TRICONEX 3502E is a safety control system module of Schneider Electric’s Triconex brand and is part of the Tricon Safety Instrument System(SIS).The module is designed for high-reliability industrial safety applications and is widely used in industries with extremely high safety and reliability requirements,such as petroleum,chemical,power,and pharmaceuticals.
Main features
Triple redundant(TMR)architecture
With triple redundant design,each I/O channel contains three independent processing branches,and a voting mechanism is used to ensure that the system can still operate safely in the event of single or multiple point failures.
Complies with international safety standards(such as IEC 61508 SIL 3 and IEC 61511),suitable for safe control of high-risk processes.
Digital input function
Supports 16-point digital input,suitable for monitoring the switch status of field equipment(such as valves,pumps,sensors,etc.).
Input signal types include dry contacts,wet contacts,or NAMUR signals,and are compatible with a variety of field devices.
High reliability and safety
The module has a self-diagnosis function that can monitor hardware failures in real time and trigger alarms.
Support hot swapping,allowing modules to be replaced while the system is running,reducing downtime.
Communicate with the main controller through redundant communication buses(such as TriBus)to ensure the reliability and real-time nature of data transmission.
Environmental adaptability
Wide operating temperature range,suitable for harsh industrial environments.
Strong anti-electromagnetic interference ability,in line with industrial-grade electromagnetic compatibility standards.
Application scenarios
Process safety control:used to monitor and control key process parameters such as pressure,temperature,liquid level,etc.,to ensure that the production process operates within a safe range.
Emergency shutdown system(ESD):When a dangerous situation is detected,the shutdown action is quickly triggered to prevent the accident from expanding.
Fire and gas system(F&G):Monitor fire and combustible gas leaks,and promptly initiate alarms and emergency measures.
Mechanical protection:used for vibration,overspeed and other protection of large rotating equipment(such as compressors and turbines).
Technical parameters
Input type:digital input(DI)
Number of input points:16 points
Signal type:dry contact,wet contact,NAMUR
Working voltage:24VDC(typical)
Communication interface:TriBus(redundant bus)
Ambient temperature:-40°C to+70°C(specific range may vary depending on the model)
Protection level:in line with industrial standards(such as IP20)
Advantages
High security:Triple redundant design significantly reduces the risk of system failure.
Easy to maintain:Hot-swap function and self-diagnosis features reduce maintenance time and cost.
Wide compatibility:supports a variety of input signal types and communication protocols,easy to integrate into existing systems.
Industry recognition:Triconex brand enjoys a high reputation worldwide and is widely used in critical infrastructure and industrial processes.
