GE IS200WPDFH2A RELAY DAUGHTER BOARD, GENERAL ELECTRIC

الوصف

The GE IS200WPDFH2A is a Relay Power Distribution Daughter Board for the Mark VI series of GE’s Speedtronic Gas Turbine Control Systems. It is a specialized, optional board that works with a main I/O card to provide power and protection for field relays. The ‘H2A’ in the part number indicates it is a specific hardware revision.

Key Features and Functionality

The IS200WPDFH2A is crucial for the safe and reliable operation of relay outputs in a turbine control system. Its main functions include:

• Power Distribution: The board provides power for the relays that drive field devices. It is designed to work with various power sources, including 125 VDC, 115 VAC, or 24 VDC, depending on the system’s configuration.
• Fused Circuits: A primary feature of the board is its fused circuits. It typically has multiple fused branches to protect individual relay circuits from overcurrents or short circuits. This prevents a single fault in the field from affecting the entire I/O card or the control system.
• Diagnostics: The board includes diagnostic capabilities, such as voltage monitoring. If a fuse blows, the board can detect the loss of voltage and send an alert to the main controller. This enables quick troubleshooting and maintenance.
• Daughter Board Design: The IS200WPDFH2A is a daughter board that plugs directly into a compatible main VME card, such as a contact in/relay out card (e.g., VCRC). This modular design simplifies installation and replacement.
