TRICON 4000206-520 Analog Input Module

Key Features and Advantages

The TRICON 4000206-520 analog input module delivers SIL 3 certified safety for critical process measurement applications. Featuring 16 triple-redundant input channels, it provides continuous monitoring of analog signals with exceptional accuracy (±0.05% of span) and 16-bit resolution. The module’s universal input design supports multiple signal types including 4-20mA, voltage, thermocouples, and RTDs without requiring external signal conditioners.

Advanced diagnostics: Continuous channel-by-channel monitoring detects open circuits, short circuits, and out-of-range conditions. The 4000206-520 performs automatic drift compensation and provides predictive failure alerts through its comprehensive diagnostic reporting. Its triple-redundant architecture ensures continuous operation even during single-channel failures.

Robust industrial design: With 1500V RMS channel-to-channel isolation, the module eliminates ground loops and protects against electrical noise. The 4000206-520 operates reliably across a wide temperature range (-20°C to +70°C) and withstands high vibration environments. Its hot-swappable design allows replacement without system shutdown in redundant configurations.

Configuration flexibility: TRICON’s TriStation software simplifies setup with drag-and-drop configuration for each channel. The 4000206-520 supports custom scaling, linearization, and filtering for each input. Its high common-mode rejection (>120 dB) ensures accurate measurements in electrically noisy industrial environments.

Safety compliance: Certified for ATEX and IECEx hazardous locations, the 4000206-520 meets stringent safety requirements for oil/gas and chemical processing. The module maintains comprehensive audit trails of all configuration changes and diagnostic events for regulatory compliance.
