Description

Technical Parameters ABB SD822

Product Advantages and Features ABB SD822

1. High efficiency and low energy consumption, cost-saving operation

   ABB SD822 achieves an efficiency of up to 92% at full load, which is significantly higher than the average efficiency of 85% for ordinary industrial power supplies. This high-efficiency design reduces energy loss during power conversion, lowers the operating temperature of the module, and cuts down the long-term energy costs of the automation system, especially suitable for 24/7 continuous operation scenarios.

2. Comprehensive protection mechanisms, safe and reliable operation

   ABB SD822 is equipped with a full set of protection functions including overvoltage, overcurrent, short-circuit, and overheating protection. When an abnormal condition occurs in the system, the module will automatically limit the output or shut down to protect itself and the connected control components (such as PLC CPUs, I/O modules) from damage, minimizing the risk of system downtime caused by power failures.

3. Wide input voltage range, strong adaptability to grid fluctuations

   The module supports a wide input voltage range of 100-240V AC, which can adapt to unstable grid voltage conditions in industrial sites and remote areas. It can maintain stable 24V DC output without manual adjustment, eliminating the need for additional voltage stabilization devices and simplifying the system configuration.

4. Compact design and easy integration, space-saving installation

   ABB SD822 adopts a slim DIN rail mounting structure, which can be easily integrated into dense automation cabinets. Its pluggable terminal design enables quick wiring and disassembly, reducing the time for on-site installation and maintenance. The module also has a compact footprint, making it ideal for retrofitting old control systems with limited space.

Application Cases ABB SD822

1. Automotive assembly line PLC power supply

   In a large automotive factory’s body assembly line project, ABB SD822 is used to supply power to the AC500 PLC system and I/O modules. Its high efficiency reduces the heat generated in the control cabinet, and the comprehensive protection functions prevent power supply failures caused by sudden grid fluctuations or short circuits. The module ensures the stable operation of the assembly line, reducing unplanned downtime by 20%.

2. Chemical plant DCS power supply system

   In a petrochemical plant’s process control project, the module provides stable 24V DC power for the 800xA DCS system. Its wide input voltage range adapts to the grid voltage fluctuations common in chemical plants, and the overheating protection function ensures reliable operation even in the high-temperature environment of the plant’s control room. The module’s long service life also reduces the frequency of component replacement in hazardous areas.

3. Municipal water treatment plant automation control

   In a municipal water treatment plant’s automation project, ABB SD822 powers the PLCs and sensor modules responsible for water quality monitoring and pump control. Its short-circuit protection function prevents damage to the control system caused by water leakage in the field, and the high efficiency helps the plant reduce energy consumption, aligning with the project’s energy-saving and environmental protection goals.

Competitor Comparison

Selection Suggestions

1. For automation systems equipped with ABB AC500 PLCs or 800xA DCS, ABB SD822 is preferred due to its native compatibility and seamless integration capability.
2. If the project requires a high-efficiency power supply to reduce energy costs and heat generation in the control cabinet, this module is a better choice than ordinary industrial power supplies.
3. For industrial sites with unstable grid voltage or harsh operating temperatures, the module’s wide input voltage range and temperature adaptability have obvious advantages over competitors.

Precautions

1. During installation, ensure that the input voltage matches the module’s rated input range to avoid damage caused by overvoltage or undervoltage.
2. When wiring, strictly distinguish between the AC input terminals and DC output terminals to prevent reverse connection, which may lead to module burnout.
3. Regularly check the module’s operating temperature and ventilation status, and ensure that there is no dust accumulation on the surface to maintain good heat dissipation.
4. During maintenance, cut off the input power supply first, and do not touch the output terminals while the module is powered on to prevent electric shock.
