Product Details:

TRICONEX 3481 AO3481 is a high-reliability TMR analog output module developed for Triconex safety instrumented systems (SIS). This TMR safety module receives safety control commands from the Tricon safety controller, converting digital logic data into stable 4-20mA or 0-10V analog output signals, and sending analog signals to control valve positioners, actuators and regulating field equipment. The module adopts triple modular redundant 2-out-of-3 voting architecture, which can maintain stable analog output control when one internal redundant channel fails and eliminate single point failure risk for critical safety control loops. It has 8 independent isolated channels with 16-bit high resolution, and the signal output accuracy can reach ±0.1% full scale. Each channel supports continuous built-in self-diagnosis function, capable of detecting circuit open circuit, short circuit, signal loss and abnormal output state, and uploading fault alarm information to the safety controller in real time. The module supports hot swap operation, maintenance personnel can replace the faulty module online without shutting down the whole safety system, reducing system downtime. It cooperates with Tricon main chassis, FTA field termination assemblies and matched shielded cable assemblies. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX 3481 AO3481 analog output module undertakes precise analog control work for ESD emergency shutdown, fire and gas detection and burner management safety interlock systems.
