AT908 CD-Reihe Autotuning PID-Regler

Temperature Controller PID:Normal / Fuzzy PID Auto-tuning function for heating & cooling Output:Relay,SSR,SCR.4-20mA 2 alarm Self-diagnosis function. Free 4-digit measurement value setting. Every parameter can be shielded. Various inputspecification are available, including thermocouple, thermal resistance and linear signal etc.. Adopting modular structure output mode. Multiple output modular specifications are available, which can adapt to different application. Adapting intelligent PID control arithmetic without over adjust. The controller still has auto-tuning function. Be applicable with universal AC 85 256V SMPS or DC 24V power supply. Pre-setting emendation system (for input specification) inside. Freely switch between different input specifications. (various thermocouple, thermal resistance, linear signal etc..)High accuracy and stable control effect.
