57360001-KG ABB DSMB175 Advant OCS DRAM Upgrade

Product Overview

The ABB DSMB175 (P/N: 57360001-KG) functions as the primary dynamic memory expansion for ABB Advant OCS MasterPiece 200 and 200/1 controllers. This high-performance DRAM board provides the volatile storage necessary for executing complex control logic and managing real-time process data. We supply this module as 100% Brand New and Original, ensuring your legacy DCS hardware maintains maximum uptime and operational stability.

Technical Specifications

The DSMB175 utilizes high-speed DRAM architecture to facilitate rapid data access for the MasterPiece CPU:

Engineering Advantages

The DSMB175 delivers critical hardware benefits for aging yet vital control infrastructures:

• Seamless Capacity Expansion: The 4MB DRAM capacity allows the MasterPiece 200 controller to handle larger application programs and more extensive database tags without triggering memory overflow errors or slowing down scan cycles.

• Plug-and-Play Integration: The board features a standardized direct interface that slides into the existing controller subrack. This design eliminates the need for complex wiring or physical modifications to the cabinet.

• Enhanced System Response: By providing dedicated high-speed dynamic storage, the DSMB175 optimizes the execution of PID loops and sequential logic, ensuring the controller responds instantly to field-side state changes.

• Industrial Reliability: Unlike standard commercial memory, the DSMB175 employs industrial-grade components designed to withstand the thermal and electromagnetic stress of a DCS cabinet environment.

FAQs

Q: Can I install the DSMB175 while the controller is powered on?

A: No. You must power down the MasterPiece 200 controller before inserting or removing memory boards to prevent electrical damage to the backplane and to ensure the CPU correctly initializes the new memory allocation during the boot sequence.

Q: Does this board require manual jumper settings for memory addressing?

A: The DSMB175 is designed for direct integration within the Advant OCS architecture. However, always refer to your specific MasterPiece 200 configuration manual to verify if your existing CPU requires specific address switch settings to recognize the expanded 4MB capacity.

Q: Is the DSMB175 compatible with MasterPiece 200/1 versions?

A: Yes. The DSMB175 provides full hardware compatibility for both the standard MasterPiece 200 and the 200/1 variants, making it a versatile spare part for mixed-generation fleets.

Q: How does this memory board handle data during a power failure?

A: As dynamic memory (DRAM), the DSMB175 requires a constant power supply to retain data. The MasterPiece controller typically relies on a separate battery backup unit or flash memory for permanent program storage during power cycles.
