Industrial Intelligent PID Temperature Controller 72*72mm SSR or Relay Output The instruments of this series are double-row four-digit display intelligent instruments, which display measured values and set values respectively. They can input a variety of signals. The instrument is equipped with four-button operation, easy parameter setting, and convenient information input. The control method has two-position control and PID control. The instrument adopts super anti-interference chip design, and the quality is reliable. The control modes have PID control and position control (also known as hysteresis control or upper and lower limit control). PID control is a professional control method suitable for industrial control situations requiring high-precision measurement control. PID is short for proportion, integral, and differential. PID control combines the advantages of the three and has the function of fast and timely proportional action, the ability to eliminate residue with integral action, and the advanced control function of differential action. In addition, the self-tuning function of the meter can automatically calculate the optimal value of the PID parameter according to the control effect of the controlled object and automatically save it.
