DS200UDSAG1A | New Surplus GE PCB

Description

Product Introduction (Anti-Template)

The DS200UDSAG1A is an enhanced data server controller board for the Mark VI turbine control system—the board that manages data acquisition, logging, and historian services for turbine operations with diagnostic LEDs and improved performance. This board collects data from I/O boards, stores historical data, and provides data access to external systems for analysis and reporting.

The ‘UDSA’ in the part number indicates this is a data server controller board. The ‘A’ revision adds diagnostic LEDs per function, improved performance, and better diagnostics. Compared to the UDSAG1 (no ‘A’), the ‘A’ gives you enhanced diagnostics and better monitoring capabilities.

Key Technical Specifications

Compatible Replacement Models

Replacement options depend on your data server requirements and system compatibility.

✅ Drop-in Replacement: The DS200UDSAG1 (no ‘A’) is a direct electrical drop-in—same pinout, same form factor, same processor. The differences: the base model has no diagnostic LEDs and slower performance. If you don’t need diagnostics and your requirements are standard, the base model is a cheaper option (typically 15-20% less). The ‘A’ is the enhanced version.

⚠️ Software Compatible: The DS200UDSAG2 (if available) would be a higher-performance variant. Check compatibility with your system.

⚠️ Software Compatible: The DS200UCIAG1A (CPU controller) is the main CPU, not a data server—only use if you need CPU functionality.

❌ Hardware Incompatible: Any I/O board (TCCAG1, TCDAG1, TCQAF1, etc.) uses different backplane pins and is not suitable as a data server replacement.

Frequently Asked Questions (FAQ)

What’s the difference between the UDSAG1A and the UDSAG1?

The ‘A’ revision adds three improvements:

• Diagnostic LEDs: Enhanced status LEDs showing health status of the data server.
• Enhanced diagnostics: Storage health monitoring, communication health monitoring.
• Improved performance: Faster data acquisition and storage.

The diagnostic LEDs are the key feature—you can see the health status of the data server at a glance without opening ToolboxST.

How do the diagnostic LEDs work on the ‘A’ revision?

The board has multiple status LEDs:

• Power (green): Board is powered.
• Run (green): Data server is running.
• Fault (red): Data server fault detected.
• Communication (green/amber): Network communication active/fault.
• Storage (green/amber): Storage health status.
• Diagnostic (amber): System health warning.

The LEDs are visible from the front of the board without removing it from the rack.

Can I use this board with a Mark VIe controller?

No—the UDSAG1A uses the older Mark VI backplane pinout and architecture. Mark VIe uses a different system architecture. If you’re migrating to Mark VIe, you’ll need the Mark VIe-specific data server boards.

How do I test this board before installation?

Testing the UDSAG1A requires verifying the data server functionality and enhanced diagnostics:

1. Visual inspection: Check for burnt or discolored components. Look for diagnostic LEDs.
2. Power-up test: Apply power. The board’s status LEDs should illuminate in the correct sequence.
3. Firmware check: Read the firmware version via the system interface—should be 3.0 or later.
4. Communication test: Verify communication via Ethernet ports.
5. Data acquisition test: Verify data acquisition at 5ms intervals.
6. Storage test: Verify data storage and retrieval functionality.
7. Diagnostic test: Verify the diagnostic system reports health status correctly.

What’s the most common failure on this board?

Two issues specific to the data server design:

1. Storage failure. The storage media can fail over time—symptom: data logging errors or inability to retrieve historical data.
2. Communication interface failure. The Ethernet ports can fail—symptom: loss of communication with external systems.

If I’m using this board in a SIL-rated safety application, what’s the recommended maintenance interval?

The data server board with enhanced diagnostics is suitable for SIL-2 applications (when used with appropriate redundancy). We recommend:

• Visual inspection: Every 6 months (check diagnostic LEDs)
• Power-up test: Every 12 months
• Communication test: Every 12 months
• Storage test: Every 12 months
• Diagnostic check: Every 12 months (verify health status)
• Full system test: Every 5 years

What’s the lead time for a replacement UDSAG1A?

These boards are moderately available:

• New surplus: 2-4 weeks.
• Refurbished: 1-2 weeks. Ensure the refurbisher has verified the data server functionality and diagnostics.
• Used/as-is: Available, but the storage media is a wear item—test thoroughly before installation.

Is there a direct Mark VIe equivalent?

Yes—the IS200UDSAG1A (Mark VIe version). The architecture is different.

What’s the data acquisition cycle for this board?

The UDSAG1A can acquire data at 5ms intervals—200Hz update rate.

What communication interfaces does this board have?

The UDSAG1A has Ethernet for network communication and the VME backplane for communication with I/O boards and the main CPU.

Can I use this board in a redundant configuration?

Yes—the UDSAG1A can be used in a redundant configuration with two data server boards (primary and secondary). This provides failover capability for critical data acquisition applications. The enhanced diagnostics on the ‘A’ version improve fault detection in redundant configurations.

What’s the storage capacity of this board?

The UDSAG1A has enhanced storage capacity compared to the UDSAG1, suitable for extensive data logging requirements. For specific storage capacity, consult the GE specifications.
