FMVA20LCYUNV176 EATON

FMVA20LCYUNV176 EATON Memory Board, Dynamic

Product  Description：

An EATON Dynamic Memory Board functions as an expansion module to increase the available volatile memory in a specific EATON control platform, such as older PLC systems or specialized power quality monitoring equipment. It provides the high-speed storage necessary for complex control programs, extensive data logging, and multitasking operations. The memory is typically organized into addressable locations, allowing the CPU rapid read and write access.

Product Parameters (Typical)

Parameters are highly dependent on the specific system or series the board is designed for (e.g., legacy Cutler-Hammer or newer EATON systems).

• Memory Type: Dynamic Random Access Memory (DRAM).

• Capacity: The total amount of volatile memory provided (e.g., 512 KB, 1 MB, 4 MB).

• Access Speed: The speed at which the CPU can read from or write to the memory (e.g., measured in nanoseconds).

• Bus Interface: The type of backplane or system bus the module connects to (e.g., proprietary bus, VMEbus).

• Power Consumption: The electrical power required for operation and refresh cycles.

• Operating Voltage: The voltage required from the system backplane (e.g., +5 VDC).

• Form Factor: The physical size and connector type designed to fit into a specific EATON controller rack.

• Error Correction: May include features like Parity Check or Error-Correcting Code (ECC) depending on the system's requirements.

Product Advantages

• Enhanced Performance: Provides the necessary storage for faster program execution and more complex algorithms by reducing reliance on slower storage media.

• Increased System Capability: Allows the CPU to handle larger user programs, manage more variables, and execute more sophisticated control strategies.

• Data Intensive Operations: Essential for applications requiring extensive real-time data logging, temporary calculations, and buffering of communication data.

• Cost-Effective Expansion: Offers a modular way to upgrade the memory capacity of existing control systems without replacing the entire processor.

• Reliability: Designed and tested to meet industrial standards for electromagnetic compatibility and resistance to vibration and temperature fluctuations.

Precautions

• Volatile Nature: Being dynamic memory, all data is lost upon power removal. Proper system configuration must ensure critical data is backed up to non-volatile memory (like Flash or battery-backed RAM) before power loss.

• Compatibility: Verify the board's part number and revision level are fully compatible with the specific CPU module and chassis being used.

• Installation: Follow anti-static (ESD) procedures strictly when handling and installing the board to prevent damage to the memory chips.

• Power Requirements: Ensure the system power supply has adequate capacity to support the additional current draw of the memory board.

• Operating Environment: The module must be operated within the temperature and humidity specifications of the control system enclosure.

Product Applications

EATON Dynamic Memory Boards are typically used in industrial automation and power management systems where high-speed, temporary data storage is required.

• Programmable Logic Controllers (PLCs): Used to hold the operational program, input/output status tables, and temporary calculation results within the CPU module.

• Power Quality Monitoring: Employed in dedicated EATON power management devices to buffer high-speed data samples, event logs, and transient fault recordings before transfer to permanent storage.

• Industrial Automation Systems: Used in various EATON control platforms requiring large data arrays for recipe management, batch control, and sequential control applications.

• Communication Buffering: Providing memory space for buffering incoming and outgoing data for high-throughput communication modules.
