DS200SBCBG1ADC | GE Mark V CPU Board High Performance

Description

Product Introduction

The DS200SBCBG1ADC is a high-performance main processor board (Single Board Computer) for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It is the most advanced CPU in the Mark V family, featuring integrated dual Ethernet ports, expanded memory (32 MB DRAM, 16 MB Flash), and a faster 100 MHz processor.

The “ADC” suffix represents the highest-spec revision of the SBCB family. Compared to the base SBCAG1A, the SBCBG1ADC runs at 100 MHz (vs 66 MHz), has 4x the DRAM (32 MB vs 8 MB), 4x the flash (16 MB vs 4 MB), and includes dual onboard Ethernet ports (no mezzanine card required). It also adds a real-time clock with supercapacitor backup, enhanced watchdog timer, and extended temperature range. This board is required for larger turbine applications, faster scan rates, or systems requiring dual redundant Ethernet communication.

Key Technical Specifications

Key Selling Points & Differentiators

• 100 MHz processor, 32 MB DRAM, 16 MB Flash – 50% faster CPU, 4x memory of base SBCAG1A. Handles larger I/O counts (up to 2048 points), faster scan rates (5 ms), and more complex control logic.
• Dual integrated 10/100 Ethernet – No mezzanine card required. Two independent ports support redundant Ethernet networks (separate IP addresses or bridge mode). Supports Modbus/TCP, SRTP, FTP, and embedded web server.
• Real-time clock with supercapacitor – Time stamps alarms and events accurately even during power outages. Supercapacitor keeps RTC running for 7 days without battery. Replace main battery without losing time.
• Extended temperature range (−40°C to +70°C) – Operates in outdoor cabinets, unheated turbine enclosures, or cold climates. Base SBCAG1A is rated 0°C to +60°C only.
• Replaceable socketed battery – Base SBCAG1A battery is soldered. The SBCBG1ADC uses a socketed 3.6 V lithium cell. Replace in 2 minutes without soldering. Spare battery included.
• Firmware upgradeable via USB – Load new firmware from USB flash drive. No special cable or software required. Base board requires serial or Ethernet only.
• QC includes 96-hour burn-in at +70°C – Board runs continuous self-test at elevated temperature. Verified no memory errors, no Ethernet packet loss, no watchdog resets.
• Configuration transfer available – Send us your old board (same model or older SBCAG1A). We extract configuration and convert to SBCBG1ADC format. Upgrade your CPU without rebuilding from scratch.
• 2-year warranty – Covers processor, memory, Ethernet ports, serial ports, RTC, and battery.

Frequently Asked Questions (FAQ)

Q: What is the difference between SBCAG1A (base), SBCBG1A (mid-range), and SBCBG1ADC (high-end)?

Choose ADC for new projects, large I/O counts, or when upgrading from older SBCs.

Q: Can I replace a SBCAG1A with a SBCBG1ADC as a drop-in upgrade?
A: Yes—physically and electrically. Same form factor, same backplane connector, same power requirements. However, you cannot simply move the configuration. The SBCBG1ADC uses a different memory map and requires a different firmware version. You must:

1. Obtain firmware for SBCBG1ADC (v6.0 or higher—we can supply).
2. Convert your configuration using GE’s conversion utility (we provide this service).
3. Reload configuration via USB or Ethernet.
   We offer a complete upgrade service. Allow 1 week for conversion and testing.

Q: Do I need special software to communicate with the SBCBG1ADC?
A: No. Standard Mark V tools (Control System Toolbox, Toolbox for Mark V) work. The dual Ethernet ports appear as two separate network interfaces. Configure via front panel serial port or using the embedded web server (HTTP). Default IP: 192.168.0.101 for Port A, 192.168.0.102 for Port B.

Q: How do I use the USB port for firmware updates?
A: Format USB drive as FAT32. Copy firmware file (extension .SBC) to root directory. Power off board, insert USB drive, power on. Board automatically enters update mode (yellow LEDs flash). Update takes 2–3 minutes. Do not remove USB drive during update. We include detailed instructions.

Q: What is the supercapacitor for, and how long does it last?
A: The supercapacitor (1 F, 5.5 V) powers the real-time clock when the board is powered off AND the main battery is disconnected or depleted. It provides 7 days of RTC backup. When you replace the main battery (every 5 years), the supercapacitor keeps the clock running during the 2-minute battery swap. No need to reset time. Supercapacitor life: 10+ years.

Q: Can I use both Ethernet ports for redundant communication?
A: Yes. Configure Port A and Port B with separate IP addresses on separate subnets. The Mark V software supports dual-network redundancy. If Port A loses connectivity, the system automatically switches to Port B. Failover time <500 ms. Also supports link aggregation (bonding) for double throughput.

Q: What is the maximum I/O capacity of the SBCBG1ADC?
A: Limited by scan rate, not absolute count. With 32 MB DRAM and 100 MHz CPU, typical capacities:

• 2048 digital I/O + 256 analog I/O at 10 ms scan
• 1024 digital I/O + 128 analog I/O at 5 ms scan
• 4096 digital I/O + 512 analog I/O at 20 ms scan (requires firmware v7.0+)
  Contact us for scan rate calculations specific to your configuration.

Q: What QC tests are specific to the SBCBG1ADC?
A: Eleven tests, all documented:

1. Visual: 20x magnification, socketed battery contacts, supercapacitor, Ethernet magnetics.
2. Battery voltage: 3.6 V ±0.2 V (socketed). Spare battery tested separately.
3. Supercapacitor: Charge to 5.5 V, measure voltage after 24 hours with board unpowered. Must retain >3.0 V.
4. DRAM test: Full 32 MB pattern test (alternating, walking 1, walking 0). 2 hours.
5. Flash checksum: 16 MB verified, checksum logged.
6. Ethernet test: Both ports at 100 Mbps full duplex, 10 million packets, 0.01% loss maximum. Loopback via external switch.
7. Serial port test: Loopback at 9600/19200/38400/115200/230400 baud. 2 million bytes each.
8. USB port: Firmware update test (write, verify, rollback).
9. Backplane communication: Address scan, interrupt test, DMA test.
10. RTC accuracy: Measure drift over 24 hours. <2 seconds per day.
11. Burn-in: 96 hours at +70°C, running continuous self-test + Ethernet ping flood. No errors, no watchdog resets.

Q: What shipping protection for this high-value board?
A: Maximum protection. Anti-static bag, ESD foam cradle, hard plastic clamshell case, double-wall box with “HIGH VALUE,” “ESD SENSITIVE,” “FRAGILE” labels. Shock indicator. Calibration and test report (8–10 pages) included. Spare battery shipped separately (not installed—shipping regulations). USB drive with configuration utilities included. Each board ships individually
