Certification: Complies with SIL3 standards, features CE marking, and has passed ATEX and IECEx certifications.

Application field:
In the petrochemical field: It can be used for precise control and safety monitoring in the petrochemical production process. For instance, in the temperature and pressure control of the distillation column, the opening degree of the regulating valve is controlled by outputting a 4-20mA analog signal to ensure the stability of process parameters. It can also be used in the emergency shutdown system of chemical plants. When a dangerous signal is detected, it promptly outputs control signals to close relevant valves and equipment to ensure production safety.

Power industry: It is suitable for the automatic monitoring of power systems, which can be connected to various sensors and actuators to monitor and control parameters such as the speed, voltage and current of generators. It can also be used for the status monitoring and control of switchgear in substations to ensure the stable operation of the power system.
In the field of fire and gas detection: It is often used as the main interface for on-site equipment related to fire and gas detection and suppression. It can be connected to smoke sensors, combustible gas sensors, etc., to collect detection signals in real time and transmit the signals to the control system. Once a fire or harmful gas leakage is detected, the corresponding alarm and fire extinguishing devices will be activated in a timely manner.

Valve monitoring system: It can be used as the interface of the valve monitoring module to achieve digital output control of solenoid valves and analog input monitoring of valve positions. For instance, in the control of water gates in sewage treatment plants, the opening and closing degree of valves can be precisely controlled, and the position information of valves can be fed back in real time to ensure the normal operation of the water treatment process.
In the field of numerical control machinery: Sensors and actuators that can be connected to numerical control machinery participate in the position control and condition monitoring of machine tools. By connecting devices such as encoders, the position information of the machine tool’s worktable or cutting tool can be obtained in real time, achieving precise positioning control and improving processing accuracy and quality.
