170M5810D  EATON Memory Board, Dynamic

Product  Description：

The EATON Dynamic Memory Board is a specialized internal circuit board or accessory card, typically volatile Random Access Memory (RAM), used within certain EATON industrial control devices like PLCs or drive controllers. Its purpose is to function as the high-speed working memory for the host processor. This board holds the active program variables, real-time data logs, temporary calculation results, and the system stack during operation. It enables the main processor to access and manipulate data rapidly, which is essential for the high-speed execution of control loops and complex logic. The board connects directly to the host system's main bus or CPU board via a custom slot or connector. It is often associated with legacy or specific high-performance EATON control platforms.

Product Parameters (General/Representative)

The exact parameters are specific to the part number, but generally include the following characteristics. The Memory Type is typically DRAM (Dynamic Random Access Memory), which requires continuous refreshing. The Capacity can range from kilobytes (KB) to megabytes (MB), for example, $128 \text{ KB}$ or $512 \text{ KB}$. The Access Speed is measured in nanoseconds (ns) and is optimized to match the controller’s processor. The operating voltage is specific to the host system, commonly $+5 \text{ V}_{\text{DC}}$ or $+3.3 \text{ V}_{\text{DC}}$. The Form Factor is a custom-designed Printed Circuit Board (PCB) tailored to fit a dedicated slot inside the control unit. A critical parameter is that its Data Retention is Volatile, meaning all data is lost upon power removal unless a backup source is utilized by the host controller.

Product Advantages

The primary benefit of using this dynamic memory board is its high-speed operation, offering faster read and write speeds compared to non-volatile memory, which allows the processor to execute complex control logic and mathematical functions in real time with low latency. Historically, this memory type offered cost-effectiveness by providing high memory density at a lower price point than static RAM. As an Original Equipment Manufacturer (OEM) component, it guarantees seamless integration and full compatibility with the specific EATON controller's hardware and firmware. It provides a large, fast area for temporary data handling, necessary for buffering high-frequency I/O updates and process data.

Important Considerations (Precautions)

Several essential precautions must be observed. Due to its volatility, it must be understood that all data on this board is lost when power is removed. The system must be set up to reload the control program and initial values from a non-volatile source during startup. The host controller often requires a backup power source, such as a battery or supercapacitor, to retain critical data or variables during short power interruptions. Extreme care must be exercised during installation to prevent damage from Electrostatic Discharge (ESD), as memory modules are highly sensitive. The specific board must be fully compatible with the exact model and series of the EATON controller to ensure correct electrical and communication interfacing.

Product Applications

The EATON Dynamic Memory Board is used in industrial applications demanding rapid, complex control execution and extensive real-time data handling. This includes high-speed manufacturing systems controlling synchronized motion in equipment like packaging or printing machines where variables require rapid and constant updating. It is critical in process control for controllers managing complex processes that rely on continuous, high-resolution sensor data and fast execution of proportional-integral-derivative (PID) loop calculations. It also functions as a replacement or upgrade module in legacy EATON (Cutler-Hammer) PLC and drive systems that were built around this specific memory architecture. Furthermore, it provides the necessary temporary storage for data logging and buffering of high-volume I/O before transfer to slower, more permanent storage or communication networks.
