TRICONEX 8111C Communication Module
Product Overview
The TRICONEX 8111C is a redundant communication module designed for TRICONEX’s Tricon Triple Modular Redundancy (TMR) safety systems, serving as a critical link between safety instrumented systems (SIS) and external devices in industrial automation. This module enables seamless data exchange between Tricon controllers, distributed control systems (DCS), HMIs, and SCADA networks, ensuring real-time transmission of safety-critical data in high-risk environments.
As a key component of the Tricon TMR architecture, the TRICONEX 8111C integrates dual redundant communication channels to eliminate single points of failure. It supports Modbus TCP/IP, Ethernet/IP, and TriStation protocols, allowing compatibility with diverse industrial networks. The module fits into Tricon racks alongside processors like the TRICONEX 3008, drawing power via the backplane and communicating with the controller through the TMR bus.
Built to meet stringent safety standards, the TRICONEX 8111C is SIL 3 certified (IEC 61508) and operates in temperatures from -40°C to 70°C with humidity up to 95% (non-condensing). It features 250 V AC isolation between channels and the backplane to resist electrical noise, ensuring reliable communication near large motors or high-voltage equipment. Though a legacy model, the TRICONEX 8111C remains vital for maintaining older Tricon systems, offering backward compatibility with legacy controllers while supporting upgrades to modern networks.

Main features and advantages
Redundant design: The 8111C uses dual redundant communication channels, ensuring uninterrupted data flow if one channel fails. This redundancy is critical for safety systems in oil refineries, where a communication breakdown could delay emergency shutdowns during a leak.
Multi-protocol support: Compatible with Modbus TCP/IP, Ethernet/IP, and TriStation protocols, the 8111C integrates seamlessly with diverse industrial networks—from legacy DCS platforms to modern Ethernet-based HMIs. This flexibility reduces the need for protocol converters, simplifying system architecture.
SIL 3 certification: Certified to IEC 61508 SIL 3, the module guarantees reliable performance in safety-critical applications, such as chemical reactor control, where communication errors could lead to environmental disasters or personnel harm.
Rugged operation: The 8111C works in extreme temperatures (-40°C to 70°C) and high humidity, making it suitable for harsh environments—from arctic pipelines to desert power plants. Its isolation design resists electrical noise, ensuring data accuracy near large motors.
Hot-swappable capability: The module can be replaced while the system runs, allowing maintenance without shutting down critical processes. This feature minimizes downtime in continuous operations like natural gas processing, where unplanned stops are costly.

Installation and maintenance
Pre-installation preparations: Verify the 8111C is compatible with your Tricon rack (e.g., Tricon 4000) and power supply (24 V DC ±10%). Power off the system and disconnect all power sources. Align the module with an empty communication slot in the rack and push until it clicks into the backplane. Connect Ethernet cables to the redundant ports, ensuring cables are routed away from high-voltage lines to reduce noise. Power on the system and check the module’s status LEDs—solid green indicates normal operation.
Maintenance suggestions: Inspect the 8111C quarterly. Wipe dust from the module with a dry cloth to prevent overheating. Test redundant channels monthly using Tricon’s diagnostic software to ensure both are functional. If a channel fails, swap the Ethernet cable first; if the issue persists, replace the 8111C with a spare stored in a dry, cool area (10–30°C). Tighten terminal screws during each inspection to avoid loose connections that could cause data loss.
Application fields
The TRICONEX 8111C is widely used in industries where reliable communication between safety systems and external devices is critical:
- Oil and gas: In offshore platforms, it transmits data from emergency shutdown sensors to onshore SCADA systems via Ethernet/IP. The redundant design ensures operators receive real-time alerts about pipeline pressure drops, enabling timely interventions.
- Chemical processing: In fertilizer plants, the 8111C connects the Tricon SIS to DCS systems, sharing data on reactor temperature and pressure. This allows operators to adjust processes remotely while ensuring the safety system retains control over shutdowns.
- Power generation: In coal-fired plants, it sends turbine vibration data (from analog modules like the 3721) to HMIs, enabling engineers to monitor equipment health without compromising the safety system’s ability to shut down the turbine during overspeed.
- Pharmaceuticals: In sterile manufacturing facilities, the 8111C links the SIS to batch control systems, ensuring temperature and pressure data is shared securely—critical for compliance with FDA regulations on process traceability.
