Product Description
Triconex 7400166 External Termination Panel
Product Overview
- The Triconex 7400166 is an External Termination Panel (ETP) designed for the Triconex Safety Instrumented System (SIS), part of Schneider Electric’s EcoStruxure Tricon platform. It serves as an interface between Triconex digital output modules (e.g., 2652-1) and field devices, providing secure and reliable connections for output signals. Used in safety-critical applications in industries like oil and gas, chemical, and power generation, the 7400166 supports the Triple Modular Redundant (TMR) architecture, ensuring compliance with Safety Integrity Level 3 (SIL3) requirements.
