ABB-related catalog information identifies 57360001-HG as DSMB 127 Memory Board, RWM with Battery, with a stated memory capacity of 64KB. The same reference gives the replacement battery designation as 4944016-3.
A separate inventory reference also identifies DSMB127 as a 64KB Memory Module and shows variants carrying 57360001-HG/2. That suffix matters when comparing an installed card with replacement stock.
Application Scenarios & Pain Points
Aging memory hardware creates a different maintenance problem from a failed analog input. The system may appear electrically healthy while stored information becomes questionable after power cycling.
- ABB Advant Master: DSMB127 belongs to the Advant Master process-control hardware family and provides RWM memory with battery retention.
- Legacy DCS maintenance: Useful when maintaining an installed Advant Master system where the existing memory board is showing retention problems or has reached an uncertain battery condition.
- Control-data retention: The 64KB RWM provides retained memory rather than serving as a field signal interface.
- Spare-parts inventory: Particularly relevant for plants maintaining older ABB control cabinets where an apparently healthy spare may have been sitting on a shelf for years.
Field note: Battery age is the first thing I would investigate on an old DSMB127. A board that looks perfect—clean edge connector, no burnt components, no corrosion—can still have a battery that has simply aged out.

- ABB DSMB125 — Another memory-module family member. It is useful when maintaining related ABB legacy systems, but its memory architecture and part number must be checked before substitution.
- ABB DSMB144 — A later ABB memory module reference using part number 57360001-EL. It belongs to a different memory implementation and should not be treated as a direct DSMB127 replacement.
- ABB DSMB110C — Another DSMB-series memory module, identified with part number 57330001-NJ. Same broad memory-module category, different hardware identification.
- ABB DSPC153 — A main processor card in the ABB legacy control ecosystem. It performs processing functions rather than serving as the DSMB127 memory board.
- ABB DSPC157 — A memory-board reference carrying 57310001-GP. It is related conceptually but has a different ABB part number and should not be assumed interchangeable.
- ABB DSMC110 — Floppy disk interface card reference within the same older ABB equipment ecosystem. It addresses system data transfer/storage interfaces rather than RWM retention.
- ABB DSBC173 — Bus repeater/interface hardware used in ABB legacy architectures. It supports communication infrastructure, not memory storage.
- ABB spare battery 4944016-3 — The battery reference specifically associated with in ABB catalog information. For an installed , battery replacement should be evaluated as part of preventive maintenance.
The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do not ignore the battery just because the board passes a power-on test.
The uses battery-backed RWM. A board can initialize normally while its retention capability is deteriorating.
How to avoid it: Record battery condition and replacement history. ABB’s reference identifies 4944016-3 as the spare battery associated with this board.
⚠️ Check the suffix carefully.
You may encounter 57360001-HG and 57360001-HG/2 in inventory references. Do not assume that the suffix is irrelevant.
How to avoid it: Photograph the complete label and compare the exact ordering code, revision, and physical board version against the installed unit.
⚠️ Do not replace the memory board without considering retained system data.
A memory-board replacement can have consequences beyond simply restoring hardware. Depending on the Advant Master configuration, stored data and system-specific information may need to be preserved or re-established.
How to avoid it: Before removal, document the existing system state and follow the applicable ABB maintenance procedure. ESD precautions are also mandatory; a clean-looking legacy board can be damaged by a single careless handling event.
Frequently Asked Questions (FAQ)
What is ABB 57360001-HG?
ABB 57360001-HG is a 64KB RWM memory board with battery backup associated with the ABB Advant Master process-control system.
What type of memory does use?
The catalog description identifies the board as RWM, 64KB, with battery retention. It is therefore intended for retained system memory rather than functioning as a conventional field I/O module.
What battery is used with ABB ?
ABB catalog information identifies 4944016-3 as the spare battery reference for the . When purchasing a used board, battery age should be checked rather than assuming the installed battery is still serviceable.
Is the same as 57360001-HG/2?
They refer to the same family, but inventory records show 57360001-HG/2 as a specific variant designation. For a critical replacement, match the complete marking on the installed board rather than relying on the generic name.
Can I replace with another ABB DSMB memory module?
Do not assume direct interchangeability. DSMB-series boards have different part numbers and memory implementations. For example, DSMB144 carries 57360001-EL, while is identified as 57360001-HG.
How should I evaluate a used ?
Ask for photographs showing the complete 57360001-HG identification, board revision, battery area, connectors, and PCB condition. For a critical spare, functional testing should include memory initialization and retention verification—not merely a visual inspection or power-on check.
