Product Details:

TRICONEX DI3301 is a high-density 32-point 24VDC TMR digital input module developed for Triconex Trident safety instrumented systems (SIS). This TMR safety module receives discrete on-off signals from field limit switches, pressure switches and contact alarm devices, converting field digital signals into internal data and transmitting the data to the safety controller for safety interlock logic judgment. The module adopts triple modular redundant 2-out-of-3 voting architecture, which can keep normal signal acquisition when one internal redundant channel fails and remove single point failure risk. It supports optical isolation between field side and logic side, effectively suppressing industrial electromagnetic interference. Each channel is equipped with continuous self-diagnosis function, capable of detecting circuit open and short circuit faults and uploading fault alarm information to the controller in real time. The module supports hot swap operation, maintenance personnel can replace the faulty module online without shutting down the whole safety system, minimizing system downtime. It cooperates with Tricon main chassis, digital input termination panels and matched shielded cable assemblies. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX DI3301 digital input module undertakes high-density switch signal collection work for ESD emergency shutdown, fire and gas detection and burner management safety interlock systems.
