The SD853 3BSE088188R1 is a high-performance DIN rail DC power supply module from ABB. It belongs to ABB's System 800xA automation system platform and is the core power supply component for the S800 I/O module and its matching controller.
High Redundancy Reliability
Industrial-Grade Electrical Stability
Seamless Integration with 800xA
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, ATEX Zone 2, and Class I Div 2). The SD85x series has a built-in power reserve and can easy breaking fuses due to high overload peak current capability.

When using the SD853 (3BSE088188R1) power supply module, the primary considerations are the correct configuration of redundancy and the maintenance of the cooling environment. First, to achieve redundant power supply, the module must be used in conjunction with an SS823 or SS832 voting unit; direct paralleling of the outputs is strictly prohibited. It is also recommended to ensure independent input power sources for both modules to maximize reliability. Second, as the module generates heat during operation, sufficient ventilation clearance (typically at least 50mm above and below) must be maintained on the DIN rail, and dust should be cleaned regularly to prevent triggering thermal protection. Additionally, you should periodically monitor the output voltage to ensure it remains stable at 24V and check for any loose terminal wiring to avoid the risk of localized overheating or system power loss caused by poor contact.
It is a Power Supply Module from the S800 I/O system manufactured by ABB.
How to use products like the SD853 3BSE088188R1?
It is mounted on a standard DIN rail, usually located in the power distribution layer of a control cabinet. Input power is connected via terminal blocks, and the output terminals provide power to AC 800M controllers, S800 I/O modules, or field instruments.
Does the SD853 3BSE088188R1 support redundant configuration?
Yes. This is one of its primary design advantages. Two SD853 modules can be connected via a voting unit (such as SS823 or SS832) to achieve 1+1 redundancy. If one module fails, the other takes over the power supply seamlessly.
What do the LED indicators on the SD853 3BSE088188R1 represent?
The LEDs on the front panel display the power status. A Green light (OK) indicates the output voltage is normal; if the light is off or changes color, it indicates an input power loss, internal fault, or output short circuit.
What are the primary industries for the SD853 3BSE088188R1?
It is widely used in process industries requiring high-reliability control, such as petrochemicals, power monitoring, pulp and paper, pharmaceuticals, and water treatment within automation systems.
