- Certified SIL 3: Third-party certified — simplifies SIL verification and functional safety documentation (FSA)
System Architecture & Signal Flow
Within the Tricon TMR architecture, the 7400209-030 Digital Output module operates across three independent processing legs (Leg A, Leg B, Leg C). Each leg independently evaluates the output command from the Tricon Main Processor Module (MPM). The 2oo3 (two-out-of-three) voting logic ensures that a single-leg disagreement does not cause a spurious output state change. The output signal path is:
Application Logic (TriStation 1131) → MPM (TMR voting) → DO Module 7400209-030 → Field Device (solenoid valve / relay / actuator)
Each output channel is individually fused and monitored. Fault detection is reported back to the MPM and surfaced via TriStation diagnostics and TSAA (Tricon System Access Application) for maintenance visibility. The module interfaces directly with the Tricon I/O bus via the chassis backplane — no external wiring between module and bus is required.
