Functional Description

DS215UDSAG1A is a Display/Keyboard Interface Board with Firmware developed by GE. It is a part of EX200 series. This board plays a role in the human-machine interface (HMI) segment of control systems, allowing operators to interact effectively with the system through display feedback and keypad inputs. It enables clear data visualization and efficient command entry. It integrates seamlessly into the EX200 excitation system platform, supporting real-time monitoring, control, and diagnostics of turbine and generator systems.

Major Hardware Components

The board includes several key hardware components that ensure smooth operation and system integration:

• -24 V to +5 V Switching Power Supply: Capable of delivering a minimum of 3 A at 5 V, this power unit ensures stable operation for all onboard components.
• Microprocessor Core: Serves as the central processing unit, managing input/output operations, interfacing with firmware, and supporting real-time processing functions.
• RS-232C Interface Circuitry: Facilitates serial communication between the interface board and other system components, allowing data exchange and firmware updates.
• Keypad Scanning Interface Circuitry: Detects and processes inputs from the keypads, enabling quick and accurate response to user commands.
• Key Status LED Interface Circuitry: Controls the LED indicators associated with each key, providing visual feedback for operational status and diagnostics.
• Display Driver Circuitry: Manages the output to the dot matrix display, ensuring clear and precise text and symbol rendering.
• Pulse-Width Modulated (PWM) Dimmer Circuitry: Controls the brightness of key LEDs and the display for optimal visibility in different lighting conditions.

Display and Keypad Interface

• Dot Matrix Display: Two rows of 40 characters for detailed system messages and instructions. One additional row of 12 characters for status updates or alerts. The display offers high readability, aiding in effective monitoring.
• Dual Keypad Layout (48 Keys Total):
  • Keypad 1: 32 configurable keys, arranged in two sets of 16, each equipped with status LEDs for real-time feedback and customizable system functions.
  • Keypad 2: 16 keys dedicated to numeric data entry, local control functions, and diagnostic operations.
  • This combination of display and input functionality makes the DS215UDSAG1A an essential tool for operational control and diagnostics within GE's EX200 excitation systems. It offers flexibility, user-friendly design, and durability suited to mission-critical applications in power generation and industrial automation.
