Applications
The Triconex DI3311 is a vital component in any SIL-rated safety instrumented system (SIS). Engineers use it to gather discrete field inputs and ensure safe operations in hazardous or mission-critical processes. Thanks to its TMR architecture, the module prevents single-point failures from impacting plant safety or availability.
