  • Altitude: Capable of operation up to 2000 meters above sea level without derating.
  • Humidity: Withstands 5% to 95% relative humidity, non-condensing, ensuring resilience in tropical climates.
  • Hardware Profile Lockdown: The ABB PS24-EX-SA910S Power Supply Module utilizes fixed, stable hardware-level operational firmware (HW: 12255701M), removing vulnerabilities related to over-the-air firmware hacks or sudden code corruption.
  • DCS Integration Compatibility: Embedded parameters map seamlessly to ABB's system engineering architectures (like Advant OCS or 800xA) via standard GSD file configurations.
  • Diagnostic Code Architecture: Hardcoded hardware states allow the internal controllers to immediately output real-time voltage tracking anomalies to the central S900 gateway interface.
  • Simplified Hardware Lifecycle Management: No software licensing updates or ongoing flash patches are required, dramatically lowering long-term maintenance costs.
  • Petrochemical and Hydrocarbon Refining: Placed directly into distributed control environments to fuel sensors, valves, and intrinsically safe actuators located near hazardous distillation columns.
  • Offshore Oil Rigs & Marine Vessels: Chosen for its high resistance to corrosive saline mist and mechanical vibrations, powering critical remote S900 telemetry racks on drilling platforms.
  • Chemical Processing Facilities: Manages discrete safety loops and continuous analog monitoring lines within designated explosive zone areas.
  • Municipal Gas Distribution Networks: Safeguards the transmission system by supplying spark-free power across localized valve control stations and remote monitoring hubs.
Description
Explosion-Proof Certified for Harsh Environments: The ABB PS24-EX-SA910S carries the ATEX II 2 G EEx m[ib] e IIC T4 certification, allowing it to be mounted directly in Zone 1 explosive gas atmospheres without the need for an additional heavy enclosure. This reduces cabinet space and installation complexity for offshore platforms and chemical plants.

High-Density Power Distribution: Capable of supplying up to 45W of continuous power, the ABB PS24-EX-SA910S can drive up to 16 I/O modules (e.g., AI, AO, DI, DO) plus two CI920S communication interfaces simultaneously. This high-density design minimizes the footprint of your control system in space-constrained skids.

Fault-Tolerant & Hot-Swappable Design: To ensure 24/7 process uptime, the ABB PS24-EX-SA910S supports true hot-swap functionality. In redundant configurations, a failed unit can be replaced without powering down the system or interrupting backplane communications, ensuring bumpless transfer.

Seamless S900 Integration: The ABB PS24-EX-SA910S is specifically tailored for the ABB S900 I/O architecture. It provides electrical isolation and power conditioning via the backplane, requiring only a simple three-step mechanical installation, which significantly reduces Mean Time To Repair (MTTR).

Technical notes
The ABB PS24-EX-SA910S has reached its lifecycle transition and is being replaced by the SA920S; users should note that the ABB PS24-EX-SA910S and SA920S must not be mixed in the same redundant pair due to incompatible load-sharing algorithms. For installations where the primary supply line exceeds 3 meters in length or when a UPS is used, the ABB PS24-EX-SA910S requires the external BP901S power conditioner to suppress voltage transients and high-frequency interference. Additionally, the ABB PS24-EX-SA910S achieves earth reference directly through the DIN rail mounting, eliminating the need for a separate floating ground terminal.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the exact backplane power budget for the ABB PS24-EX-SA910S when powering mixed I/O types?
The ABB PS24-EX-SA910S provides a total power budget of < 45W to the backplane. This is sufficient to power up to 16 standard I/O modules (e.g., AI, AO) or a combination of 14 I/O modules plus 2 x CI920S Profibus communication interfaces, provided each module does not exceed its individual thermal rating.
Can the ABB PS24-EX-SA910S be integrated with a third-party controller via Profibus, or must it be paired with an ABB controller?
The ABB PS24-EX-SA910S supplies power only; communication is handled by the CI920S module. Yes, the S900 I/O system (powered by the SA910S) is communication-agnostic and can be integrated with any Profibus DP master, including Siemens S7 or Emerson DeltaV.
Are there specific firmware dependencies for the ABB PS24-EX-SA910S when used in a redundant configuration?
Yes. For redundant operation of the ABB PS24-EX-SA910S, both units must have identical hardware revision levels. Furthermore, ABB explicitly warns not to mix SA910S with its successor SA920S in a redundant pair, as the load-sharing algorithms are incompatible.
Is the ABB PS24-EX-SA910S approved for SIL 2/3 loops under IEC 61508?
The ABB PS24-EX-SA910S is designed for use in safety instrumented systems up to SIL 3 when used in conjunction with certified S900 I/O modules. While the PS24-EX itself is the power source, its redundant configuration and high MTBF support the overall safety availability.
