ABB SD831The ABB SD831 is a key component of the ABB Ability™ System 800xA® hardware series, belonging to the S800 I/O module family. As a compact switching power supply module, it is specifically designed for industrial automation systems, supporting both non-redundant and redundant applications. Its primary function is to provide a stable 24V DC output for control units (such as AC 800M or AC 800PEC) and I/O devices in ABB automation systems.
ParametersRated output current: 3A (maximum output current: 3.3A)
Rated output voltage: 24V DC
Input voltage range:
AC input: 100–240 VAC
DC input: 110–300 VDC
Efficiency: 88%–89.8%
Ripple: ≤50mV
Peak current: Inrush current at startup <28/54A
Power factor: 0.61/0.56 (AC/DC input)
Power dissipation: 10/8W (at rated power)
Operating temperature: -20℃ to +55℃
Mounting method: DIN rail mounting, with dimensions of 35mm (width) × 102mm (height) × 131mm (depth)Product FeaturesCompact design: Adopts DIN rail mounting to save space, suitable for modular systems.
High reliability:
Equipped with multiple protection functions (overcurrent, overvoltage, undervoltage).
Features soft-start function to avoid triggering fuses or ground fault circuit breakers.
Flexible configuration: Supports non-redundant and redundant applications, suitable for single-point or distributed power supply needs.
Communication compatibility: Integrates with control systems via fieldbuses (such as Profibus DP, EtherNet/IP, Modbus).
Safety standards: Complies with international certifications including IEC 61131-2, UL 508, and EN 50178.Structure and CompositionModular design: As part of the S800 I/O system, the SD831 can work in conjunction with other modules (e.g., I/O modules, power modules).
Mounting methods:
DIN rail mounting: Standard 35mm width, suitable for industrial cabinets or control cabinets.
Backplane mounting: Can be directly installed on the backplane of the S800 I/O system.
Connection terminals: Input terminals (L+, L-, L-) and output terminal (L+), equipped with a power indicator (OK).Application FieldsThe ABB SD831 is widely used in the following industrial scenarios:Industrial automation: Power supply for control systems, I/O modules, sensors, and actuators.
Process control: Power supply for automation systems in chemical plants, water treatment plants, and power generation facilities.
Building automation: Power supply for building lighting, Heating, Ventilation, and Air Conditioning (HVAC), and security systems.
Machine automation: Control and monitoring of production line equipment.
Energy and infrastructure: Power supply for remote I/O systems in fields such as electric power, petrochemicals, and water treatment.Installation and MaintenanceInstallation requirements:
Ambient temperature: -20℃ to +55℃; protection class IP20 (compliant with EN 60529 standard).
Installation depth: 7.5mm; ensure compatibility with DIN rails or backplanes.
Maintenance recommendations:
Regularly check the tightness of connection terminals to avoid poor contact due to looseness.
Monitor input voltage fluctuations to ensure they are within the allowable range (±10%).
Avoid long-term operation in high-temperature or humid environments to extend service life.
