The SD833 (part number 3BSC610066R1) is a high-performance power supply module from ABB, specifically designed to provide reliable DC power to the S800 I/O system, a critical part of the ABB industrial control portfolio. The SD833 ensures stable operation of I/O modules and connected field devices, making it a crucial component for industrial automation systems.

Technical Specifications and Features

The SD833 module operates with a redundant DC power input, accepting a voltage range of 19.2 to 28.8 V. It converts this input to a stable 24 V DC output, powering the I/O bus and the connected modules. Integrated protection features, such as over-voltage and short-circuit protection, ensure system safety. With a compact design and a net weight of only 0.25 kg, the SD833 is an ideal solution for space-constrained cabinet installations.
