TRICONEX 8111 Product Specification
Product Overview
The TRICONEX 8111 is a high-performance communication interface module designed for TRICONEX’s Triple Modular Redundant (TMR) safety instrumented systems (SIS). It serves as a critical bridge between TMR systems and external industrial networks, enabling secure data exchange between the SIS and host computers, distributed control systems (DCS), and human-machine interfaces (HMIs). This functionality is essential for safety-critical applications where real-time monitoring and control commands must flow seamlessly between systems.
The TRICONEX 8111 supports multiple industrial communication protocols, including Modbus RTU, Modbus TCP/IP, and OPC UA, making it versatile for integrating with diverse automation networks. It operates on a redundant architecture, with dual ports that provide failover capability—if one port fails, the other automatically takes over to maintain communication. As part of TRICONEX’s TMR platform, the TRICONEX 8111 integrates seamlessly with main processor modules like the TRICONEX 3008 and power supply modules such as the TRICONEX 3700A, connecting via the system backplane to ensure low-latency data transfer.
Built to withstand harsh industrial environments, the TRICONEX 8111 operates in temperatures from -40°C to +70°C and handles humidity between 5% and 95% (non-condensing). Its compact design (228 mm × 152 mm × 89 mm) and lightweight structure (1.2 kg) make it easy to install in standard control cabinets. Whether in oil refineries, chemical plants, or nuclear power facilities, the TRICONEX 8111 delivers reliable communication to keep safety systems connected and responsive.

Main Features and Advantages
Redundant communication: The TRICONEX 8111 features dual Ethernet and RS-485 ports. If one port fails, the other takes over instantly. No data loss occurs, and communication continues without interruption. This is critical in oil refineries, where a communication break could delay emergency shutdowns during a leak.
Multi-protocol support: The TRICONEX 8111 works with Modbus, OPC UA, and other common protocols. It can connect to legacy systems (using Modbus RTU) and modern networks (using Modbus TCP/IP) at the same time. This eliminates the need for extra gateways, simplifying system design and reducing costs.
Hot-swappable design: Technicians can replace the TRICONEX 8111 without powering down the TMR system. This minimizes downtime during maintenance—a key benefit in chemical plants where even short shutdowns can disrupt batch processes.
SIL 3 compliance: Built to meet IEC 61508 SIL 3 standards, the TRICONEX 8111 ensures data integrity and reliability in safety-critical applications. It prevents data corruption or delays that could compromise system safety, such as incorrect pressure readings in nuclear power plants.
Compact and rugged: The module’s small size (228 mm × 152 mm × 89 mm) fits in standard 19-inch racks, saving space in crowded control cabinets. It withstands extreme temperatures (-40°C to +70°C) and vibration, making it suitable for outdoor installations like offshore platforms.

Installation and Maintenance
Pre-installation preparations: Before installing the TRICONEX 8111, power off the communication baseplate (e.g., TRICONEX 2201) and verify the power supply is 24 VDC. Check that the baseplate slot is clean and free of debris. Align the module with the slot guides and slide it in until it locks into place. Connect network cables to the Ethernet/RS-485 ports using shielded wiring to reduce electrical noise. Tighten connectors to prevent loose contacts.
Maintenance suggestions: Inspect the TRICONEX 8111 monthly. Check LED indicators—green lights mean ports are active; red lights signal issues (e.g., a disconnected cable). Clean dust from the module’s surface with a dry cloth to maintain airflow. Test redundancy quarterly by disconnecting one port—ensure data flows through the other port without delays. If the module fails to communicate, check cable connections first. If problems persist, replace the module to avoid safety risks.
Application Fields
In oil and gas: The TRICONEX 8111 connects TMR systems on offshore platforms to onshore DCS. It transmits real-time data (e.g., pipeline pressure, valve positions) to HMIs and receives remote shutdown commands. Its redundancy ensures communication stays active during storms, preventing accidents.
In chemical processing: Used in batch reactor SIS, the TRICONEX 8111 links the TMR system to lab systems. It sends reactor temperature and pressure data to quality control software, which then sends adjustment commands back via the module. This ensures chemical mixtures meet specifications and stay within safe limits.
In nuclear power: The TRICONEX 8111 integrates TMR safety systems with grid management platforms. It transmits reactor status data (e.g., coolant levels) to external monitors and receives load adjustment commands. Its SIL 3 compliance ensures data accuracy, critical for preventing nuclear incidents.
In water treatment: Installed in pump station SIS, the module connects to SCADA systems. It sends pump runtime and pressure data to central monitors and receives remote start/stop commands. This allows operators to manage water distribution efficiently while ensuring safety systems (e.g., overflow alarms) work without delay.
