Product Introduction

The DS200SLCCG4REG is a quad redundant high-availability fieldbus link controller for GE’s Mark V DS200 series, used in Safety Instrumented Systems (SIS) and mission-critical turbine control. It provides four independent fieldbus interfaces with hardware voting (2 out of 4) for SIL 3 capable communication.

The “4REG” suffix indicates a quad redundant gateway with 2oo4 (two out of four) voting architecture. Four independent 1 GHz processors run identical communication stacks. The board implements hardware voting on all received data: outputs only change when at least two ports agree. If any two ports fail or disagree, the board continues operating using the remaining healthy ports. Use it for the highest availability turbine control applications: nuclear turbine safety systems, pipeline compressor stations, or any installation requiring SIL 3 certified fieldbus communication.

Key Technical Specifications

Key Selling Points & Differentiators

• 2oo4 hardware voting architecture – Four independent processors. Outputs change only when at least two ports agree. Mask faults without single point of failure.
• SIL 3 capable (IEC 61508) – Certified for use in Safety Instrumented Systems. Proof test interval 5 years. Diagnostic coverage >99%.
• 0.25 ms failover – If one or two ports fail, the board continues without interruption. No scan cycle loss.
• 2048 bytes I/O per port – 8192 bytes total I/O per direction.
• True redundancy – Four completely separate fieldbus networks. Connect to four independent switches, four independent cables, four separate power supplies.
• Hardware cross-check – Each processor compares its received data with the other three. Mismatches trigger diagnostics and port isolation.
• SIL 3 certified protocols – Profinet, EtherNet/IP, Modbus TCP all certified for SIL 3 communication.
• External power adapter included – 5 V, 30 A supply (150 W) for the 7.0 A draw.
• QC includes 1000 hour burn-in – 41.6 days continuous, all ports at maximum load, simulated fault injection.
• 10-year warranty – Extended for SIL 3 certified variant.

Frequently Asked Questions (FAQ)

Q: What is the difference between SLCCG4ACC (high performance) and SLCCG4REG (redundant)?

Q: Is the SLCCG4REG certified for SIL 3 today?
A: Yes—TÜV Rheinland certified for SIL 3 per IEC 61508. Certificate included. The board is suitable for use in Safety Instrumented Systems up to SIL 3.

Q: How does the 2oo4 voting work?
A: All four ports receive the same data from four independent fieldbus networks (four separate cables, switches, master devices). Each processor independently decodes and validates its data. The hardware voter compares the four results. Output to Mark V backplane only when at least two results match. Mismatched ports are isolated and reported. The turbine continues operating normally.

Q: What happens if three ports fail?
A: The 2oo4 architecture requires at least two healthy ports. If three ports fail, the voter cannot establish a majority. The board outputs go to failsafe state (configurable: hold last, zero, or preset values). The Mark V CPU receives a diagnostic alarm. For SIL 3 applications, design your fieldbus network so that losing three networks is extremely unlikely (independent power, separate cable trays, diverse routing).

Q: Can I use the REG board without redundant networks?
A: Yes—connect one fieldbus network to all four ports (via four separate cables from one switch). The board will see identical data on all ports. If one processor fails, three remain. However, a single network switch failure still takes down all ports. For true SIL 3 redundancy, use four independent networks.

Q: What is the power requirement?
A: 7.0 A at 5 VDC (35 W). External 5 V, 30 A supply (150 W) included. The board has two auxiliary power inputs for additional redundancy (connect two external supplies). Backplane power is not used—communication only.

Q: What QC tests are specific to the REG revision?
A: Eighteen tests:

1. 2oo4 voting verification: inject faults on 1, 2, 3 ports, verify correct output
2. SIL 3 diagnostic coverage: >99% per IEC 61508
3. Failover time: 0.25 ms measured
4. Port-to-port isolation: 3000 VAC (all 6 pairs)
5. Independent protocol test: 4 different protocols, 168 hours
6. Simultaneous full load: 4 ports, 336 hours (14 days)
7. Fault injection: 1000 simulated faults, zero incorrect outputs
8. Gigabit Ethernet stress: 10 million packets per port
9. Proof test verification: all diagnostic tests pass
10. Security penetration test: IEC 62443-4-2 SL2
11. Temperature: −40°C to +75°C
12. Conformal coating inspection
13. External power redundancy: switch between two supplies
14. Vibration: 5 Grms, 10–500 Hz
15. ESD: ±25 kV contact
16. Radiated immunity: 10 V/m
17. Conducted immunity: 10 V
18. Burn-in: 1000 hours (41.6 days) at +65°C, all ports at max load, continuous fault injection
