Description
The TRICONEX AI3351 is a high‑reliability analog input module designed for the Trident triple‑modular redundant safety instrumented system. It acquires 4‑20 mA analog signals from field transmitters such as pressure, temperature and flow sensors. When paired with model 2354 baseplate, it supports HART protocol for smart instrument asset management. Comprehensive channel‑level diagnostics detect open‑circuit, short‑circuit and out‑of‑range field faults. Hot‑swap capability allows online replacement without SIS shutdown. Widely used as spare‑part replacement for legacy Trident safety systems in process industries.
Series
Trident SIS Series by TRICONEX. The Trident platform delivers cost‑effective SIL 3 TMR safety control for medium‑size safety applications. The AI3351 analog input module cooperates with processor modules, other I/O cards and power supplies to build complete safety interlock protection loops. Different mating baseplates (2351, 2354, 2354A) provide standard or HART‑enabled field termination options.
Product Features
- 32 commoned analog input points for 4‑20 mA transmitter signals, operational range 2‑22 mA DC
- Optional HART‑pass‑through function when used with 2354 / 2354A baseplate for smart field device configuration and diagnostics
- Full channel diagnostics: open‑loop, short‑circuit, over‑range and under‑range fault detection
- Hot‑swap supported, online module replacement without interrupting safety‑system operation
- IEC 61508 SIL 3 safety certification for high‑risk process‑safety applications
- 12‑bit ADC resolution, 0.15% full‑scale absolute accuracy for stable measurement performance
- Front‑panel multi‑LED indicators: PASS, FAULT, FIELD ALARM for quick on‑site troubleshooting
- Rugged industrial rack‑mount design, suitable for harsh plant cabinet electromagnetic environments
