System compatibility
T9191 belongs to ICS TRIPLEX Trusted SIS safety instrumented system and installs in main processor rack. It acts as dedicated communication co-processor,offloading heavy communication workload from T9100 series main processor. It handles data exchange between Trusted SIS,HMI,DCS and third-party field devices. Widely deployed in oil & gas,petrochemical and power generation plants for ESD,turbine protection and fire & gas safety applications.
Function
T9191 serves as high integrity TMR communication interface unit of Trusted SIS. It executes TMR 2oo3 hardware voting for all transmitted safety data,implements time synchronization and protocol conversion. It reduces main CPU load and ensures stable safety data transmission. It supports hot swap replacement without shutting down the safety rack.
Installation
Insert T9191 vertically into dedicated slot of Trusted main rack. Connect redundant network and serial cables. Verify communication link status via Trusted Workbench engineering software.
Interface
‑Gold finger connector for triple redundant backplane bus
‑Redundant Ethernet ports and serial communication terminals
‑IRIG-B time sync input port
‑Front panel LED indicators for run,alarm and communication fault
‑Onboard TMR communication processing and diagnostic circuit
Circuit feature
Conformal coated multi-layer PCB design,built-in surge and overvoltage protection circuit. Triple slice independent data processing and hardware voting design,fully compliant with SIL3 functional safety hardware specifications.
Feature
T9191 is spare communication interface board for ICS TRIPLEX Trusted SIS. Common faults include Ethernet port failure,backplane communication error and signal attenuation. Confirm rack firmware version before replacement.
Diagnostic
When communication loss,channel mismatch or onboard hardware failure is detected,the module triggers fault alarm and uploads diagnostic messages to safety workstation.
Built‑in function
Safety data communication processing,protocol conversion,IRIG-B time synchronization and TMR signal voting for Trusted TMR SIS rack,used as SIS communication interface spare replacement.
Product Brief
T9191 is ICS TRIPLEX Trusted SIL3 TMR communication interface module,hot swappable for Trusted main rack,used to offload communication tasks for main safety processor. Verify system firmware compatibility before ordering. ESD anti-static protection must be followed during handling installation.
