Configured for fuel pressure regulation in Mark V Speedtronic systems, the GE DS200XDSAG1A (DS200XDSAG1A Management Board) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

The DS200XDSAG1A serves as a specialized interface board within the Mark V control architecture. Given the single-part designation provided in the technical documentation, no further hardware variations or sub-variants exist for this specific catalog number.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The GE DS200XDSAG1A utilizes RS-422 serial protocols to maintain deterministic communication with external sensing elements, such as Honeywell Smart Pressure Transducers. The board facilitates low-latency data acquisition across its 12 input channels, ensuring that fuel pressure variables remain within defined setpoints for turbine stability. It supports redundant sensor input architectures to ensure signal continuity. The integrated logic is capable of driving a 125 VDC trip solenoid directly upon detection of pressure deviations. Firmware flash compatibility is strictly mapped to the Mark V Speedtronic platform requirements; mismatched firmware versions will lead to communication latencies or failure to initialize the RS-422 interface.

Frequently Asked Questions

Q: Does this board support hot-swapping during turbine operation?

A: No. The board must be de-energized by disconnecting the 28 VDC power supply and isolating the 125 VDC trip solenoid circuit before extraction from the rack to prevent electrical transients.

Q: How should the RS-422 interface be terminated to prevent signal reflections?

A: The RS-422 data lines require proper termination at the receiving transducer end to maintain signal integrity over the serial link, consistent with standard multi-drop serial bus configuration practices.

Field Installation Guidelines

• Mounting: Ensure the board is firmly seated in the Mark V chassis slot to guarantee electrical contact with the backplane connector.
• Shielding: All signal cabling for the 12 input channels must use twisted-pair shielded cables, with shields grounded at a single point to prevent ground loops.
• Solenoid Wiring: Given the 125 VDC output, use high-temperature insulation wire rated for the full voltage and current load of the trip solenoid.
• Environmental: Although rated for -40 deg C to +85 deg C, ensure airflow paths remain clear of obstructions to facilitate heat dissipation from the +5 VDC power circuitry.
