Backplane Bus Communication & I/O Density Scaling
The ABB DSSR 170 power supply module steps down 24 VDC input power to deliver a stabilized 5 VDC, 10 A logic supply directly across the backplane bus. Maintaining regulated power rails prevents voltage drop issues during high-density I/O card population. Integrated backplane interfaces ensure firmware flash compatibility and status reporting across host controller diagnostics.
Frequently Asked Questions
Q: What primary voltage conversion does the DSSR 170 unit perform?
A: The DSSR 170 accepts a 24 VDC input supply and converts it to a regulated 5 VDC output at up to 10 A to energize backplane logic components.
Q: Can the DSSR 170 power supply module be extracted while primary DC power is applied?
A: Main 24 VDC input power must be switched off prior to inserting or removing the unit to prevent arc discharge across backplane connectors and logic corruption.
Field Installation Guidelines
- Isolate primary 24 VDC power before inserting the DSSR 170 power supply module into the chassis rack.
- Align module guides with the subrack rails and slide in until the rear power plug engages completely with the backplane.
- Fasten faceplate locking screws to ensure solid chassis grounding and structural stability under operational vibration.
- Verify that the internal 5 A protection fuse (56722011-21) is seated correctly before energizing the module.
- Ensure adequate convection air flow above and below the module assembly inside the enclosure.

Tech & Buying Guide
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.
Master Acceptance Testing: Understanding FAT and SAT in Industrial Control Systems
Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) serve as critical quality assurance gateways in complex industrial control systems. Both procedures verify that programmable logic controllers (PLCs), distributed control systems (DCS), and associated field devices meet strict functional specifications. However, executing these tests effectively requires clear delineation between off-site staging and final field commissioning.
Industrial Networking Essentials: Demystifying Hubs, Switches, and Routers in Control Systems
Industrial automation relies heavily on robust networking infrastructure to connect programmable logic controllers (PLCs), distributed control systems (DCS), and human-machine interfaces (HMIs). Modern factory automation environments generate vast amounts of real-time operational data across deterministic networks. Understanding the structural differences between hubs, switches, and routers ensures optimal traffic segmentation, minimizes latency, and maintains high network availability.
