System compatibility

This input hardware belongs to ICS TRIPLEX Trusted SIS safety instrumented system and is installed inside Trusted rack cabinet. It collects analog signals from field pressure, temperature and flow transmitters. It transmits validated analog data to TMR processor module for safety interlock logic calculation. It communicates with system engineering workstation,widely used in oil & gas,petrochemical and chemical plants for ESD emergency shutdown and fire & gas safety protection.

Function

T3120 serves as the safety analog signal acquisition unit of Trusted TMR SIS. It detects analog process values from field safety transmitters,filters and validates input signals. It continuously runs per-channel self-diagnosis to detect open circuit,short circuit and input circuit hardware failure in real time.

Installation

Insert the module vertically into dedicated I/O slot of Trusted SIS rack. Complete field transmitter wiring and backplane bus connection,verify channel input status and fault diagnosis via Trusted Workbench engineering software.

Interface

‑Gold finger connector for triple redundant backplane bus communication

‑Field analog input terminal block for transmitter connection

‑Onboard TMR voting and signal conditioning circuit

‑LED indicators for channel running,alarm and fault prompt

Circuit feature

Conformal coated multi-layer PCB design,built-in surge and overvoltage protection circuit. Triple channel hardware voting design,fully compliant with SIL3 functional safety hardware specifications.

Feature

T3120 is a spare analog input board for ICS TRIPLEX Trusted SIS system. Common faults include input detection circuit damage,signal acquisition chip failure and field wiring fault. Confirm rack slot definition and firmware compatibility before replacement.

Diagnostic

When channel open circuit,short circuit or hardware breakdown is detected,the module will trigger fault alarm and upload diagnostic messages to safety workstation.

Built‑in function

Field analog safety signal acquisition and channel hardware self-diagnosis for Trusted TMR safety rack,used as SIS analog input spare replacement.

Product Brief

T3120 is ICS TRIPLEX Trusted SIL3 analog input module,supporting TMR triple modular redundant architecture. Verify rack compatibility before ordering. ESD anti-static protection must be followed during handling installation.
