Invensys Triconex Trident safety instrumented system controller

The Triconex Trident Safety Instrumented System package is a SIL3-certified fail-safe, fault-tolerant controller, designed to deliver high reliability and availability for distributed use in refineries, petrochemical, oil and gas plants and other highly hazardous facilities.

Now featuring embedded OPC Universal Architecture communication integration, the system offers  greater connectivity with third-party systems. It complies with IEC 61508:2010 international standards and fulfils the requirements for emergency shutdown, fire and gas, burner management, turbomachinery control, high integrity pressure protection systems (HIPPS) and oil-well RTU system applications that need to be distributed in remote instrumented buildings or located remotely in the production fields. It is suitable for use in environments with operating temperature ranges from -20 to +70°C.

Implementing OPC UA maximises interoperability between systems and streamlines connectivity through open-platform architecture and futureproof design. The new communications interface module also contains an embedded OPC UA server to provide a cohesive, secure and reliable cross-platform framework for real-time data, alarms and events. The new communications interface module also provides enhanced security features by implementing X.509 certificates for additional security protection.

The Trident safety system is scalable from small stand-alone applications (32 I/O points) to large site-wide systems (in excess of 40,000 I/O points), and provides application program execution at millisecond speed for critical control applications.
