GE DS200DSPCH1ADA Mark V Digital Signal Processor Board

Product Description

DS200DSPCH1ADA is a Digital Signal Processor Control Board designed for integration within the GE Mark V turbine control platform. The board serves as a central processing element responsible for executing time-critical control logic and managing processed signals exchanged across the Mark V backplane. It is engineered for reliable operation in gas and steam turbine environments where deterministic control performance is required.

Technical Specifications

Functional Characteristics

• Executes deterministic turbine control and protection algorithms

• Processes digital and conditioned analog signals for internal system logic

• Provides relay-based control outputs for coordinated system actions

• Supports real-time diagnostics through onboard LED indicators

• Designed for continuous operation in electrically and thermally demanding environments

Application Scope

The DS200DSPCH1ADA board is deployed in GE Mark V gas and steam turbine control systems where high-speed signal processing and control coordination are required. It functions as a processing node rather than a direct field I/O interface, relying on associated Mark V I/O boards for sensor and actuator connections.

Frequently Asked Questions

Q: Does this board connect directly to field instruments?
A: No. This board performs internal signal processing and control logic. Field wiring is handled by dedicated Mark V I/O modules.

Q: What power supplies are required?
A: The board requires a +5 V DC logic supply at 6 A and a 28 V DC control supply within an 18–32 V DC range.

Q: Is it suitable for replacing earlier revisions?
A: Yes. The module maintains backward compatibility with the first two DSPC hardware revisions used in Mark V systems.

Q: How is the board installed?
A: It is designed for DIN-rail mounting within a Mark V control cabinet and must be properly grounded to prevent electrostatic damage.
