Triconex 3411 24VDC Analog Input Module for ESD & HIPPS

Product Description

Overview

The Triconex 3411 is a high-integrity analog input module designed for safety-critical applications within Triconex Safety Instrumented Systems (SIS).
It acquires analog signals from field devices such as pressure transmitters, temperature sensors, and flowmeters, converting them into precise digital values for Tricon controllers.
Moreover, the module utilizes Triple Modular Redundancy (TMR) architecture, ensuring continuous operation even in the event of hardware faults.
Its SIL 3 certification makes it ideal for emergency shutdown, fire & gas, and high-integrity pressure protection applications.
