Application Scenarios

Oil and Gas Industry: Used to monitor and control various safety-related signals in the oil and gas production process, such as emergency shutdown systems and fire and gas detection systems, ensuring the safe operation of the production process.

Chemical Manufacturing Industry: It can connect to various on-site safety equipment to realize the safety control of parameters such as temperature, pressure, and flow during chemical reaction processes, preventing accidents.

Power Industry: In power plants, it is used to monitor and control the status of equipment such as generators, transformers, and circuit breakers, ensuring the stable operation of the power system and the safety of personnel.

Pharmaceutical Industry: It ensures that the equipment operation safety and process parameters in the pharmaceutical production process comply with safety standards, safeguarding drug quality and production safety.

Operating Principle

Signal Input and Processing: It receives various signals from on-site equipment (such as status signals of sensors and operation signals of buttons) through 8 digital input channels, and then processes and analyzes these signals.

Control Logic Execution: Based on preset control strategies and algorithms, the module executes corresponding control logic, such as determining whether safety conditions are met and deciding whether to trigger safety actions.

Signal Output: If a safety action needs to be executed, the module sends control signals to external equipment through 1 digital output channel, such as controlling the closure of valves and activating alarm devices.

Communication Function: With the help of the Modbus RTU communication protocol, the module exchanges data with other equipment or systems to achieve information sharing and collaborative control. For example, it uploads the status information of on-site equipment to the upper-level control system and receives instructions from the upper-level control system.

Safety Certification and Guarantee: It has obtained safety certifications such as CE, UL, and CSA, ensuring that the module meets relevant safety standards in terms of design, manufacturing, and performance, and providing reliable guarantee for the safe operation of industrial systems.
