System compatibility

TC-303-01-2M0 belongs to ICS TRIPLEX Trusted safety instrumented system and installs in Trusted rack. It serves as dedicated inter-chassis connection interface,realizing high-speed synchronous data communication between main controller rack and expansion I/O rack. Widely deployed in oil & gas,petrochemical and power plants for ESD and fire & gas safety applications.

Function

TC-303-01-2M0 is high integrity TMR chassis expansion interface unit of Trusted SIS. It transmits triple-channel safety data between main rack and expansion rack,keeps I/O signals and controller logic synchronized. It continuously monitors expansion bus status and detects cable break or communication failure.

Installation

Insert TC-303-01-2M0 vertically into dedicated expansion slot of Trusted main rack. Connect the 2m shielded cable between this module and the matching expansion chassis interface card. Verify rack synchronization and bus health via Trusted engineering software.

Interface

‑Gold finger connector for triple redundant backplane bus

‑Expansion port for 2m screened inter-chassis cable

‑Front panel LED indicators for run,bus and fault status

‑Onboard TMR data synchronization and bus diagnostic circuit

Circuit feature

Compact rugged PCB design,built-in surge and ESD protection. TMR triple channel synchronous transmission architecture,fully compliant with SIL3 functional safety hardware specifications.

Feature

TC-303-01-2M0 is spare chassis expansion interface board for ICS TRIPLEX Trusted SIS. Common faults include cable aging,expansion port damage and backplane communication fault. Confirm rack firmware compatibility before replacement.

Diagnostic

When expansion bus disconnection,data synchronization error or onboard hardware failure is detected,the module triggers fault alarm and uploads diagnostic messages to safety workstation.

Built‑in function

TMR safety data transmission between main rack and expansion rack,inter-chassis signal synchronization,expansion bus health monitoring for Trusted SIS rack,used as SIS chassis expansion interface spare replacement.

Product Brief

TC-303-01-2M0 is ICS TRIPLEX SIL3 Trusted chassis expansion interface module with 2m shielded cable,used to expand I/O capacity by connecting main controller rack and expansion chassis in safety instrumented system. Verify system firmware compatibility before ordering. ESD anti-static protection must be followed during handling installation.
