Product Overview

The 8310 (Model: 8310) is a high-reliability 175W power module designed for the Invensys Triconex Triple Modular Redundancy (TMR) safety system. This module is engineered to provide a stable and efficient DC power source to the internal backplane bus, supporting the operation of processors, communication modules, and I/O interfaces. Built for mission-critical industrial safety applications, the 8310 (Part Number: 8310) ensures deterministic system performance across main, expansion, and Remote Expansion Module (RXM) chassis.

With its dual AC/DC input capability, the 8310 offers exceptional installation flexibility. It is designed to withstand the rigors of extreme industrial environments, incorporating advanced protective features such as integrated time-delay fusing and overvoltage regulation. In a typical Triconex configuration, these modules are used in redundant pairs to maintain "Always-On" safety logic execution, preventing unplanned shutdowns in high-risk process environments.
