System compatibility
T8480C belongs to ICS TRIPLEX Trusted SIS safety instrumented system and installs inside T8300 or T8314 expander rack. It receives triplicated safety trip commands from expander processor and outputs 24VDC discrete signals to drive field safety relays,solenoid valves and shutdown actuators. The conformal coated PCB protects internal circuits from moisture and chemical vapour,suited for offshore and heavy industrial safety applications. Widely deployed in oil & gas,petrochemical and chemical plants for ESD emergency shutdown and fire & gas safety protection.
Function
T8480C serves as high integrity 40-channel 24V digital output unit of Trusted TMR SIS. It executes TMR 2oo3 hardware voting logic to output safety trip signals for final safety elements. It supports 1ms high precision SOE sequence of events recording for incident trace analysis. Each channel continuously monitors open circuit,short circuit and overload faults. It supports hot swap replacement without shutting down the safety expansion rack.
Installation
Insert T8480C vertically into dedicated I/O slot of T8300/T8314 expander chassis. Connect field solenoid and relay wiring to terminal assembly. Verify output status and fault alarms via Trusted Workbench engineering software.
Interface
‑Gold finger connector for triple redundant backplane bus
‑Field termination interface for 40-channel 24VDC digital output wiring
‑Front panel LED indicators for per-channel run,alarm and fault status
‑Onboard TMR output control,overcurrent protection and channel diagnostic circuit
Circuit feature
Conformal coated multi-layer PCB design,built-in surge and overvoltage protection circuit. Triple slice independent output control and hardware voting design,fully compliant with SIL3 functional safety hardware specifications.
Feature
T8480C is spare conformal coated 40-channel 24VDC digital output board for ICS TRIPLEX Trusted SIS. Common faults include output channel burnout,field wiring short circuit and backplane contact fault. Confirm field actuator load and chassis compatibility before replacement.
Diagnostic
When channel open circuit,short circuit,overload or onboard hardware failure is detected,the module triggers fault alarm and uploads diagnostic messages and SOE event logs to safety workstation.

Built‑in function
Safety discrete 24VDC signal output,per-channel overcurrent & wiring fault monitoring and TMR signal voting for Trusted TMR expansion rack,used as SIS digital output spare replacement.
Product Brief
T8480C is ICS TRIPLEX Trusted SIL3 TMR conformal coated 40-channel 24VDC digital output module,hot swappable for T8300/T8314 expander chassis,used for ESD solenoid valve and safety relay driving in harsh industrial environments. Verify system firmware compatibility before ordering. ESD anti-static protection must be followed during handling installation.
