Product Introduction (No Fluff)
This is a passive shield board for ABB Advant OCS / S100 I/O rack assemblies. It installs into a designated slot to establish a stable ground reference and reduce electromagnetic interference coupling between modules on the backplane.
The value is simple: cleaner signals. In mixed-signal racks where analog inputs sit near digital or power modules, a healthy shield board helps suppress noise, crosstalk, and intermittent drift. There is no firmware to load and no configuration to download—install it, verify bonding, and move on.
QA & Testing SOP (Dynamic & Transparent)
Since this is a passive component, testing focuses on mechanical integrity and continuity rather than firmware or channel calibration.
- Incoming inspection — Verify part number 57330001-Y, check for cracked PCB, corrosion, damaged edge connectors, and label consistency.
- Connector inspection — Examine backplane mating contacts for bent pins, oxidation, or burn marks from poor seating.
- Continuity check — Use a multimeter to verify continuity between the shield board ground points and the chassis ground reference. Confirm no open circuits or unexpected resistance.
- Visual fit check — Verify the board slides cleanly into the rack slot without forcing. Bent guides or warped PCBs indicate prior mechanical damage.
- Packing — Place in anti-static packaging with rigid backing to prevent connector damage during transit.
Installation Pitfalls & Guide (Engineer to Engineer)
❗ Slot position matters. Shield boards are not “filler plates.” They belong in specific slots defined by the rack configuration manual. Installing one in the wrong position may leave sensitive modules unshielded or block a slot needed for active I/O.
❗ Check chassis ground first. A shield board only works if the rack itself has a solid ground connection. If the cabinet ground strap is loose or corroded, the board cannot do its job.
❗ Do not confuse with active I/O modules. DSBB110A has no channels, no LEDs, and no configuration parameters. If you are expecting signal processing or diagnostics from this board, you have the wrong part.
❗ Handle by the edges. Even though it is passive, the edge connector is sensitive. Touching contacts with bare fingers can introduce oxidation over time.
Replacement steps
- Pre-install: Confirm the correct slot position from the rack manual and power down the rack if required.
- Removal: Release the retaining mechanism and withdraw the old shield board straight out.
- Install: Align the new board with the slot guides and seat it firmly until it mates fully with the backplane.
- Verification: Confirm mechanical seating, check chassis ground continuity, and restore power to the rack.
Technical FAQ
Is this an OEM genuine ABB part?
We supply new original and new surplus stock depending on availability. If sealed original packaging is required, confirm before ordering.
Does DSBB110A have firmware or need configuration?
No. It is a passive shield board with no firmware, no DIP switches, and no software parameters. Install and verify grounding.
Can I run the rack without this shield board?
The rack may operate, but you lose the intended EMI protection. In electrically noisy environments—near VFDs, motor starters, or welding equipment—removing the shield board can cause analog drift and spurious faults.
What is the warranty?
Warranty depends on condition and stock type. New surplus units typically carry shorter coverage than new original sealed stock. Confirm before purchase.
Is it in stock and ready to ship?
Inventory changes daily. Send the required quantity and destination, and we will confirm availability, lead time, and shipping options.
