TRICONEX 8111
TRICONEX 8111 is an industrial control module based on triple modular redundancy (TMR) architecture under Invensys, designed for high safety and high availability scenarios, widely used in fields such as petrochemicals, power, rail transit, and nuclear industry. The following is a comprehensive overview of its core functions and technical features:
1. Core functions and architecture
Triple Redundancy (TMR) Design
Adopting triple independent channel parallel operation, each channel executes the same control program, and real-time data consistency is verified through hardware voting mechanism to ensure that single point faults do not affect system operation, in compliance with IEC 61508 SIL 3 and IEC 61511 safety standards.
Hot swappable capability
Support online replacement of faulty modules without the need for downtime maintenance, ensuring process continuity.
High density I/O expansion
A single module can be expanded to 128 channels, compatible with digital, analog, and pulse input/output, meeting complex control requirements.
2. Technical parameters
Parameter specifications
Input voltage 24 V DC or 48 V DC
Output voltage 0-10V DC
Working temperature -40 ° C to 85 ° C
Communication protocols Modbus TCP/IP, Hiway, UCN
NEMA 4X aluminum sealed enclosure, suitable for harsh industrial environments
Dimensions: 100mm x 80mm x 30mm
Self diagnostic function monitors hardware status in real-time, automatically isolates and records faults
3. Application scenarios
Safety interlock system (ESD): used for emergency shutdown control, such as in petrochemical plants and natural gas processing stations.
Fire and Gas Monitoring (F&G): Real time detection of combustible gases and fire signals, triggering safety responses.
Turbine control: speed, vibration monitoring and protection of steam/gas turbines.
Compressor anti surge: prevents equipment damage through pressure and flow control.
Nuclear industry safety system: 1E safety level, ensuring the reliability of nuclear reactor control.
4. Special characteristics
Network protection: Built in deep network protection to prevent data transmission interruption or damage.
Intelligent diagnosis: supports fault location and alarm, reducing downtime.
Multi protocol compatibility: Can be integrated with mainstream systems such as Siemens, Honeywell, ABB, etc.
5. Typical configuration examples
Expansion chassis (8111N): Supports hot swappable module expansion and integrates communication and power redundancy.
Digital Input Module (T8111C): 40 channel isolated input, suitable for Safety Instrumented Systems (SIS).
Analog output module: high-precision pulse control, used for motor speed regulation or valve adjustment.
