3481 Triconex AO Module | SIL 3 Analog Output for Industrial SIS

Product Description

Overview

The Triconex AO3481 is a high-integrity analog output module designed for precise control of field devices within Triconex Safety Instrumented Systems (SIS).
It provides accurate current or voltage output signals to actuators, valves, and other critical equipment.
Moreover, the module employs Triple Modular Redundancy (TMR) architecture, ensuring continuous operation even if hardware faults occur.
With SIL 3 certification, it is ideal for Emergency Shutdown (ESD), Fire & Gas (F&G), Burner Management Systems (BMS), and High-Integrity Pressure Protection Systems (HIPPS).
