TRICONEX 2301 Digital Input Module
TRICONEX 2301 is a digital input module built for Tricon triple modular redundant safety instrumented system. It collects discrete digital signals from field safety switches, limit switches and emergency stop devices for safety logic processing.
This module adopts TMR triple voting fault-tolerant architecture with comprehensive channel self-diagnosis function. It supports hot-swap maintenance without shutting down the whole safety system, widely used as spare replacement for petrochemical, power and chemical safety control cabinet overhaul projects.
