ABB SS822 (3BSC610042R1) – S800 I/O shield/ground management and segment termination accessory

The ABB SS822, part number 3BSC610042R1, sits in the S800 I/O ecosystem and is typically used to tidy up field-cable shielding and segment termination around TU8xx termination units. From my experience, plants add the SS822 when they want clean, repeatable grounding practices on mixed-signal cabinets and to reduce noise coupling into analog or high‑resolution inputs. You might notice that it’s a passive, cabinet-mounted accessory—nothing flashy—yet it solves those everyday wiring headaches that cause intermittent noise and hard-to-trace faults.

Key Features

• Shield/ground organization – Provides a neat, consistent place to terminate cable shields, helping reduce EMI on sensitive I/O in many cases.
• Passive and simple – No external power needed; it integrates alongside TU8xx termination units without changing system design.
• S800 I/O ecosystem fit – Designed to complement AC 800M / 800xA S800 I/O installations for both brownfield and greenfield panels.
• DIN-rail / panel-friendly – Typically cabinet-mounted near the termination units, keeping wiring short and serviceable.
• Noise mitigation in practice – A maintenance lead told us it “cleaned up” two problematic analog loops simply by standardizing shield bonding with the SS822.

Related or Supporting Products

• ABB TU810 / TU812 / TU830 / TU835 – Termination units for S800 I/O; pair with SS822 to standardize shield bonding next to field terminal blocks.
• ABB TB820V2 / TB821 – ModuleBus fiber optic modems; used when extending S800 I/O across cabinets, while SS822 handles local shield/ground organization.
• ABB SB821 – Safety/isolating barrier accessory used in hazardous-area loops; compared with SS822, SB821 addresses intrinsic safety rather than shield termination.
• ABB SS823 – Companion shield/termination accessory variant used in similar panel layouts; selection typically depends on wiring density and cabinet standards.
• ABB AI810 / DI810 series – S800 I/O analog/digital modules that benefit from clean shield practices; the SS822 helps reduce interference on these modules.

Installation & Maintenance

• Cabinet & mounting – Install on a grounded DIN rail in a clean, ventilated cabinet. Keep high‑voltage or high‑frequency drives and their cabling physically separated to limit coupling.
• Shielding practice – Bond cable shields at a single defined point per loop (typically cabinet end) to avoid ground loops. The SS822 provides a tidy, consistent landing for those shields.
• Wiring – Route analog and low-level signal cables away from power lines. Maintain minimum bend radius and use ferrules on multi-strand conductors where required by site standards.
• Ground continuity check – During commissioning, verify shield continuity and cabinet earth bonding with a low-ohm meter. Re-check after major maintenance.
• Routine care – Since the SS822 is passive, maintenance is light: periodic visual inspection, tighten terminals per torque spec, and remove dust. No firmware or calibration needed.
• Environmental range – Aim for 0–55°C operating conditions; if cabinets run hot, add ventilation or spacing, as higher temperatures typically accelerate aging of wiring and plastics.

Quality & Certifications

• CE marked; designed for industrial EMC environments when installed per ABB guidelines
• RoHS compliant materials
• UL/CSA cabinet use (where applicable for the S800 I/O assembly)
• Manufactured under ISO 9001 quality systems
• Manufacturer warranty typically 12 months; our supply warranty is 365 days as stated above

If you’re standardizing panel builds across multiple sites, this little module tends to pay for itself by keeping shield terminations consistent and serviceable. It seems to be one of those “fit-and-forget” pieces that quietly improves signal reliability.
