Description
TRICONEX 3664 – 24VDC Dual Digital Output Safety Module
Product Overview
The 3664 is a high-integrity Dual Digital Output (DDO) safety module manufactured by TRICONEX, designed for Tricon TMR (Triple Modular Redundancy) Safety Instrumented Systems. As a core safety output component, this 32-channel module provides reliable 24VDC discrete control signals for field solenoid valves, trip relays, and safety actuators. It adopts 2-out-of-3 voting logic and comprehensive loop diagnostics to detect latent faults, eliminating silent failures and misoperation risks in critical safety loops. Featuring hot-swappable design and industrial fault tolerance, the TRICONEX 3664 delivers stable, high-safety output performance for continuous and high-risk process industrial scenarios.
