Description

SD822 3BSC610038R1: Product Overview
This power supply module is designed for integration into ABB’s S800 I/O system and AC 800M distributed control system (DCS) architectures, serving as a critical component for delivering regulated power to controllers, I/O modules, sensors, and actuators. Its role is to ensure continuous, stable DC power in industrial environments where voltage fluctuations or interruptions could compromise process control.
The core functionality involves converting a wide range of AC or DC input voltages into a precise 24V DC output, with built-in processing for load regulation, transient suppression, and fault detection. It handles standard industrial power inputs (85-264V AC or 210-375V DC) and delivers up to 5A of current (with select models supporting 10A), sufficient for most control cabinet loads. As part of the S800 I/O series, the module benefits from ABB’s modular platform, which emphasizes scalability, interoperability with AC 800M controllers, and compliance with global industrial standards. The platform’s design allows for easy integration with existing systems and supports redundancy, enhancing overall system availability.

Core Features & Customer Value​
Wide input voltage tolerance: The module accepts both AC and DC inputs across broad ranges (85-264V AC, 210-375V DC), allowing it to adapt to unstable grid conditions or legacy power infrastructure. For engineers, this eliminates the need for external voltage converters in regions with fluctuating supply, reducing cabinet complexity and cost.
High-efficiency power conversion: With 94-96% efficiency, the module minimizes energy loss as heat, lowering operational costs and reducing cooling requirements in control cabinets. This is particularly valuable in continuous-process plants where power consumption is a key expense.
Integrated protection mechanisms: Built-in overload, short-circuit, overvoltage, and overtemperature protections safeguard both the module and downstream devices. For the customer, this reduces the risk of component damage during faults, extending equipment lifespan and minimizing unplanned downtime.
Redundancy capability: When paired with ABB’s SS823 or SS832 voting units, the module supports parallel operation for N+1 redundancy. In critical applications like power generation or chemical processing, this ensures uninterrupted power delivery if a primary supply fails, enhancing system reliability.
Compact DIN rail design: The module’s small footprint (123x45x115mm) and DIN rail mounting simplify installation in space-constrained control cabinets. Its IP20 rating protects against dust ingress, making it suitable for most industrial environments without additional enclosures.

Typical Applications​
The module is deployed in scenarios requiring stable DC power for automation systems. In a chemical plant’s distributed control system (DCS), it powers S800 I/O modules and ABB AC 800M controllers, ensuring continuous monitoring of reactor temperatures and valve positions. Its wide input range accommodates voltage sags common in older facility grids.
In a municipal water treatment facility, it supplies power to PLCs controlling pump stations and sensor arrays. The redundancy feature is critical here, as a power failure could disrupt filtration processes, leading to contamination risks.
Another application is in a steel mill’s motor control center (MCC), where it powers variable frequency drive (VFD) logic circuits. The high efficiency reduces heat buildup in the MCC, while overload protection prevents damage to VFDs during motor startup surges.
