• Diagnostics: link fault, parity error, framing error, TMR mismatch

• Wide temp: –40°C to +70°C, industrial EMI immunity

4. Technical Parameters

4.1 Communication Ports

• Serial: 4 ports, RS‑232/422/485 (per‑port config)

• Baud rate: 1200–38400 bps

• RS‑485: up to 32 slaves, 1200m max distance

4.2 Safety & Isolation

• Voting: 2‑out‑of‑3 (2oo3)

• Fault coverage: ≥99%

• Isolation: 2500V AC (port–backplane), 1500V AC (port–port)

• Diagnostics: link, parity, framing, TMR mismatch

4.3 Electrical

• Backplane power: 5VDC (logic), 24VDC (aux)

• Power consumption: ≤12W

• Data integrity: 32‑bit CRC, TMR data comparison

4.4 Environmental

• Operating temp: –40°C to +70°C

• Storage temp: –40°C to +85°C

4.5 Mechanical

• Dimensions: Full‑height Trident module (178 × 127 × 63mm)

• Weight: ~0.8kg

5. Function

• SIL3 Communication Bridge: Connects Trident SIS to DCS, HMI, and safety devices via Modbus

• TMR Data Voting: All transmitted/received data is 2oo3 voted for fault tolerance

• Multi‑Port Isolation: 4 serial ports isolated to prevent cross‑fault propagation

• Redundant Links: Supports redundant Modbus networks for high availability

• Fail‑Safe: On module fault, communication stops safely; faults logged in NVRAM

6. LED Indicators (Front Panel)

• PWR (Green): Power OK

• RUN (Green): Normal TMR operation

• FAULT (Red): Module/link/TMR fault

• CH0–CH3 (Yellow): Serial port activity (TX/RX)

7. Installation & Configuration

1. Insert into full‑height Trident I/O slot

2. Connect backplane 5VDC/24VDC power

3. Wire serial/parallel cables to field devices

4. Configure ports (RS‑232/422/485, baud, master/slave) via TriStation 1131

5. Enable Modbus CRC and TMR voting

6. Verify LEDs and communication status

8. Typical Applications

• Trident SIS ↔ DCS (Modbus RTU) safety data exchange

• ESD system ↔ HMI/SCADA for real‑time status & commands

• Safety valve/actuator control via Modbus RTU

• Fire & gas system interface with third‑party detectors

• SIL3 loop data logging & historian integration

9. Maintenance

• Hot swap faulty modules online

• Inspect cables/connectors annually

• Test Modbus communication & TMR voting periodically

• Review fault/SOE logs for link errors

10. Compatibility

• Chassis: Trident full‑height slots

• Software: TriStation 1131

• Compatible processors: Trident Main Processor (MP) modules

• Termination: External RS‑485 termination resistors (as needed)
