Product Introduction
The DS200STBAG1ACB is a high-visibility status annunciator board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides 32 ultra-bright LEDs (25,000 mcd) that are readable in direct sunlight, making it suitable for outdoor cabinets and high-ambient-light environments.
The “ACB” suffix represents the high-visibility variant. Features: 32 ultra-bright LEDs (25,000 mcd red, 20,000 mcd yellow/green), sunlight-readable even at 100,000 lux, IP54-rated front panel (dust and water resistant), extended temperature range (−40°C to +75°C), and conformal coated PCB. Use it for outdoor turbine installations, offshore platforms, desert environments, or any location with high ambient light.

Key Selling Points & Differentiators
- Ultra-bright LEDs (25,000 mcd) – 12x brighter than standard STBAG1A (2,000 mcd). Readable in direct sunlight.
- Sunlight readable – 100,000 lux ambient light. Perfect for outdoor cabinets, desert installations, offshore platforms.
- IP54 front panel – Dust protected and water resistant. Gasket kit included for panel mounting.
- Extended temperature range (−40°C to +75°C) – Operates in extreme environments. Standard board rated −30°C to +65°C.
- Conformal coated PCB – Protects against humidity, condensation, salt spray.
- Narrow viewing angle (30°) – Visible from long distance (50+ meters). Standard board is 120° (near field).
- Optional sun shield – Reduces glare from overhead sun. Available as accessory.
- QC includes sunlight readability test – Verified at 100,000 lux (simulated sunlight).
- 2-year warranty
Frequently Asked Questions (FAQ)
Q: What is the difference between STBAG1A (standard) and STBAG1ACB (high visibility)?
| Feature | STBAG1A | STBAG1ACB |
|---|---|---|
| LED intensity (red) | 2,000 mcd | 25,000 mcd |
| Sunlight readable | No | Yes (100,000 lux) |
| Viewing angle | 120° (wide) | 30° (narrow) |
| IP rating (front) | None (indoor only) | IP54 |
| Temp range | −30 to +65°C | −40 to +75°C |
| Conformal coating | No | Yes |
Q: Can I see the LEDs from 100 feet away?
A: Yes. The narrow 30° viewing angle concentrates light. At 100 ft (30 m), the LED spot size is 16 ft wide—easily visible. For longer distances (200+ ft), optional magnifying lens available.
Q: Do I need a sun shield?
A: Recommended for outdoor installations where sunlight directly hits the panel from above. Sun shield reduces glare and improves contrast. Not needed if the panel is shaded or indoors.
Q: Is the board waterproof?
A: IP54 is not waterproof (IP67 is). It resists splashing water and dust. Do not pressure wash. For full waterproofing, order optional IP67 enclosure (special order, 4 weeks).
Q: What is the IP54 gasket kit?
A: Included. A foam gasket seals between the board’s front panel and your cabinet door. Ensures dust and water do not enter through the cutout.
Q: What QC tests are specific to the ACB revision?
A: Ten tests:
- LED intensity: 25,000 mcd red, 20,000 mcd yellow/green
- Sunlight test: 100,000 lux ambient, LEDs visible
- Viewing angle: 30° ±5°
- IP54 verification: dust and water spray test
- Temperature: −40°C to +75°C
- Conformal coating: thickness 0.05 mm ±0.01 mm
- Discrete input threshold
- Relay operation
- Isolation: 3000 VAC
- Burn-in: 168 hours at +65°C
Q: What shipping protection?
A: Anti-static bag, ESD foam cradle with LED lens protector, double-wall box with “FRAGILE” labels. Each board ships individually. Gasket kit included. Conformal coating touch-up pen included. Sun shield optional (order separately). Do not touch LED lenses during installation.
