Description
5. Stability and Reliability
Robust Design
The MVME162PA – 344SE is built with a rugged enclosure that provides protection against dust, moisture, and mechanical vibrations. This makes it suitable for use in harsh industrial and power system environments, where these factors can affect the performance of electronic devices.
Redundant Power Supply
Some models of the MVME162PA – 344SE may be equipped with a redundant power supply. In case of a power failure in one supply, the other can take over immediately, ensuring continuous operation of the device and preventing data loss or system downtime.
Error – Detection and Self – Recovery
It has built – in error – detection mechanisms that can detect and diagnose faults in real – time. It can also perform self – recovery operations, such as restarting a malfunctioning module or switching to a backup communication path, to maintain system stability.
6. Parameter Specifications
Power Supply
It operates on a 5V DC power supply, with an allowable voltage range of 4.75V to 5.25V. This narrow voltage range ensures stable and accurate operation of the device.
Memory
- RAM: It is equipped with 128 MB of RAM, which can be expanded to 256 MB. This provides sufficient memory for running complex applications and storing data.
- Flash Memory: It has 16 MB of flash memory for storing the operating system, application software, and configuration data.
Communication Interfaces
- Ethernet: It has one Ethernet port supporting 10/100 Mbps data transfer rates, allowing for high – speed data communication with other devices in the network.
- Serial Ports: There are two serial ports (RS – 232) for communication with legacy devices or for debugging purposes.
- Parallel Port: It also has a parallel port for data transfer with other parallel – compatible devices.
2. Applications
Power Systems
- Substation Automation: As shown in the above case, it is used for real – time monitoring and control of power distribution in substations. It helps to ensure the safe and efficient operation of the power grid by quickly responding to faults and adjusting power flow.
- Power Generation Control: In power plants, it can be used to control the operation of generators, turbines, and other power – generating equipment. It can optimize the power output based on the demand from the grid.
Industrial Automation
- Manufacturing Plants: In factories, it can be used for controlling production lines, robots, and other automated equipment. It can coordinate the operation of different devices to improve production efficiency and product quality.
- Process Control: In chemical, pharmaceutical, and other process industries, it can be used to monitor and control chemical reactions, temperature, pressure, and other process parameters.
3. Weight and Dimensions
- Weight: The MVME162PA – 344SE weighs approximately 2.2 kg. This weight is relatively manageable, which is convenient for installation and maintenance, especially in confined spaces within control cabinets.
- Dimensions: It has dimensions of about 240 mm in length, 180 mm in width, and 65 mm in height. These compact dimensions allow it to be easily installed in standard 6U VMEbus racks, which are commonly used in industrial and power system applications.
4. Features
High – Performance Processor
It is equipped with a high – performance processor that can handle complex computational tasks and process large amounts of data in real – time. This enables fast decision – making and control in dynamic industrial and power system environments.
VMEbus Compatibility
The MVME162PA – 344SE is designed to be compatible with the VMEbus standard. This allows it to be easily integrated into existing VME – based systems, providing a cost – effective solution for system upgrades and expansions.
Multiple Communication Interfaces
It offers multiple communication interfaces, including Ethernet, serial ports, and parallel ports. This allows it to communicate with other devices in the system, such as sensors, actuators, and human – machine interfaces (HMIs), facilitating seamless data exchange and system integration.
1. Real – world Case
In a large – scale power grid substation, the MVME162PA – 344SE was deployed to manage and monitor the distribution of electrical power. One day, a sudden fault occurred in a particular section of the grid, causing an abnormal surge in current and voltage. The sensors connected to the MVME162PA – 344SE immediately detected these changes and sent the data to the unit.
The MVME162PA – 344SE rapidly analyzed the data, identified the fault location, and initiated a series of control actions. It sent commands to the circuit breakers to isolate the faulty section, preventing the spread of the fault to other parts of the grid. At the same time, it adjusted the power flow in the healthy sections to maintain a stable power supply to the consumers. Thanks to the quick and accurate response of the MVME162PA – 344SE, the substation was able to restore normal operation within a short period, minimizing the impact on the power grid and the end – users.
