Product Introduction

The DS200STBAG1 is a status annunciator board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides 32 high-visibility LED indicators on the front panel for turbine operating status, alarms, and shutdown conditions.

The STBAG1 mounts in the rack and displays real-time status from the Mark V CPU. LEDs are color-coded: red (alarm/trip), yellow (warning/caution), green (normal/run). The board accepts 16 discrete inputs (24 VDC) from external devices and provides 8 relay outputs for driving external annunciators. Use it for local operator indication, mimic panels, or as a backup annunciator when the HMI is not available.

Key Technical Specifications

Key Selling Points & Differentiators

• 32 front-panel LED indicators – Clear visual status of turbine operation. Red for trips, yellow for warnings, green for normal.
• 16 discrete inputs – Connect external pushbuttons or remote status contacts.
• 8 relay outputs – Drive external horns, beacons, or remote annunciators.
• LED test button – One-touch test of all 32 LEDs. Verify every indicator works.
• Adjustable LED intensity – Dim for control rooms, bright for bright environments.
• Direct backplane mapping – No programming required. LEDs map directly to CPU status bits.
• Custom labeling – Blank label kit included. Write your own alarm descriptions.
• QC includes 72-hour LED burn-in – All LEDs verified for intensity and color.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: How do I assign LED functions?
A: The board reads status bits directly from the Mark V backplane. Bit 0 = LED 1, Bit 1 = LED 2, etc. Configure the CPU to set bits based on turbine conditions. No separate programming of the STBAG1.

Q: Can I change LED colors?
A: LEDs are fixed colors (red, yellow, green) based on position. Some positions are red, some yellow, some green (see silkscreen on board). You cannot change individual LED colors.

Q: What is the LED test button for?
A: Pressing the button lights all 32 LEDs simultaneously. Verify no burned-out LEDs before startup.

Q: Can I use the STBAG1 without a Mark V CPU?
A: No—the board requires backplane communication from a Mark V CPU to drive the LEDs. It cannot function standalone.

Q: What is the maximum cable length for discrete inputs?
A: 1000 ft (300 m) with 18 AWG shielded cable. Use shielded cable for lengths over 100 ft.

Q: What QC tests are specific to the STBAG1?
A: Eight tests:

1. LED intensity: all 32 LEDs within ±10%
2. LED test button: all LEDs light
3. Discrete input threshold: <5 V OFF, >15 V ON
4. Relay operation: 1000 cycles at 1 A
5. Backplane communication: all 32 bits read correctly
6. Isolation: 1800 VAC
7. Temperature: −30°C to +65°C
8. 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. Front panel label kit included. Configuration guide included. LED test tool included.
