Product Details:

TRICONEX 2755 also known as AO2755 is an 8-channel TMR analog output module built with triple modular redundancy (TMR) architecture for Triconex Tricon safety instrumented systems (SIS). This TMR safety I/O module receives digital safety control commands from the Tricon main controller and converts digital signals into standard 4-20mA analog current signals to regulate field modulating valves and control actuators. The Tricon analog output module supports 2~22mA extended signal range, and provides accurate analog variable output for safety control loops. It adopts channel galvanic isolation design to suppress 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 alarm messages 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 PASS, FAULT and each channel signal status for fast on-site inspection and troubleshooting. It adopts 2-out-of-3 voting logic to eliminate 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 2755 analog output module is used for ESD emergency shutdown, fire and gas protection and burner management safety interlock control systems.
