac/vdc optional. Two outputs and programmable alarms are available.
