GE DS215KLDBG1AZZ03A stores energy using one electrolytic capacitor. This capacitor provides 22 µF at 35V rating for key debounce filtering. Consequently, the board prevents false key readings during 10 millisecond power fluctuations. Therefore, operator inputs remain accurate in noisy industrial environments.
Design and Integration
This circuit board uses two-layer PCB construction with ESD protection diodes on all key inputs. Consequently, the GE DS215KLDBG1AZZ03A operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 100 mA typical current from the 24V DC supply. The LCD interface supports standard character display modules. We recommend mounting the board behind a sealed front panel for environmental protection.
Practical Application
This circuit board provides local operator interface for GE drive and turbine systems. It reads key presses and updates the LCD screen with system parameters. The GE DS215KLDBG1AZZ03A also sends operator commands to the main controller. Therefore, it enables local monitoring and configuration for industrial control applications.
