GE DS215KLDCG1AZZ03A
Product Name: KLDC Key LED Display Operator Interface Card
Product Introduction: The DS215KLDCG1AZZ03A is a rack plug-in operator station man-machine interface display and keyboard driver board for the GE Speedtronic Mark V IOS (Integrated Operator Station). It acts as the bridge between the Mark V DMC main processor and the front-panel LED/key assembly of a local turbine operator console.
Detailed content
Technical Specifications:
- Manufacturer: GE Fanuc (now Emerson)
- Platform: GE Speedtronic Mark V turbine control system
- Status Indicators: 32 white LEDs (DS1–DS32)
- Connection: 40-pin male connector (3PL)
- Onboard Components: 6 ICs (top half), 12 ICs (bottom half), 2 EPROMs, 3 yellow resistor networks (top), 19 yellow resistor networks (bottom), 6 large resistors, multiple diodes, 3 relays, and small/large yellow capacitors
- Functional Revision: 1A; Artwork Revision: 1Z
- PCB Coating: Normal coating (conformal coat for dust/moisture protection)
- Factory-Drilled Mounting Holes: Yes (corners and center of sides)
- Weight: 1.07 lb (0.48 kg)
- Operating Temperature: –20 °C to +45 °C (standard); –20 °C to +65 °C (extended ventilation)
- Storage Temperature: –40 °C to +85 °C
Functional Features:
- Drives the full-panel LED alarm/status lamps on the IOS front panel
- Scans the membrane key matrix and uploads operator commands to the main CPU via ARCNET rack bus
- Receives real-time operating data, alarm states, and interlock fault signals from the DMC processor
- Latches alarm signals and processes local trip/reset key interlock logic
- Onboard firmware storage for unit-specific display and key-mapping logic
- Built-in hardware self-diagnostics for ARCNET link faults, key matrix open/short, and LED drive overload
Application Scenarios: Gas turbine, steam turbine, and combined-cycle power plant local IOS operator consoles for real-time turbine speed, load, temperature, flame state, overspeed alarm, and emergency trip indication.
Installation Requirements:
- Mount via factory-drilled holes at the board corners and side centers
- Insert the 40-pin male connector (3PL) firmly into the mating socket on the Mark V rack backplane
- Must be paired with a DMC main CPU board, rack backplane, power supply module, and the IOS front-panel key/LED assembly to form a complete operator station
Usage Precautions:
- This card cannot operate standalone; it requires the complete Mark V IOS assembly
- Available only as refurbished, surplus, or remanufactured since it is a discontinued legacy spare
- Handle with ESD protection during installation
