제품 설명
The Triconex DO3401 is a high-density Digital Output (DO) module engineered for integration into Triple Modular Redundant (TMR) safety instrumented systems. Designed to interface directly with final control elements—such as solenoids, relays, and motor starters—the DO3401 executes discrete command logic within a fault-tolerant framework. Physically, the module is housed in a compact 1.4 kg form factor (4.5 × 18.8 × 20.8 cm), making it a standard choice for high-availability ESD (Emergency Shutdown) and F&G (Fire & Gas) racks requiring robust signal density.
Electrical integrity is maintained through a specialized dual-layer isolation architecture that decouples the field-side circuits from the safety-critical logic. It provides Functional-to-Protective-Earth (PE) isolation of ≥ 500 V DC and a higher-tier Functional-to-Logic isolation of ≥ 800 V DC, effectively shielding the TMR backplane from ground loops, EMI transients, and common-mode noise. This galvanic segregation is a fundamental requirement for maintaining the SIL-3 integrity of the overall control loop when operating in high-voltage or electrically "noisy" industrial environments.
Advanced diagnostics are a cornerstone of the DO3401's operational profile, utilizing high-speed glitch testing to verify output switchability without disrupting the process. The diagnostic window is highly deterministic, with a typical duration of 500 µs and a maximum ceiling of <2 ms, ensuring that supervisory tests remain invisible to field devices. Beyond switch-testing, the module triggers immediate Field Alarms for critical failure modes, including loss of field power and output points shorted in either the "On" or "Off" state. This level of granular telemetry ensures rapid fault isolation and minimizes the Mean Time To Repair (MTTR) in mission-critical safety loops.
