Product Overview

The Triconex 3704E is an Analog Input Module designed for use within the Tricon safety instrumented system (SIS) by Triconex, a brand under Schneider Electric (formerly Invensys). This module provides 64 commoned analog input channels to monitor low-level signals (0-5 VDC or 0-10 VDC) from field devices such as pressure, temperature, and flow transmitters. It supports the Triple Modular Redundant (TMR) architecture, ensuring fault-tolerant operation with high-density input capabilities for safety-critical applications in industries like oil & gas, petrochemical, and power generation.
