The DS3800NADA1E1F is a printed circuit board manufactured by General Electric. It is designed to work as an analog-to-digital converter card within the Speedtronic Mark IV series. The Mark IV, a gas and steam turbine control system, uses integrated chipsets built with intentional redundancies to keep the system running even when an individual board experiences an issue. It does this by using overlapping responsibilities and two-out-of-three voting redundancies on critical controls and protection parameters. In this way, downtime is minimized.
The DS3800NADA1E1F has twenty-six integrated circuits. This includes an analog-to-digital converter chip located at U3. This chip provides all functions necessary for analog-to-digital conversion and combines a 12-bit ADC with an internal clock and a track hold amplifier. It has been tested and fully specified for signal-to-noise ratio, harmonic distortion, and intermodulation distortion. The DS3800NADA1E1F also includes oscillators, up/down binary counters, octal buffers and dual positive-edge-triggered D flip-flops.
The DS3800NADA1E1F has one amber LED, three test points, two extractor clips, and three PCB reinforcement crossbars, which are made of anodized aluminum.
Communications with the DS3800NADA1E1F to other PCBs are made through two connectors, one male, and one female. These are placed on either side of the board.
The DS3800NADA1E1F has two potentiometers, a set of spare PTH, and multiple metal film resistors. It has been marked for alignment along its top edge.
Technical support for the DS3800NADA1E1F, including publications like manuals and data sheets, was provided by General Electric. We recommend referring to guidelines within these publications as needed for information.
