Product Description
The DS3800NVIA1G1D from General Electric’s Mark IV Speedtronic line is a voltage isolator board. The Mark IV turbine control system was the first of the Speedtronic line to offer TMR (triple modular redundant) architecture that allowed individual microprocessors to vote on outputs. This type of control significantly reduced downtime for the gas and steam turbine systems that used it, while maintaining costs. The Mark IV used a modular design to allow users to create a system specifically tailored to their needs.
The DS3800NVIA1G1D functions as a voltage isolator board. The board helps suppress spikes in voltage from causing damage to the system. The board is a rectangular board with components mounted to one side only. Components are mounted using TH (through-hole) technology. Additionally, the board includes a backplane for interfacing with the rack system and has stand-offs pre-inserted into its surface to help users install an auxiliary board if it is desired. Additionally, the board has a line of twelve vertical pins that will help the auxiliary interface with the primary board. These pins are numbered one through twelve. It is important to note no auxiliary is included with this purchase.
The DS3800NVIA1G1D is populated with integrated circuits, resistors, transistors, diodes, and capacitors. The right edge has a line of TP test points, a line of LED indicators, and three toggle switches. One of the LEDs is yellow and four are red. The toggle switches are individually labeled and will be available to users after installation. For more information refer to GE manuals and user guides.
