The Triconex 3481 is a high-density, 8-channel Analog Output (AO) module engineered for Tricon v9 through v11 systems. Built on a Triple Modular Redundancy (TMR) framework, this module ensures that single-point failures across any of the three isolated internal branches do not compromise the 4-20 mA safety loop. Essential for final control element modulation in SIL 3 environments where fail-safe operation is mandatory.
Key Specifications
Output Channels: 8 Isolated Points
Signal Range: 4-20 mA (Standard loop-powered instrumentation)
Architecture: Fault-tolerant TMR with redundant circuitry verification
Diagnostics: Comprehensive loop-back checks and field-side power monitoring
Hot-Swappable: Supports online replacement via redundant backplane without process interruption
The industrial world shouldn't run on backorder status. Amikon provides an independent, high-velocity alternative for PLC and DCS hardware procurement. We don't just sell parts; we provide the leverage needed to keep facilities running without manufacturer premiums.
Why Smart MRO Managers Choose Amikon
Zero Phantom Inventory: 1,000,000+ units including hard-to-find I/O cards and CPU modules physically in stock
Price-Maker Edge: Use our "Make an Offer" protocol to align stock with your OPEX budget
Lifecycle Resurrection: Specializing in End-of-Life and obsolete automation components that OEMs have abandoned
Extend Your Legacy System Lifespan
Don't upgrade your entire plant just because one module is obsolete. We provide a strategic lifeline for legacy control systems. Instead of multi-million dollar migrations, we source exact Revision-specific hardware to keep existing DCS or SIS platforms operational for another decade.
