ABB 3BSC610068R1 SS832 24-60VDC 20A NSNP

Technical Parameters:

Input Voltage Range: Supports a wide dual DC input voltage envelope rated from 24 VDC to 60 VDC (operational limits typically span 20 VDC to 72 VDC).

Output Current Rating: Delivers a continuous output current of up to 20A max, making it highly suitable for high-density industrial logic networks.

Redundancy Architecture: Functions as a true diode-based voting / auctioneering module, accepting inputs from two independent, uncoupled power supply units (PSUs) and combining them into a single, fault-tolerant DC output rail.

Internal Voltage Drop: High-efficiency design featuring low forward-voltage drop characteristics across the internal separation diodes, minimizing power dissipation and local heat generation.

Overcurrent Protection: Engineered to safely handle high transient peak currents and short-circuit faults on downstream distribution lines without dropping the alternative power branch.

Galvanic Isolation: Absolute electrical isolation maintained between the two distinct DC input sources to prevent a component short-circuit or failure in one PSU from propagating to or destabilizing the backup PSU.

Diagnostic Feedback Matrix: Features integrated dry relay contacts (Normally Open/Normally Closed signaling) and front-panel LED indicators to provide real-time status monitoring for input power availability and voting network integrity.

Mechanical Design: Compact, ruggedized enclosure layout engineered for secure, vertical DIN-rail mounting inside standard industrial automation marshalling cubicles.

Industrial Sectors:

Process Automation Utilities (Chemical, Petrochemical, Oil & Gas Processing), Conventional and Renewable Power Generation Stations, Water and Wastewater Infrastructure, Mining and Heavy Metallurgical Foundries, and Pulp & Paper Production Lines.

Application Scenarios:

1. Redundant DCS Control Power Supply: Installed within central ABB System 800xA control enclosures to merge two independent 24V or 48V DC power feeds into a single line, guaranteeing uninterrupted power to critical AC 800M processor backplanes.

2. High-Availability Field Instrument Infrastructure: Deployed inside remote marshalling panels to secure the 24V supply loops of hazardous-area field transmitters, preventing data loss or safety shutdowns if a primary power source fails.

3. Emergency Interlock Power Routing: Integrated into critical Emergency Shutdown (ESD) or safety-instrumented system (SIS) cubicles where continuous logic voltage must be maintained to keep safety relays energized.

4. Distributed Power Plant Substation Isolation: Positioned across utility substation control networks to bridge dual-battery DC backup systems, maintaining continuous communication and circuit breaker telemetry even during a severe utility grid blackout.
