2. Hardware Specifications
-
Electrical Specifications
‑Backplane power supply:20‑32VDC powered by chassis backplane; typical power consumption approx.40W
‑Architecture:Three independent 32‑bit RISC processors, TMR triple‑modular redundancy with HIFT hardware fault tolerance; 2MB RAM, 8MB Flash ROM
‑High‑speed link rate: 250 Mbps, communication via TC‑301 hot‑link cable and T8312 adapter unitNEX Instru….
-
Front‑panel & Indicators
‑Multi‑group front‑panel LEDs: Module OK, Fault, Link status, Voting status;
‑Hot‑swap handle for on‑line replacement without interrupting other expander chassis.
-
Environmental Conditions
‑Operating temperature:0℃ ~ +60℃; Storage temperature:‑25℃ ~ +85℃
‑Relative humidity:5‑95% non‑condensing; IP20 (inside cabinet); EMC anti‑interference, shock‑vibration resistant for industrial environment.
3. Key Functions
- Local TMR processing for expander chassis: All I/O modules inside expander chassis complete local three‑channel data acquisition, voting and fault diagnostics by T8310, reducing computing load of main‑chassis T8110C / T8111C main processors.
- High‑speed safe bridging to main chassis: Interconnect main‑chassis T8161B expander‑interface via T8312 adapter and TC‑301 cable. Deterministic low‑latency safe data transmission is realized. I/O points are transparent to main CPU without program modification.
- Fault tolerance and fault containment: HIFT hardware fault‑tolerant technology. Single‑channel faults are isolated automatically. Supports automatic / manual repair strategy and hot‑standby module. Faults from expander side cannot propagate to main‑chassis core control areaNEX Instru….
- Comprehensive self‑diagnosis: Real‑time monitoring of three‑channel status, backplane, high‑speed link and I/O subsystem. Timestamped fault messages uploaded to system software; front‑panel LEDs support fast on‑site troubleshooting.
- Hot‑swap maintenance: Faulty module can be replaced online without shutdown of whole SIS system.
4. Typical Applications
‑Large‑scale SIS projects with distributed cabinet layout for petrochemical & chemical ESD emergency shutdown and F&G fire‑gas systems
‑Safety instrumented systems on offshore oil‑gas platforms and power plants with multiple remote I/O expander cabinets
5. Important Notes
- T8310 is only for expander chassis, cannot be fitted into T8100 main chassis, and cannot replace T8110C / T8111C main processor.
- Matching accessories: TC‑301 hot‑link cable, T8312 expander‑interface adapter unit; main chassis shall be equipped with T8161B expander‑interface module.
- Firmware version must strictly match main‑chassis T8110C/T8111C and T8161B. Mismatched firmware will cause expander‑chassis communication failure. Verify firmware build‑number for spare‑part replacement.
- T8310 must be installed on left‑hand processor slot of expander chassis, otherwise expander‑chassis I/O modules cannot work normally.
- Only compatible with Trusted T8000‑series expander chassis, not applicable for other generic PLC racks.
