REX-C700 temperature controller
Digital temperature controller features
1. Thermal resistance or thermocouple input and measuring range both can be set freely.
2. Softwareadjust zero and full scale, temperature measuring of cold-end alone, amplifier constant-zero, display accuracy is better than 1.0%FS.
3. The method of fuzzy theory combine with the traditional PID makes the temperature be controlled quickly and smoothly.
4. The method of advanced PID parameter self-tuning saves a third time as compared with ordinary instrument.
5. The output signal is optional: relay output, DC12V driver solid state relay, 4-20mA current.
6. Alarm output: two circuit user-defined alarm output.
