Features:
- SD854 Power Supply module 20A
- DCS 800xA I/Os Power Supplies
- Current Sharing Feature for Parallel Use
- Temperature range -25°C and +70°C (derating 12W / °C between 60°C - 70°C)
The SD85x Power supply units are designed for high efficiency, electronic inrush current limitation, wide operating temperature range, and extraordinarily small size. The lowest power losses and high lifetime expectancy deliver the lowest cost of ownership.
The SD85x series complies for use in potentially explosive atmospheres (IECEx Zone 2 and ATEX Zone 2). The SD85x series has a built-in power reserve and can easy breaking fuses due to high overload peak current capability.
The SD854 3BSE088189R1 ABB Power supply module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- System 800xA Power Supply: Serves as the primary 24V DC power supply for the Select I/O and S800 I/O modules in the System 800xA architecture.
- SELV and PELV Loads: Designed for applications requiring Safety Extra Low Voltage (SELV) or Protective Extra Low Voltage (PELV).
- Hazardous and Corrosive Areas: Meets ATEX/IECEx Zone 2 and G3 corrosive environment standards, suitable for locations with frequent exposure to volatile gases or corrosive substances, such as oil, gas, and chemical plants.
- High Load Redundancy: Can be used in parallel with other units for load balancing, or in conjunction with SS823 or SS832 diode voting units for redundant configurations.
- Space Saving: Its compact 48mm width significantly saves rack space compared to dense control panels.
- Easy Circuit Breaking: Capable of delivering high overload peak current (60 Amps, lasting 12 milliseconds), reliably disconnecting secondary circuit breakers during faults.
- Monitoring: Includes DC normalization relay contacts for integrated system monitoring.
