• Scan Time: ≤10ms (typical safety logic)

• I/O Capacity: Up to 8,000 points (mixed AI/DI/AO/DO)

• TriBus: 25Mbps high‑speed backplane, 32‑bit CRC protected

• Serial Comm: Isolated RS‑232 (500VDC isolation) for diagnostics

• SOE: 1ms resolution (basic logging)

• Hot‑Swappable: Online replacement; redundant CPU support

4. Technical Parameters

4.1 Processing

• CPU: 3× Motorola MPC860, 32‑bit, 50MHz

• Memory: 16MB DRAM / 32KB SRAM (battery) / 6MB Flash

• Scan Time: ≤10ms

• I/O Capacity: Up to 8,000 points

• Voting: 2oo3 fault‑tolerant, mid‑value selection

4.2 Communication Interfaces

• TriBus: 25Mbps backplane, 32‑bit CRC, fully isolated

• Serial: 1× RS‑232 (25‑pin), 500VDC isolation

• Protocol Support: TriBus, Modbus RTU (serial)

• Ethernet: None (no onboard Ethernet; requires comm module)

4.3 Redundancy & Safety

• Diagnostic Coverage: >99%

• System Availability: 99.999%

• Safety Certification: SIL3 (IEC 61508), TÜV, FM, CSA

4.4 Environmental

• Operating Temperature: 0°C to +60°C

• Storage Temperature: −40°C to +85°C

• Humidity: 5%–95% non‑condensing

• Vibration: 5–200Hz, 1g

• Protection: IP20

4.5 Power & Physical

• Backplane Power: 5VDC

• Power Consumption: ≤15W

• Dimensions: Legacy Tricon full‑size (228×160×75mm)

• Weight: ~1.5kg

5. Function Overview

• System Control: Executes safety logic, manages legacy Tricon I/O, coordinates TMR voting

• TriBus Gateway: High‑speed I/O communication (no Ethernet)

• Data Logging: Basic 1ms SOE (limited storage)

• Redundancy Management: Seamless TMR failover; no single point of failure

• Online Maintenance: Logic download, hot‑swap, runtime diagnostics

6. LED Indicators

• PASS (Green): Self‑diagnostics OK

• ACTIVE (Green): Program executing

• FAULT (Red): CPU/memory/comm fault or voting mismatch

• MAINT1/MAINT2 (Yellow): Maintenance alerts

7. Installation & Configuration

1. Insert 3008 into legacy Tricon full‑size CPU slot

2. Connect RS‑232 to diagnostic terminal

3. Use TriStation 1131 (v3.x) to program logic, configure TriBus

4. Verify: PASS+ACTIVE green; no FAULT red

8. Typical Applications

• Legacy ESD/BMS: Oil/gas, chemical, power (old plants)

• Small‑to‑Medium SIS: Up to 8,000 I/O points

• Retrofit Projects: Replaced by 3005 (Trident) or 3006 (next‑gen)

9. Maintenance & Support

• EoS Status: No official support; third‑party repair only

• Hot‑swap 3008 with spare (legacy stock)

• Review fault logs via TriStation v3.x

• Upgrade path: Migrate to 3005 (Trident) or 3006 (3008/3009 SIS)

10. Compatibility

• Compatible Systems: Legacy Tricon SIS (not Trident/3006)

• Configuration Software: TriStation 1131 (v3.x only)

• Matching I/O: Legacy Tricon series (e.g., 2700/2750)

• Model: 3008
