DCS Backup Power Solution – ABB DSSB146 | Advant OCS Series
Where This Product Is Used
The ABB DSSB146 Battery Module is a dedicated backup power component engineered for continuous-process industries where an unplanned control system shutdown carries significant operational and safety risk. It is deployed in the following environments:
- Oil & Gas Refineries – Sustains DCS controller memory and I/O communication during grid disturbances, preventing uncontrolled process shutdowns on critical separation and compression trains.
- Chemical & Petrochemical Plants – Maintains live setpoints and alarm states in reactor control loops during momentary power interruptions, enabling safe hold or graceful shutdown sequences.
- Pulp & Paper Mills – Protects Advant OCS master controllers from data loss during power fluctuations common in high-load paper machine drives.
- Power Generation & Utilities – Provides ride-through capability for turbine governor and boiler management systems during switchgear transfer events.
- Water & Wastewater Treatment – Keeps SCADA-linked Advant OCS nodes operational during utility supply interruptions at remote pump stations.
- Pharmaceutical Manufacturing – Supports 21 CFR Part 11 data integrity requirements by preventing mid-batch controller resets that would invalidate batch records.

Application-Specific FAQ
- Q: Can the DSSB146 be replaced while the Advant OCS controller is powered?
- A: Hot-swap capability depends on the specific Master controller model and firmware revision. For AC110/AC160 controllers, a controlled power-down is recommended. Contact us to confirm your configuration.
- Q: How long does the DSSB146 retain memory after a power loss?
- A: Retention time depends on battery age and ambient temperature. A new or freshly tested unit typically provides >72 hours of SRAM retention at 25 °C. We recommend scheduled replacement every 3–5 years as part of preventive maintenance.
- Q: Is DSSB146 compatible with ABB Advant Controller 400 series?
- A: The DSSB146 is specified for the Advant OCS Master Series. AC400 series uses a different battery module family. Contact Konmask.com to identify the correct part for your AC400 installation.
- Q: Do you provide a warranty?
- A: Yes. All tested refurbished units carry a 90-day functional warranty. New surplus units carry a 180-day warranty. Terms available at checkout or on request.
- Q: Can you supply a certificate of conformance (CoC)?
- A: Yes. A Konmask.com CoC is included with every shipment. Third-party inspection reports are available for orders >5 units at additional cost.
