TRICONEX

Functions

1. Designed for Tricon V9/V10/V11 Safety Instrumented System (SIS). Adopts TMR (Triple Modular Redundancy) technology with 2-out-of-3 voting logic to eliminate single point of failure, certified for SIL3 per IEC61508.
2. 8 configurable analog output channels. Supports standard signal ranges: 4–20mA and 0–10VDC for continuous modulating control.
3. Comprehensive channel diagnostics for open circuit, short circuit and module faults. Supports hot-swap replacement; module can be changed online without system shutdown.
4. Converts digital signals from safety controller into industry-standard analog signals to operate field devices. Three independent internal circuits perform parallel calculation and voting to guarantee safe output under fault conditions.
5. Configurable via TriStation software and requires dedicated termination baseplate.

Applications

1. Widely deployed in Safety Instrumented Systems (SIS), Emergency Shutdown Systems (ESD) and anti-surge control systems for high-risk industries: oil & gas, petrochemical, power plant, LNG, coal chemical industry.
2. Provides control signals to pneumatic control valves, electric actuators and valve positioners for continuous process regulation of pressure, temperature and flow loops.
3. Mainly supplied as spare parts for existing Tricon installed base. Trident series modules are recommended for new projects; 3481 is primarily used for plant revamp and replacement.
4. Typical applications: reactor control, compressor anti-surge control, pipeline pressure regulation, flare system safety control and other critical process safety loops.
