Precision Digital’s temperature controllers accept a wide range of temperature inputs and use advanced auto-tuning PID control with ramp and soak capability to keep your process temperature exactly where it needs to be without the inefficiency of typical on/off relay controllers. Relays and 4-20 mA analog outputs allow these controllers to manage heating, cooling or both, or act as limit controllers. The controllers include all common digital panel meter sizes, such as 1/16, 1/8, and 1/4 DIN.
