The ICS Triplex T8310 is a high-availability expansion processor module designed for critical industrial control systems. Utilizing Honeywell’s patented HIFT (High Integrity Fault Tolerant) TMR architecture, this ruggedized module delivers 99.9999% availability for safety instrumented systems (SIS). The T8310 serves as a processing node in Trusted TMR systems, executing safety logic with <10ms response time for emergency shutdown applications.
Engineered for extreme environments, the T8310 features triple-redundant 32-bit RISC processors with <1μs synchronization skew. Its modular design supports hot-swapping during operation, minimizing downtime in oil/gas and power generation facilities. The module complies with IEC 61508 SIL3 standards for process safety applications.
