Product Details:

TRICONEX 3700 is a 16-channel TMR analog input module built with triple modular redundancy (TMR) architecture for Triconex Tricon safety instrumented systems (SIS). This TMR safety I/O module collects 0-5VDC voltage signals from field pressure, temperature and level transmitters, converting analog sensor signals into digital data for the Tricon main controller. The Tricon analog input module supports 6% over-range measurement capability and 12-bit signal resolution. Each channel is equipped with independent signal processing circuits and adopts reliable anti-interference design to reduce ground loop noise and electromagnetic interference from field wiring. Continuous built-in channel diagnostics can detect open circuit, short circuit, signal overrange and internal 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 signal state for fast on-site inspection and troubleshooting. It adopts 2-out-of-3 voting logic to eliminate single point of failure and fully meets SIL3 safety integrity level requirements. It can be installed in standard Tricon rack and cooperates with Tricon processor and other I/O modules. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX 3700 analog input module is used for ESD emergency shutdown, fire and gas monitoring and other safety-critical control systems.
