Functional Description

IS200EXMDG1A is a Exciter MD Feedback Board developed by GE. It is a part of EX2100e excitation system. The board functions as an MD feedback board and features multiple connectors affixed to its surface. The board is obsolete as it is no longer in production by General Electric.

Connectors on the Board

The board is equipped with various connectors, each serving distinct integration purposes within the EX2100 series:

Augat Connectors

• Three-by-Three Connector: Comprising a grid of nine pins, designed for specific and defined functionalities within the system.
• Two-by-Three Connector: Featuring six pins, this connector serves a unique role in establishing connectivity within the board.

Vertical Pin Connectors

These connectors come in different sizes, offering flexibility and versatility in interfacing with other components within the system architecture.

Right-Angled Connector

• A specialized connector designed for precise connections at right angles, optimizing space utilization within the board's layout.
  Female Connection Points and Male Pins
• The board incorporates two female connection points and two male pins, enhancing compatibility and enabling effective connectivity with other system components.

Integrated Components

The board integrates essential components vital for its functionality:

• Metal Oxide Varistors (MOVs): Two MOVs serve as surge protection devices, safeguarding the equipment from potential voltage spikes.
• Relay: This critical component plays a pivotal role in switching and controlling electrical circuits on the board, ensuring operational reliability.

Exciter Software

• The exciter software undergoes configuration and loading directly from the toolbox, where it finds its home within the controllers. This software is visually depicted on the toolbox screen through interconnected control blocks, illustrating the signal flow.
• The Control Scheme Figure on datasheet provides a simplified portrayal of the exciter control system, highlighting its principal control functions. During regular operation, both the generator field and stator currents and voltages are meticulously measured and fed into the control system. Under normal circumstances, the AC regulator is the selected mode of operation.

Frequently Asked Questions

What is IS200EXMDG1A?
It is a Exciter MD Feedback Board developed by GE.

What is the advantage of having redundant control or bridges in an EX2100 Exciter system?
Redundancy in control or bridges enhances system reliability and provides backup in case of component failure, minimizing downtime and ensuring continuous operation.

When should I opt for single control with a single bridge in my EX2100 Exciter system?
Single control with a single bridge is a suitable choice for applications where redundancy is not critical, and cost-effective simplicity is prioritized.

Are there any specific industries or applications where redundant control and bridges are more commonly used with Exciters?
Redundant control and bridges are often preferred in critical applications such as power generation facilities, where uninterrupted operation is essential.

Can I upgrade my existing Exciter system to include redundant control or bridges if it was initially configured with a single control and bridge?
Upgrading to redundant control or bridges may be possible depending on the system's design and compatibility. It's advisable to consult with the manufacturer or a qualified technician for guidance on system upgrades.
