Input/Output Architecture and Signal Processing
The GE DS200STBAG1ACB excels at managing diverse signal types for comprehensive turbine drive control. Its multi-input/output architecture handles both analog and digital signals simultaneously.
Digital Inputs: The board accepts 24 discrete digital signals from field sensors. Each input features opto-isolation for protection against voltage transients.
Analog Channels: It processes 8 differential analog input channels with 12-bit resolution. Consequently, you receive accurate readings from speed and temperature sensors.
Output Capabilities: The terminal board provides 16 digital output channels for drive commands. These outputs can sink up to 0.5 Amps each for direct relay control.
Signal Conditioning: Onboard filtering circuits remove high-frequency noise from incoming signals. This ensures clean data transmission to the main turbine controller.
Onboard RAM and Data Storage Features
A standout feature of the GE DS200STBAG1ACB includes its onboard RAM for temporary data storage. This memory capability supports critical turbine control functions.
Memory Type: The board utilizes 512 KB of static RAM for data buffering. This volatile memory requires continuous power to maintain stored information.
Battery Backup: A lithium battery maintains RAM contents during system power-down. The battery provides approximately 10 years of data retention under normal conditions.
Data Storage: The RAM stores configuration parameters and calibration data locally. Therefore, the board retains critical settings even after complete power loss.
Access Speed: The memory interfaces with the main processor at 55 ns access time. This enables rapid read/write cycles for real-time control applications.
Integration with Mark V Drive Systems
The GE DS200STBAG1ACB serves as a vital link in the Mark V turbine control architecture. It works alongside other modules like the IS200AEBMG1AFB to ensure comprehensive drive regulation.
Backplane Communication: The board connects to the VME backplane through dual 96-pin connectors. This interface transmits processed signals to the main control processor.
Field Wiring: Terminal blocks accept wiring from external devices without special tools. This simplifies installation and maintenance in the field.
Status Indication: Multiple LED indicators show power status and signal activity. Operators can quickly verify board operation during routine inspections.
Environmental Rating: The GE DS200STBAG1ACB operates reliably from -30 to 65 degrees Celsius. This wide temperature range suits demanding power generation environments.
