Features:
- Legacy industrial memory board module
- Static random access memory (SRAM) and non-volatile memory components (EPROM/EEPROM) are used to store critical system memory
- It is a key component of heavy industrial drive systems and ship propulsion control, and also the basic storage board of the digital reference controller (DRC) in the early PLC framework
The MEM86-3X192 R3R1R3 is a key hardware component in traditional control systems and early large industrial drive systems, such as core drivers, PLCs, or controller platforms used to control high-power synchronous/asynchronous motors. This board employs a dedicated memory architecture; the "3X192" in its model name indicates that it is equipped with three sets of high-speed static random access memory (SRAM), each with a capacity of 192KB, for a total storage capacity of 576KB.
In terms of technical characteristics and system assurance, this module possesses strong anti-interference data error correction capabilities and a long-life condition-maintenance design. Its built-in static RAM employs advanced ECC (Error Correction Code) technology, enabling it to automatically detect and correct single-bit errors in stored data even in industrial environments with severe electromagnetic interference and harmonic effects, thereby preventing control system failures due to data faults. The module integrates clear status indicator lights, providing maintenance personnel with real-time feedback on the memory's power supply and read/write status.
The MEM86-3X192 R3R1R3 ABB Memory Board Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Industrial Control and Drive Systems: This storage module is primarily installed on the main control CPU unit and is responsible for storing system application logic, set parameters, and fault log data (fault waveforms).
Data Power Loss Protection: This type of static random access memory (SRAM) typically relies on a built-in backup battery on the motherboard to retain data after a power outage. If your device experiences errors such as "memory error" or "low battery" leading to data loss, please back up the original control program before replacing this storage board.
Capacity Configuration: The "3X192" designation indicates that this board integrates three independent 192KB traditional memory channels, for a total capacity of 576KB.
Memory Type: Static Random Access Memory (SRAM) is used, supplemented by non-volatile memory components (EPROM/EEPROM) to store critical system firmware, system configuration logic, and active function block parameters.
"R3R1R3" Suffix: This specific alphanumeric code represents different factory hardware versions or pre-loaded firmware configurations. It determines the physical layout and addressing scheme of the memory chips; therefore, when replacing components, it is essential to ensure they are perfectly matched to prevent backplane addressing conflicts.
Hardware Features: This board is equipped with integrated microswitches for manually mapping different I/O addresses and features an onboard 3.6V backup battery (typically a Varta cylindrical battery) to prevent data corruption during power outages.
MEM86-3X192 R3R1R3 is identified by both the memory-board code and its execution marking. Verify the controller generation, slot and retained program before removing the original board.
