Product Details:

TRICONEX 3805H is an 8-channel DC coupled analog output module built with triple modular redundancy (TMR) architecture for Triconex Tricon safety instrumented systems (SIS). This TMR safety I/O module receives control commands from the Tricon main processor and generates 4-20mA analog signals to regulate control valves and field process instruments. The Tricon 8-channel 4-20mA analog output module supports 3.8-21mA adjustable signal range, with high precision output and continuous loop monitoring function. It adopts triple redundant signal processing circuits and 2-out-of-3 voting logic to eliminate single point of failure and guarantee stable analog control output. Robust circuit design suppresses electromagnetic interference and ground loop noise in harsh industrial environments. Continuous built-in channel diagnostics can detect open circuit, short circuit and 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 output status for fast on-site inspection and troubleshooting. It can be installed in standard Tricon rack and cooperates with Tricon processor and matching termination panels. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX 3805H analog output module executes process regulation and safety interlock control for ESD emergency shutdown, fire and gas detection and burner management safety interlock systems.
