This keypad board allows operators to control turbine parameters locally. The DS200KLDBG1A registers button presses and sends commands to the processor. Its counterpart, the DS200KLDBG1AAA, uses identical membrane switch technology and encoder circuits. Both units belong to the Mark V series platform. Each board measures 8.2 inches in length. The width reaches 5.6 inches. Weight sits at approximately 0.6 kilograms.

Technical Specifications for DS200KLDBG1A DS200KLDBG1AAA

The DS200KLDBG1A contains twenty four individual membrane buttons. The DS200KLDBG1AAA shares the same scanning matrix and key layout. Each board integrates one encoder chip for signal processing. Energy storage relies on a 100µF capacitor bank. This bank debounces mechanical contact signals from button presses. The module operates with a nominal 5V DC logic supply. Each button requires 50 grams of actuation force. One flat ribbon cable connects the board to the main controller.

Key Features Table

The circuit board uses high-grade FR4 material for reliable contact sensing. Moreover, it withstands ambient temperatures from -20°C to 55°C. You can mount this board flush against the front panel. Furthermore, the membrane layer prevents dust ingress between keys. Replacement requires no special programming tools for installation. Always verify ribbon cable alignment before swapping either board. This component gives operators direct local control access. Consequently, it reduces reliance on external computer workstations.
