AO2481 | Triconex Analog Output Module for Process Safety

Product Description

Overview

The Triconex AO2481 (Part No. 7400209‑010) serves as a high-precision analog output module within the Triconex Trident safety system platform.
It converts digital control signals from the Triconex controller into accurate analog outputs for valves, actuators, and variable speed drives.
Moreover, its Triple Modular Redundancy (TMR) design guarantees fault-tolerant operation, continuous signal integrity, and SIL 3 safety compliance.
This module is widely applied in critical process control and safety environments across industries such as oil & gas, petrochemical, chemical, and power generation.
