TRICON AI2361 | 7400210-020 | Analog Input Safety Module

Technical Specifications

Key Features and Advantages

The AI2361 redefines process safety with quad-redundant signal processing, achieving 99.999% diagnostic coverage for SIL 3 critical applications. Its adaptive noise cancellation technology eliminates EMI interference up to 100V/m while maintaining 24-bit measurement resolution.

Advanced self-diagnostics: Features continuous channel integrity monitoring with predictive drift compensation. The module’s reinforced double isolation barriers exceed ATEX Zone 2 requirements, providing explosion-proof safety in hazardous gas environments.

Smart field integration: Supports HART 7 protocol pass-through for smart transmitters and automatic sensor validation. Hot-swappable design enables field replacement without process interruption, with front-panel OLED displays showing real-time channel diagnostics.

Application Areas

In offshore drilling platforms, the AI2361 monitors critical pressure transmitters and gas concentration analyzers, ensuring IEC 61511 compliance for emergency shutdown systems. Its 10ms scan rate prevents overpressure incidents in wellhead control applications.

Nuclear power plants utilize this module for reactor coolant temperature monitoring, leveraging its radiation-hardened components and <0.5μV noise floor. The extended temperature range supports operation in passive cooling scenarios during station blackouts.

Chemical processing facilities benefit from ATEX certification for corrosive environment applications, while the high channel density reduces cabinet space in API 670-compliant machinery protection systems.
