Backplane Bus Communication & Power Retention
The ABB DSSB 140 unit interfaces with the system subrack backplane bus to deliver continuous trickle-charge currents and regulated backup voltage. During primary power interruptions, the unit routes energy from the specified external battery cell to maintain memory retention across CPU cards. High-density contact pins ensure low-resistance connectivity without introducing noise onto deterministic backplane bus communication lines or altering firmware flash compatibility during transient voltage drops.
Frequently Asked Questions
Q: Does the DSSB 140 unit ship with the internal backup battery included?
A: No, the DSSB 140 is a carrier unit that requires one separate battery cell part number 4943013-2 for complete operation.
Q: Can the DSSB 140 battery carrier be replaced or serviced while the main controller is online?
A: Hot-swapping limits depend on system power redundancy; main rack power must remain stable to ensure RAM memory contents are preserved while the battery unit is disconnected.
Field Installation Guidelines
- Verify that the primary rack power supply is active before installing or replacing the backup battery module to prevent memory loss.
- Insert the required battery cell (part number 4943013-2) into the DSSB 140 housing with correct polarity orientation.
- Slide the DSSB 140 housing into the designated subrack guide slot until backplane power connectors fully engage.
- Tighten front panel retention screws to secure physical mounting stability and complete chassis grounding connection.
- Verify cabinet ambient temperature remains within 0 to 55 deg C to maximize backup cell operational life.

Tech & Buying Guide
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
Marshalling Cabinet Preventive Maintenance: Essential Healthiness Checks for PLC, DCS, and ESD Systems
Marshalling cabinets serve as the vital interface between field instrumentation and control room electronics in modern process facilities. Regular preventive maintenance of these cabinets ensures signal integrity across programmable logic controllers (PLCs), distributed control systems (DCS), and emergency shutdown (ESD) networks. System technicians must execute structured inspection protocols to mitigate environmental risks, identify loose wiring, and maintain continuous operational readiness.
Spatial Computing in Industrial Automation: Elevating PLC and DCS Operations with AR and VR
Industry 4.0 integrates digital intelligence into field operations, transforming factory automation landscapes worldwide. Spatial technologies—specifically Augmented Reality (AR) and Virtual Reality (VR)—redefine how engineers interact with industrial control systems. By bridging computer-generated CAD models with real-time operational technology (OT) data, immersive displays enable intuitive monitoring, rapid diagnostics, and safer maintenance across complex processing facilities.
