Product Details:

TRICONEX 2551 also known as AI2551 is a 16-channel voltage analog input module built with triple modular redundancy (TMR) architecture for Triconex Tricon safety instrumented systems (SIS). This TMR safety I/O module receives voltage signals from field sensors, and converts analog voltage signals into digital data and transmits to the Tricon main controller. The Tricon analog input module supports 0~5VDC and 0~10VDC signal input range, with 12-bit high resolution and independent channel galvanic isolation design to eliminate ground loop noise and electromagnetic interference from field wiring. Continuous built-in channel diagnostics can detect open circuit, short circuit and internal hardware faults, and upload fault alarms to the Tricon engineering workstation in real time. The module supports hot swap operation, maintenance personnel can replace the faulty module online without shutting down the whole safety system. Front panel LED indicators display module health status and each channel signal state for fast on-site troubleshooting. It adopts 2-out-of-3 voting logic to avoid single point of failure and fully meets SIL3 safety integrity level requirements. It can be installed in standard Tricon rack and cooperates with Tricon processor and other I/O modules. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX 2551 analog input module is used for ESD emergency shutdown, fire and gas monitoring and other safety-critical control systems.
