Memory Module | DSMB116 5736 0001-EB | ABB

Technical Specifications

The ABB DSMB116 5736 0001-EB is a non-volatile memory module for ABB industrial automation systems, providing reliable storage for control programs and configuration data. DSMB116 5736 0001-EB features a 64 KB non-volatile memory capacity, ensuring that critical information is retained even after power interruptions. The module operates from a stable 5 V DC supply with a maximum current consumption of ≤20 mA and a typical power consumption of ≤0.1 W, delivering efficient performance while minimizing energy consumption in continuous industrial operation.

Troubleshooting & Commissioning Checklist

Cell Storage Checks: Confirm the main chassis emergency backup cell is operational and retaining voltage to safeguard stored info on transient memory sectors.
Track Condition Scrutiny: Examine the multi-ply board edge contact tabs for gouges, tarnishing, or peeling metal foil.
Frame Power Verification: Check that the 5V DC and 24V DC rear-plane voltage feeds remain within spec limits and are totally shut down ahead of plugging in the card.

Field Engineering Considerations

No Hot-Swapping: Turn off subrack power completely before inserting or pulling the board to prevent voltage arcing damage.
ESD Control Protocols: Fasten a grounded anti-static wrist strap before handling the card to protect sensitive memory arrays.
Voltage Rail Verification: Test that the backplane 5V DC logic line operates with under 50mV ripple voltage to stop parity errors.
Inductive Isolation: Route high-power motor or valve control lines away from the memory subrack to minimize magnetic interference.

Technical FAQ

Q: Is it safe to extract or insert the DSMB116 5736 0001-EB card while the subrack power is turned on?
A: No, hot-swapping is strictly forbidden. The subrack power must be fully switched off before handling to prevent severe voltage arcing across the parallel bus.

Q: How does the DSMB116 5736 0001-EB module retain its stored application data when the main cabinet power is cut?
A: It relies entirely on the subrack's centralized backup battery system to supply continuous low-voltage power to the volatile memory chips.

Q: What should field engineers verify first if the CPU fails to recognize a newly installed DSMB116 5736 0001-EB memory board?
A: Check the physical on-board address allocation jumpers to ensure they match the system memory map and do not conflict with existing hardware modules.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
