In the process industry, safety and efficiency are the two most important pillars of the production process. Taking petroleum, chemical, metallurgy and other industries as an example, due to the huge investment in production equipment, harsh production process conditions, often with high temperature and pressure, flammable and explosive characteristics, these industries are more and more stringent requirements for process safety.

Another feature of the process industry is the continuity of the production process, and every stop will cause huge losses to the enterprise, so the process industry needs the safety system to have good availability.

Industry safety standard

N7K-M324FQ-25L  Safety controls in the process industry are designed, implemented and maintained in accordance with a range of international and national safety standards to ensure the safety of equipment and operations.

The standard covers multiple aspects from risk assessment, security system design and network security to ensure the safety and reliability of the process industry under various operating conditions. When implementing a security control system, enterprises must refer to applicable international/domestic standards based on specific application scenarios.

The king of price performance in market segments

As a well-known brand of safety automation, Pilz is able to provide high safety and high availability of products and solutions for the process industry such as petroleum, chemical, metallurgy, etc., to provide security for the process industry.

1. Emergency Shutdown System ESD(SIS)

ESD system is a part of SIS safety instrumentation system, in some cases people directly use SIS to replace ESD concept. The system is independent of DCS and has a higher security level, and can detect the safety of the device online in real time. Under normal circumstances, ESD systems are static and do not require human intervention. When there is an emergency, it can bypass the DCS system and directly issue a protective interlock signal to avoid the spread of danger. ESD system must meet the requirements of high availability, hot swap, and Ple security performance. The safety controller of Peel Magnetic is widely used in SIS system.

2. Isolation fence

The isolation gate is used to realize the electrical isolation between PLC and the actuator, protect the output loop of PLC, and ensure the safety of the control system. It is different from the concept of explosion-proof isolation grid, explosion-proof isolation grid is mainly used in explosive environments to prevent sparks and arcs, with explosion-proof certification, and electrical isolation grid is only used to protect the safety of PLC circuits.

N7K-M324FQ-25L  Direct selection of safety relay or safety relay expansion module as safety controller isolation gate, can achieve SIL3, has a very mature application in the process industry. A well-known domestic process industry system integrator, in a domestic chemical enterprise electrical instrument center project, used PNOZ S7 as the safety relay for SIS system, to achieve safety isolation grid control, the operation effect is very stable and reliable.

3. Furnace control

Furnace control includes burner and boiler monitoring, and Peel Magnetic products and services ensure the safety of the combustion process and monitor potential danger signals.

Pierre Magnetic’s burner management system monitors all functions of commercial and industrial gas and oil furnaces, from pre-purification to integrated operation of the main burner. Users can choose different controllers according to the complexity of the system requirements and the number of burners.

PILZ is a well-known German automation brand, the inventor of scram safety relays, and our products and services are used in a wide range of industries. In the process industry, safety is always the first priority, and Pielmagnetic solutions not only improve production efficiency, but also ensure the safety of personnel and equipment.
