Functional Description

IS210DPWAG1A is a Transducer Power Distribution Terminal Board developed by GE. It is part of the Mark VI series. The terminal board is designed for DIN-rail mounting, ensuring secure installation within the system setup. It accepts input voltage of 28 V dc 5 percent, provided through a two-pin Mate-N-Lok connector. Connectors are available for two independent power sources, allowing for the utilization of redundant supplies to enhance system reliability.

Input Power and Connection

Accepts an input voltage of 28 V DC ±5%, which is supplied through a two-pin Mate-N-Lok connector. The design supports connection to two independent power sources, providing the option for redundant supply configurations. This redundancy feature ensures continuous power delivery — if one power source fails, the second can automatically maintain operation without system interruption.

The input can be derived from a floating isolated voltage source, allowing for flexibility in power supply design and ensuring that ground loops or interference do not affect sensitive control circuits.

Power Attenuation and Monitoring

To facilitate diagnostic monitoring and system management, the board incorporates two 1 kΩ resistors—one connected from the positive input and one from the negative input—to the SCOM (Signal Common) center point. This configuration allows the power source to “float” relative to system ground, providing electrical isolation and noise suppression.

The board also provides attenuated input voltage signals for external monitoring. These signals can be used by system diagnostics tools or controllers to verify input voltage levels, detect anomalies, and ensure stable power supply conditions. This feature enhances system transparency and simplifies maintenance operations by enabling real-time power status tracking.

Output Power Distribution

Provides a regulated output of 12 V DC ±5%, which is distributed to external transducers, sensors, and interface modules via a Euro-style terminal block equipped with screw terminals. The wiring is typically done using AWG#18 twisted-pair conductors, which improve signal integrity and minimize electromagnetic interference (EMI).

The board provides three output terminal pairs, offering a total output current range of 0 to 1.2 A. This capacity ensures compatibility with a wide range of external devices that require stable 12 V DC power, including analog transducers, sensor interfaces, and auxiliary electronics used in turbine monitoring and control applications.

Each output channel is engineered for clean power delivery, reducing electrical noise and ensuring reliable sensor performance, even in electrically noisy environments typical of industrial turbine systems.

Compatibility and System Integration

Designed for seamless compatibility with the XDSAG#AC interface board and other Mark VI system components. This compatibility allows for simplified wiring, efficient signal routing, and reliable power distribution across interconnected modules.

The board’s modular design ensures that it can be easily integrated into existing system configurations or used as a replacement in maintenance and upgrade projects without significant modification. The use of standardized connectors and mounting systems makes it a plug-and-play solution for GE Mark VI control architectures.

Installation Procedure

• Mounting: Securely mount the DPWA assembly on a standard DIN-rail within the designated location in your system setup. Ensure the DIN-rail is suitable for supporting the weight and size of the DPWA assembly.
• Connecting Input Power: Identify connector P1 on the DPWA terminal board designated for input power connection. Connect the input power source, which typically provides a voltage of 28 V dc (5 percent), to connector P1. Ensure proper polarity and secure connections to prevent any loose wiring.
• Utilizing Multiple Boards: If you are using multiple DPWA boards in your setup for redundancy or expanded power distribution-
  • Use connector P2 as a pass-through connection point for the power to additional DPWA boards. This ensures seamless power distribution across multiple boards.
  • If a redundant power input is provided, connect the redundant power source to connector P3 on the DPWA terminal board. Use connector P4 as the pass-through connection point to distribute power to additional DPWA boards in the system.
• Final Checks: Before powering up the system, double-check all connections to ensure they are secure and properly aligned. Verify that input power sources are within the specified voltage range and polarity requirements to avoid any potential damage to the DPWA terminal board or connected devices.
