Product Introduction

The DS200SSBAG1B is an enhanced safety shutdown board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides faster response time (<10 ms) and additional diagnostic features compared to the standard SSBAG1.

The “1B” variant adds four extra discrete inputs (12 total vs 8), reduces response time from 20 ms to 10 ms, and adds per-channel input diagnostics (open-wire detection, short-circuit detection). The board monitors critical turbine parameters: overspeed (magnetic pickup sensors), emergency stop pushbuttons, and process trips. When a trip condition occurs, the board directly de-energizes turbine trip solenoids via redundant 10 A safety relays—even if the main CPU has failed.

Key Technical Specifications

Key Selling Points & Differentiators

• <10 ms response time – Twice as fast as standard SSBAG1 (20 ms). Critical for overspeed protection.
• 12 discrete inputs – 4 more than standard. Connect additional trip sensors.
• Input diagnostics – Open-wire detection (sensor broken) and short-circuit detection. LED indicates fault per channel.
• Enhanced overspeed detection – 12 kHz frequency range (standard 10 kHz). Faster turbine speeds.
• Wider temperature range – −40°C to +70°C (standard: −30°C to +65°C).
• SIL 2 capable – Suitable for safety functions up to SIL 2.
• QC includes <10 ms response verification – Measured with oscilloscope.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SSBAG1 (standard) and SSBAG1B (enhanced)?

Q: How does open-wire detection work?
A: The board injects a small current (1 mA) into each input. If no current flows (open wire), the yellow fault LED lights. The input is still considered OFF (safe state). Does not affect normal operation.

Q: Can I retrofit SSBAG1B into a system designed for SSBAG1?
A: Yes—same form factor and backplane connector. The additional 4 inputs have dedicated terminal positions. If unused, leave disconnected.

Q: What is the minimum pulse width for overspeed detection?
A: 83 µs (12 kHz). At 60 Hz, the MPU input is sampled every 83 µs, ensuring accurate speed measurement up to 12,000 rpm (200 Hz) with 6 pulses per revolution.

Q: What QC tests are specific to the SSBAG1B?
A: Ten tests:

1. Response time: <10 ms measured (all inputs)
2. Discrete input diagnostics: open-wire and short-circuit detection
3. MPU frequency range: 10 Hz to 12 kHz
4. Relay operate: 1000 cycles at 5 A
5. Redundancy: 1oo2 per channel
6. Isolation: 3000 VAC
7. Temperature: −40°C to +70°C
8. LED test: all indicators
9. Trip logic: all jumper configurations
10. Burn-in: 72 hours at +65°C

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, double-wall box. Each board ships individually. Safety manual included. Diagnostic guide included. Configuration jumpers included. MPU adjustment tool included.
