Product Details:

TRICONEX AO3481 is a high-density TMR analog output module developed for Triconex Tricon safety instrumented systems (SIS). This TMR safety module receives digital control commands from the safety controller, converts digital values into stable 4-20mA analog current signals and optional 0~10VDC voltage signals, and transmits control signals to field valve positioners and regulating actuators. The module adopts triple modular redundant 2-out-of-3 voting architecture, which can maintain normal analog output operation when one redundant channel fails and eliminate single point failure risk. It is equipped with continuous loop readback self-diagnosis for each channel, capable of detecting open circuit, short circuit and signal deviation, 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, analog output termination panels and matched shielded cable assemblies. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX AO3481 analog output module undertakes precision analog control work for ESD emergency shutdown, fire and gas detection and burner management safety interlock systems.
