Product Description
Hardware Architecture & Signal Arbitration
The AO3481 operates as a 16-point sourcing module (4-20 mA) specifically designed for the Tricon Triple Modular Redundancy (TMR) platform. Its core logic utilizes hardware-level 2-out-of-3 (2oo3) voting to ensure that any single-component failure—whether a DAC drift or microprocessor leg mismatch—is out-voted at the terminal stage. This provides a deterministic command path that prevents uncommanded actuator movement, delivering the reliability necessary for SIL3-rated governors and modulating control valves.
Supervisory Diagnostics & Loop Integrity
Signal verification is maintained through continuous, real-time current-to-voltage read-back. The module monitors actual loop current and cross-references it against the internal setpoint commanded by the Main Processors (MPs). This diagnostic detects high-impedance faults, open-loop field wiring, and "stuck-at" conditions without external hardware. Galvanic isolation (1500V) is standard across all 16 channels, shielding the TMR backplane from field-side EMI, grounding transients, and 24V bus fluctuations.
Operations & Maintenance with Thermal Deployment Specifications
Uptime is prioritized via a "Hot-Spare" slotting strategy, enabling module replacement under full process load without loop interruption. The hardware is thermally hardened for -20°C to 60°C operational envelopes, specifically designed for unconditioned Remote Instrument Buildings (RIB). Front-panel LEDs provide direct diagnostic mapping to individual channels, facilitating lower Mean Time to Repair (MTTR) by allowing technicians to differentiate between internal hardware faults and external field-wiring discrepancies without software debuggers.
Forget the 6-month lead times. We operate on "Factory Time"—where every minute counts.
