About the DS200DCVAG2A
The DC Power and Instrument Board DS200DCVAG2A is part of the Mark V Series produced by General Electric. The Mark V Series that this DS200DCVAG2A product offering belongs to is definable as one of the final General Electric Mark product series to make use of the retailer's patented Speedtronic control system technology first introduced alongside the rollout of the Mark I Series in the late 1960s.
This DS200DCVAG2A DC Power and Instrumentation Board is reinforced for its intended functional Mark V Series role through its assembly's adoption of a singular A-rated functional product revision.
DS200DCVAG2A Hardware Tips and Specifications
As with any Mark V Series product, this DS200DCVAG2A PCB makes use of its own series of functionality-inducing hardware components and component specifications. This board is primarily used with turbine control systems, these systems have the capability to be fully programmed. This board has online maintenance, built-in diagnostics, and a common hardware platform that allows for this board to be used with steam and gas applications. The built-in diagnostics for this board include:
- background routines
- power-up routines
- manually initiated diagnostic routines
All of the routines of this board have the ability to identify sensor, output device, and control panel faults.
DS200DCVAG2A I/Os
The DS200DCVAG2A board also has inputs and outputs which are designed for direct interfacing with the following generator and turbine devices, some of these devices are:
- thermocouples
- servos
- LVDT/Rs
- magnetic speed pickups
All of the contact inputs on this board are optically isolated and will receive a time stamp within one millisecond of a status change within the system. There are internally powered outputs which are also known as solenoid outputs. There are several ungrounded thermocouple types on the DS200DCVAG2A board, each thermocouple has an RTD type, for example, the K thermocouple is an RTD of 120 Ω nickel. The thermocouples and RTDs are used with linearization for various sensor types. All information regarding this board can be found in the GEI-100460 Speedtronic Mark V Product Description Manual. There are other General Electric publications and manuals that can also be used when operating the DCVA board in a Mark V System.
