Th-plc biochemical process control system

　　TTh-plc fermentation control system, the control components are mainly composed of PLC, CPU, I / O board and operating computer (or human-computer interface), with the characteristics of centralized management and decentralized control. The control calculation and fermentation data collection are completed by PLC controller, and the whole fermentation process is monitored in real time by operating computer (or man-machine interface), and the data are sorted and recorded. PLC is the first choice of process control system for small and medium-sized fermentation system because of its high reliability and cost performance.
