• Key Specs: 32 high-brightness LEDs | SIL 2 | Safety inputs | Safety relay outputs | >90% diagnostics
• Condition: New Original.

Product Introduction

The DS200STBAG1ABB is a high-reliability safety status annunciator board for GE’s Mark V DS200 series, used in Safety Instrumented Systems (SIS) for turbine control. It provides 32 high-brightness LED indicators with SIL 2 certification for safety-critical alarm annunciation.

The “ABB” suffix represents the high-reliability safety variant. SIL 2 certified per IEC 61508. Features: 32 high-brightness LEDs (red/yellow/green), 16 safety-rated discrete inputs, 8 safety relay outputs, diagnostic coverage >90%, and automatic self-test. Use it for safety annunciation in SIL 2 applications: emergency shutdown indication, fire and gas alarms, and critical process alarms where annunciator failure cannot be tolerated.

Key Technical Specifications

Key Selling Points & Differentiators

• SIL 2 certified annunciator – TÜV certified for safety-critical alarm annunciation. Use in SIL 2 safety functions.
• High-brightness LEDs (10,000 mcd) – Visible in bright control rooms and direct sunlight.
• Safety-rated inputs (SIL 2) – 16 discrete inputs with open-wire and short-circuit detection.
• Safety relay outputs (SIL 2) – 8 outputs with welded contact detection.
• Diagnostic coverage >90% – Automatic self-test daily. Reports failures to safety PLC.
• Automatic LED test – Daily test verifies all 32 LEDs functional.
• Proof test interval 1 year – Automatic self-test reduces manual proof test burden.
• QC includes SIL 2 validation – TÜV-certified test procedures.
• 5-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between STBAG1A (standard) and STBAG1ABB (SIL 2)?

Q: When do I need a SIL 2 annunciator?
A: When the annunciator is part of a safety function. Example: Emergency shutdown panel must indicate “valve closed” status. If the annunciator fails to show the status, operator may take incorrect action. SIL 2 annunciator detects its own failures.

Q: How does the board test its LEDs?
A: Every 24 hours, the board briefly lights each LED (20 ms) in sequence. If an LED fails to light, the board sets a diagnostic fault and reports via relay output. The LED test is fast enough that operator may not notice.

Q: Can I use the ABB board in a non-safety application?
A: Yes—it functions as a standard annunciator. The safety features provide additional reliability.

Q: What is the input diagnostic coverage?
A: >90% per IEC 61508. Detects: open wire (sensor disconnected), short to ground, short to 24 V, stuck input. Reports fault via relay output.

Q: What QC tests are specific to the ABB revision?
A: Ten tests:

1. LED intensity: all 32 LEDs at spec (10,000/8,000 mcd)
2. Input diagnostics: open-wire, short-circuit detection
3. Output diagnostics: welded contact detection
4. Automatic self-test: daily schedule verified
5. Diagnostic coverage: >90% via fault injection
6. PFDavg calculation: <1.0 × 10⁻²
7. Isolation: 2500 VAC
8. Temperature: −40°C to +70°C
9. LED life: 100,000 hours (accelerated test)
10. Burn-in: 168 hours at +65°C

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, hard plastic clamshell case, desiccant. Double-wall box with “SAFETY CERTIFIED,” “SIL 2” labels. SIL 2 certificate laminated. Safety manual (150 pages) included. Diagnostic software on USB drive. Each board ships individually. Factory site visit recommended for first-time SIL 2 integration. Contact us for safety application engineering support.
