Product Details:

TRICONEX 3401 also known as DO3401 is a 16-channel TMR digital output module developed for Triconex Trident safety instrumented system (SIS). This TMR safety I/O module adopts triple modular redundancy architecture and 2-out-of-3 voting logic to avoid single point of failure, converting digital safety commands from the Trident main controller into 24VDC discrete signals to drive solenoid valves, safety relays and field actuators. The Trident digital output module provides built-in circuit diagnostics for each channel, continuously detecting open circuit, short circuit and hardware faults, and uploading fault alarms to the TriStation engineering workstation in real time. The module supports hot swap operation, maintenance personnel can replace the faulty module online without shutting down the whole safety system. Front panel LED indicators display module health status and each channel output state for fast on-site troubleshooting. It complies with SIL3 safety integrity level requirements and can be installed in standard Trident rack, working together with Trident processor and other I/O modules. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX 3401 digital output module executes safety interlock actions for ESD emergency shutdown, fire and gas protection and burner management systems.
