Description
ICS Triplex T8310C
Technical Specifications & Performance Parameters:
- Power Supply: 20 ‑ 32 V DC, backplane power input, nominal 24 V DC
- Operating Temperature: ‑40 °C ~ +70 °C
- Storage Temperature: ‑40 °C ~ +85 °C
- Power Dissipation: 38 W maximum
- Safety Certification: TÜV IEC 61508 SIL 3
- Communication Interface: High‑speed redundant inter‑rack bus interface
- Weight: 1.08 kg
- Form Factor: Standard 3U rack plug‑in module
Functional Features:
- TMR triple‑channel redundant architecture, finish local I/O signal acquisition and voting processing inside expander rack
- Independent comprehensive diagnosis for every I/O channel in expander rack
- Hot‑swap support; online replacement without shutting down expander rack I/O function
- Redundant inter‑rack communication link, automatic switchover when one link fails
- Front‑panel LED indicators display module running state, communication status and fault alarms
- Transmit expander rack fault diagnostic information to main processor for unified alarm management
- Realize signal pre‑processing to reduce data transmission load of inter‑rack bus
- Support multiple expander racks cascading to expand overall system I/O capacity
Working Principle: Three internal redundant channels collect data from expander rack I/O modules simultaneously, complete local hardware voting for input signals. Valid processed data transmits to main rack processor through redundant inter‑rack bus. Fault diagnosis of each I/O module inside expander rack runs continuously. Fault messages are uploaded to main rack. When inter‑rack communication single link fails, backup link takes over transmission task immediately.
Material Composition & Structural Characteristics:
- Housing: Die‑cast aluminum alloy anti‑interference shell
- Circuit board: Industrial multi‑layer FR‑4 printed circuit board
- Connector: Gold‑plated high‑density anti‑vibration backplane connector
- Front panel: Flame‑retardant engineering plastic with LED indicator array, IP20 protection grade
- Card‑type plug‑in structure for expander rack slot installation
Installation Requirements:
- Install into dedicated expander processor slot of Trusted expander rack
- Expander rack must configure redundant 24 V DC power supply
- Inter‑rack communication cable adopts special shielded industrial cable, strictly follow wiring specification
- Control cabinet maintains good ventilation heat dissipation condition
- Cabinet protective ground connection must be reliable, ground resistance ≤4 Ω
- Avoid installation location with severe vibration, corrosive gas and salt‑fog environment
Application Scenarios:
- Distributed I/O expansion for large petrochemical ESD safety system
- Remote field I/O rack for offshore oil‑gas platform safety control
- Geographically scattered safety interlock points for chemical plants
- Fire‑gas monitoring system with large‑quantity distributed field sensors
- Power plant auxiliary workshop safety instrumented system expansion
Usage Notes:
- Perform hot‑swap operation only under system normal health condition
- Do not disassemble module housing; internal components cannot be repaired on‑site
- Check inter‑rack communication cable tightness regularly
- After replacement, verify expander rack I/O signal acquisition and communication status
- Do not operate outside rated temperature range
- Avoid mechanical impact during transportation and installation
