Product Introduction
The ABB SD833 is a 24 VDC DIN-rail power supply used in ABB S800 I/O, AC800M controller, and Industrial IT 800xA-related installations. It provides stable DC power to I/O modules, communication interfaces, and controller subsystems where a compact, field-proven ABB power supply is required. With auto-selecting input voltage and 10 A continuous output, it is commonly used in S800 I/O clusters and AC800M power segments.
For redundant 24 VDC architectures, the SD833 can be paired with an ABB SS832 voting unit to maintain supply continuity if one power supply fails. This makes the SD833 a practical spare for plants maintaining S800 I/O racks, AC800M controller racks, or distributed I/O stations where downtime must be minimized.

Key Selling Points & Differentiators
- OEM-identifiable ABB power supply for clean procurement approval.
- Factory-sealed surplus reduces handling risk compared with used pulls.
- 10 A 24 VDC output suits larger S800 I/O clusters and controller power segments.
- Auto-selecting AC/DC input simplifies installation across different site supplies.
- Supports redundant power configuration with SS832 voting unit.
- G2-rated design supports use in more demanding industrial environments.
- Suitable for plants maintaining S800 I/O, AC800M, or 800xA installations.
- Not recommended for unrelated drive, servo, or non-ABB platforms unless the OEM documentation confirms compatibility.
Quality Transparency SOP
- Visual inspection: Check housing, terminal blocks, labels, and SD833 / 3BSC610066R1 marking.
- ESD handling: Anti-static bag, grounded work surface, sealed until installation.
- Terminal verification: Confirm AC/DC input terminals, 24 VDC output terminals, and wiring polarity.
- Compatibility check: Match input voltage range, output current requirement, and rack configuration.
- Documentation review: Confirm part number, revision, lot/serial traceability, and packing condition.
Technical Risk Avoidance
- ❗ Confirm the required output current before ordering. SD833 is rated at 10 A; SD831, SD832, and SD834 provide different current ratings.
- ❗ Verify whether your system requires a standalone DIN-rail power supply or a rack-mounted power module. SD833 is a DIN-rail S800 power supply, not a drive cabinet board.
- ❗ If redundancy is required, confirm whether an SS832 voting unit or equivalent configuration is present.
- ❗ De-energize and follow proper lockout/tagout before removing or installing power supplies.
- ❗ Do not assume SD833 is interchangeable with SD822, SD823, SD831, SD832, or SD834 without verifying rack compatibility and current requirements.
Buyer’s FAQ
- Is this a genuine ABB part?
It is supplied as an ABB SD833 3BSC610066R1 power supply module. Traceability should be confirmed through labeling and packaging before installation. - Is it new or refurbished?
Listed as New Original / New Surplus, factory sealed when available. It is not a repaired or refurbished module. - What does the SD833 do?
It converts 90–132 VAC or 180–264 VAC/DC to 24 VDC and supplies power to ABB S800 I/O, AC800M, or 800xA-related modules. - What is the output current?
The SD833 provides 24 VDC at 10 A continuous output, rated at 240 W. - Can it be used in redundant power systems?
Yes. The SD833 can be used with an SS832 voting unit for redundant 24 VDC supply applications. - Is SD833 the same as SD822 or SD823?
No. SD822 and SD823 belong to a different S800 power supply family with different mechanical and electrical characteristics. SD833 should only be used where the system design confirms compatibility. - What warranty and lead time apply?
Standard 12-month warranty from shipment. Lead time depends on current surplus inventory and revision availability.
