GE DS200SVAAG1ACB Mark V Servo Valve Amplifier Board

The GE DS200SVAAG1ACB, also cataloged as the DS200SVAAG1A Servo Valve Amplifier Board, operates as a dedicated hardware component for driving electro-hydraulic servo valves within Speedtronic Mark V control systems.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

• The board transfers servo control loop feedback directly across the Mark V backplane bus, driving fast-acting hydraulic actuators with a frequency response bandwidth of 0 to 500 Hz. Closed-loop position accuracy is maintained via integrated LVDT/RVDT excitation circuitry operating at 3.0 V RMS at 4 kHz.
• Hardware handshaking protocols synchronize input signal processing across both differential channels to eliminate output update delays. Onboard firmware algorithms monitor real-time short-circuit and over-temperature diagnostics, passing status vectors to the primary processor board while executing linearity within 0.5% of full scale.

Frequently Asked Questions

Q: What power supplies are required to energize the logic and field output stages of this board?

A: Logic operations require a 5 V DC power supply (+/- 5% tolerance), while the field switching circuits draw operational power from a 24 V DC supply (+/- 10% tolerance).

Q: How does the board maintain signal integrity between low-voltage digital control loops and field actuators?

A: Channel logic is protected by a 2500 V AC isolation barrier between the internal backplane logic and external field wiring circuits.

Field Installation Guidelines

• Verify that all power sources to the Mark V rack assembly are isolated before sliding the 6U Eurocard into its assigned card cage slot.
• Align the board edge connectors carefully with the backplane plane to prevent bent pin connections during insertion.
• Ensure LVDT/RVDT feedback wiring and +/- 10 V DC differential input leads are shielded and grounded at one end to minimize noise interference.
• Fasten front panel retaining screws securely to establish ground continuity and preserve proper air flow across the heat sink components.
