Product Identification

• Model Number: SD822

• Product ID / Part Number: 3BSC610038R1

• Product Type: Compact Industrial Power Supply Unit

• Product Family: Compact Product Suite / System 800xA Accessory Range

Technical Specifications

• Input Voltage (Nominal): 115 to 230 V AC or 110 to 150 V DC (Accepts wide tolerances: 90 to 264 V AC / 90 to 175 V DC)

• Mains Frequency: 47 to 63 Hz

• Rated Output Voltage: 24 V DC (Adjustable via front potentiometer from 24 to 28 V DC)

• Rated Output Current: 5 A continuous

• Rated Output Power: 120 W

• Efficiency: High efficiency design, typically around 89% to 90% at full load, reducing heat generation inside the cabinet.

• Ripple & Noise: Low ripple output ($<$ 50 mV peak-to-peak), ensuring that sensitive electronic control circuits and analog signals are protected from electrical interference.

• Protection Mechanisms: Built-in protection against short circuits, overloads, and over-voltages (auto-recovery / hiccup mode).

• Supervision Contact: Features an integrated “DC-OK” dry relay contact for remote hardware status monitoring.

• Mounting & Form Factor: Designed for standard 35 mm DIN-rail mounting; slim-line footprint to optimize panel space.

• Dimensions & Weight: Approximately 124 mm (H) x 40 mm (W) x 117 mm (D); Weight is roughly 620 g (1.4 lbs).

Target Industries

The SD822 power supply is built to endure harsh factory floor environments and is standard across infrastructure sectors:

• Automation & Manufacturing: Factory assembly lines, packaging plants, and machine control panels.

• Oil & Gas / Petrochemicals: Deployed inside distribution cabinets at refining, pipeline, and storage facilities.

• Power Utilities: Used within power plant control systems and localized electrical substations.

• Water & Wastewater: Integrated into municipal pumping stations and continuous water treatment facilities.

• Marine & Infrastructure: Certified for maritime applications (such as DNV-GL, ABS, Lloyd’s Register) for use aboard cargo vessels and offshore installations.

Applications and Use Cases

• PLC and Controller Node Powering: Serves as the primary 24 V DC power source for small-to-medium PLC racks, distributed I/O modules, and fieldbus communication couplers.

• Redundant Configuration ($1+1$ or $N+1$): Can be paired with an external voting module (such as the ABB SS822/SS832) to set up a dual redundant power array, ensuring that if one power supply fails, the secondary unit takes over without process disruption.

• Field Instrument Control Loops: Safely drives power to field instruments, 24V sensors (photoelectric, proximity, etc.), small solenoid valves, and indicator lights.

• Cabinet-Level Diagnostic Alerts: The “DC-OK” relay is wired directly back to a central PLC input point, allowing the system to instantly flag a maintenance alarm on the HMI if the panel power drops below operating limits.
