TRICONEX 8310N2 Industrial Control Module

The TRICONEX 8310N2 serves as a critical component for high-availability control systems in demanding industrial environments. This triple modular redundant (TMR) module delivers rock-solid performance for safety instrumented systems (SIS) and process automation applications, particularly in sectors like oil & gas, chemical processing, and power generation where downtime isn’t an option.

This module shines in complex control architectures requiring fault-tolerant capabilities. We’ve seen it deployed in SIL 3-rated systems managing turbine protection circuits and emergency shutdown sequences. For instance, a recent offshore platform installation used 8310N2 modules alongside 3008 and 3703X communication modules to create a redundant safety network. Our typical inventory includes related models like the 4351B, 3624, and 3481S2 for system expansion needs.

The TMR architecture stands out for eliminating single points of failure through its three-channel voting system. Unlike standard PLCs, the 8310N2 maintains operation even with two channel failures. Its seamless integration with TriStation 1131 software allows for online configuration changes without process interruption. The built-in diagnostics system continuously monitors channel health and provides early warnings about potential issues – something that saved a client’s petrochemical plant from a potential trip event last year.
