The 7400213-100 safety termination board is a safety terminal board manufactured by TRICONEX, a company based in the United States. TRICONEX, which is affiliated with the Invensys Group and later acquired by Schneider Electric, specializes in providing highly reliable safety instrumented systems for industries such as oil, natural gas, chemicals, and energy.
Functional Purpose
As part of the safety instrumented system, it is mainly used to connect field devices and control systems, playing the role of signal transfer and processing. It can accurately transmit signals from field devices to the control system and send output signals from the control system to corresponding field actuators, ensuring the safe and stable operation of the system.
Working Principle
It is usually used in conjunction with other TRICONEX modules and works based on the Triple-Modular Redundant (TMR) architecture of the TRICON system. This architecture consists of three identically safe system channels, each independently executing the control program. A hardware voting mechanism votes on and diagnoses digital inputs and outputs. The 7400213-100 safety termination board is responsible for signal access and distribution, ensuring accurate signal transmission between channels. At the same time, it participates in the system's diagnostic process, enabling timely detection and feedback of faults in aspects such as line connections.
Product Features
It has high reliability and can adapt to harsh industrial environments such as petroleum and chemical industries; it has good electrical isolation performance, which can effectively prevent signal interference and ensure the accuracy of signal transmission; it adopts a standardized design, facilitating installation and maintenance, supports online repair, and allows removal and replacement of faulty modules without interrupting process control.
Application Fields: It is mainly used in industrial fields with extremely high safety requirements such as petroleum, natural gas, chemical industry, and energy. It is used to build safety instrumented systems to monitor and control key process variables, ensuring that the production process operates within a safe range and preventing accidents.
