IS215UCVEH2A is a printed circuit board component of the Mark VI SpeedTronic series. It is a Versa-Module European controller card. The VME card of a turbine system plays an essential role in the smooth running of a turbine. There are many roles IS215UCVEH2A plays in the operations of a turbine. Before we get into that, let us have a quick review of what a VME card is and how does it function.
VME Card
VME or Versa-Module European controller card was first designed and marketed in 1987. Since then, it has seen a boom in its use and is currently in use. Although it is based on European designs of cards, mechanicals, and connectors, one thing it makes it better than the Eurocards is its very own signaling system. The card is standardized by the International Electrotechnical Commission and holds recognition and verification from the American National Standards Institute and Institute of Electrical and Electronics Engineering.
There are numerous tests for the validation and certification of the VME controller cards. As it is applicable mainly in large machinery and equipment, the tests must also be appropriate. Therefore, there are tests for the connector boards to check for their resistance against vibration ranges, shock, and temperature. If they are less resistant, then the resistance ranges towards these physical setbacks like shock and harsh temperature.
Functions of a VME card
Although they were initially designed and manufactured for smaller equipment. But, after seeing their potential in other electronic and technical machinery, they are now regularly used in many industrial types of machinery, like the turbine control system, and even in warfare types of machinery like missiles systems and defense applications.
VME cards also play a crucial role in medical appliances, research projects, and numerous semiconductor process controls.
Mark VI SpeedTronic Series
The Mark VI series is exclusively a turbine control system. It is responsible for controlling and protecting the turbine control system. It also monitors the system of mechanical drive application and generator gas and steam turbines.
The Mark VI series is a far more advanced system than the previous series by General Electric. It exceeds the performance of its predecessors of Mark IV and Mark V as it is an ideal machinery for a close-knit power balancing of the plant. The designs of the hardware and software of the Mark V series are very intricate and are a perfect match for General Electric’s turbine design engineering and controlling engineering system. It is to ensure that the Mark VI control system produces the best results optimum performance of the turbine and the consumers get the best product that money can buy.
Mark VI design and specifications
The best part of the Mark VI Turbine Control System is its Control Module. This is a 13 or 21 slot standard VME card rack. The Control Module receives the input through its termination boards. These termination boards can be box type or barrier type.
Each Input/output card comprises a TMS320C32 DSP processor that filters the data digitally before converting it to a 32-bit IEEE-854 floating-point format. Afterward, the data is stored in a dual-port memory accessible by the onboard C32 DSP side by side with the VME bus.
Besides I/O cards, there is an internal communication card, the main processor card, and a flash disk card in the Control Module. These cards are made with the help of surface-mounted technology and have a conforming coating as per the IPC-8830 guidelines.
Moreover, the I/O data transmits through the VME backplane. It runs through the Input/output and the VCMI card.
The IS215UCVEH2A card specifications
The IS215UCVEH2A is a top-of-the-line product of GE. It is best to use steam and turbine systems for simplex systems or set up triple modular redundancy systems.
Furthermore, the IS215UCVEH2A has a front faceplate equipped with three LED lights on the board’s top. They mainly fulfill the purpose of indicators. The faceplate has General Electric’s logo embedded along with the board ID. It also includes two screws to assist the plate’s holding during set-up.
Some other components on the faceplate include:
- Mezzanine card
- Reset button
- Extra LEDs
- LAN port
- SVGA and Ethernet ports
Additionally, the board’s surface carries a couple of lithium batteries and a MicroSD card. The integrated circuits store various functions for the gas and steam turbine control systems. For instance, Turbine Block Library Control Functions are also integrated circuits. The IS215UCVEH2A board also comprises other components, including:
- Resistors
- Capacitors
- Chokes
