Based on the provided information, the GE DS200UPLAG1B is a crucial component within GE’s industrial control systems, but the user’s provided description is slightly inaccurate. It is not the main processor card, but rather a Power Supply/LAN Interface Board. It is a key part of the Mark V and EX2000 series, and its “no/fw” designation indicates that it has no onboard firmware.
Here is a detailed and high-quality description of the board, correcting the initial assumption and providing a comprehensive overview.

2. Brief Product Description
The GE DS200UPLAG1B is a specialized Power Supply/LAN Interface Board designed for the GE Speedtronic Mark V and EX2000 series control systems. Its primary function is a dual role: to provide power to critical components, specifically the OC2000 Operator Interface Module, and to manage communication via a Local Area Network (LAN) interface. This board integrates power conversion circuits with network connectivity, enabling seamless data communication and ensuring a stable power supply for networked devices within industrial control systems. The “no/fw” in its description indicates that this specific revision does not come with pre-loaded firmware.
- Part Type: Power Supply / LAN Interface Board
- Primary Function: Provides power for the OC2000 operator interface and manages LAN communications.
- Compatibility: GE Speedtronic Mark V and EX2000 series.
- Application: Turbine control systems, especially in power generation.
3. Detailed Product Description
In the complex and demanding environment of a power plant, a single board can perform multiple critical functions to save space, reduce complexity, and increase reliability. The GE DS200UPLAG1B is a perfect example of this integrated engineering philosophy. From my expertise, this board is not a main processor but a crucial support component that enables the operator interface to function and communicate with the main control systems. It is the bridge between the system’s power sources and its human-machine interface.
A Closer Look at the DS200UPLAG1B
The DS200UPLAG1B is a specialized circuit board that integrates two vital functions into a single card. This integration is particularly useful in the compact and robust cabinets of the Mark V and EX2000 series. Its key functions are:
- Power Supply: It acts as a power supply for the OC2000 operator interface module. It takes in AC power (typically 115/230 VAC, 50/60 Hz) and provides regulated DC power (+/-24V and 5V) to the interface. This ensures the OC2000 has a clean, stable power source, which is critical for its reliable operation.
- LAN Interface: The board also provides the network connectivity for the control system. It allows for real-time communication between the turbine’s control system and the plant’s wider network (such as a SCADA system). This is essential for remote monitoring, data logging, and supervisory control.
The “no/fw” or “no firmware” designation is a key detail. This means that the board’s core functionality is hardware-based and it does not require a software upload. This distinguishes it from other processor cards that need specific firmware to be loaded for a particular application. This design makes it a versatile and reliable component that can be used across different system configurations.
The board’s physical features include a fuse for overcurrent protection, a toggle switch, and a reset button that allows for a quick restart of the board without a full system reboot, which is a valuable feature for troubleshooting. It also features several configurable jumpers and DIP switches for setting up its operation, which makes it adaptable to various installation requirements.
Key Features and Benefits
- Integrated Design: The combination of power supply and LAN interface on a single board reduces the number of components, simplifying cabinet layout and reducing potential failure points.
- Dedicated Power Source: By providing a dedicated and stable power source for the OC2000 operator interface, it isolates it from potential power fluctuations in the main control system.
- Robust Communication: The LAN interface enables high-speed data transfer, facilitating remote monitoring and control of the turbine from a central control room.
- Onboard Diagnostics and Controls: Features like the reset button and status LEDs simplify troubleshooting and maintenance.
- Industrial-Grade Construction: The board is built to withstand harsh industrial environments, featuring a normal PCB coating that provides a basic layer of protection against dust and moisture.
