Description
PRODUCT OVERVIEW
Triconex DO3401 is a high-density digital output module specially matched for Tricon triple modular redundancy (TMR) safety instrument system (SIS), which converts safety logic commands issued by the main controller into on-site switching signals to drive solenoid valves, safety relays, emergency shutdown actuators and field indicator lights.Adopting native TMR three-channel independent redundant operation architecture, each output channel is equipped with isolated drive circuit, real-time loopback detection and hardware self-check function, meeting SIL3 highest safety integrity level certification standard. The module adopts hot-swappable rack plug-in design, which can be replaced online without shutting down the whole SIS system, effectively reducing equipment maintenance downtime.
Built-in channel independent overcurrent, short-circuit and reverse voltage protection circuit, with front panel LED indicator for single-channel status, module fault and power supply alarm. Cooperate with supporting 2401 series terminal base to complete field wiring docking, widely used in petrochemical ESD emergency shutdown systems, natural gas pipeline safety interlock, thermal power boiler protection, refinery fire & gas safety control and other high-risk process safety control occasions.
