Communication Module for Tricon v9/v10 Systems | Triconex 3105

Product Description – TRICONEX 3105 Communication Module

The Triconex 3105 communication module supports high-integrity data exchange in demanding safety instrumented environments. It links Tricon v9/v10 controllers with field devices and higher-level systems while maintaining deterministic and fault-tolerant performance. Moreover, its architecture aligns with the strict expectations of SIL3 installations, ensuring dependable behavior throughout continuous operation. The module integrates easily into existing Tricon chassis layouts, and it provides stable performance even in facilities with harsh ambient conditions. In addition, engineers value its predictable response times, which help maintain consistency in safety-critical workflows.

The module delivers redundant communication paths that preserve availability during network issues. For instance, dual Ethernet and serial channels allow process data to move reliably between controllers, HMIs, and DCS platforms. Its support for Modbus TCP/IP, Modbus RTU, and Triconex protocols enables straightforward integration across mixed-vendor environments. Therefore, operators can expand or upgrade control networks without redesigning established infrastructure.
