Product Details:

TRICONEX 3725 is a high-density 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 analog signals from field pressure, temperature, flow and level transmitters, converting analog sensor signals into digital data and transmitting to the Tricon main controller. The Tricon analog input module supports 4-20mA current signal input, with 2~22mA extended range for transmitter fault detection. It supports programmable 12-bit or 14-bit signal resolution and delivers high measurement accuracy within the rated operating temperature range. The module adopts robust anti-interference circuit design to suppress electromagnetic interference and ground loop noise from long field instrument wiring. Continuous built-in channel diagnostics can detect open circuit, short circuit, signal underrange, 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 3725 analog input module is used for ESD emergency shutdown, fire and gas monitoring and other safety-critical control systems.
