Product Detail

ABB SS832 3BSC610068R1 Power Voting Unit – 24VDC Redundant Power Solution for 800xA DCS

Product Overview

The ABB SS832 (3BSC610068R1) is a dedicated power voting module designed exclusively for the ABB Advant 800xA distributed control system (DCS). It serves as a critical component in redundant 24VDC power distribution architectures, ensuring uninterrupted, reliable power supply to controllers, I/O modules, safety systems and field instruments in demanding industrial environments.

This DIN-rail mounted unit accepts two independent 24VDC power inputs, performs real-time voltage monitoring and automatic voting, and delivers a single stable 24VDC output (rated 10A). It provides galvanic isolation between input channels, preventing fault propagation and eliminating single points of failure in power supply loops.

Key Features & Benefits

Redundant Power Voting: Seamless automatic switching between two 24VDC inputs; no power interruption during failure, ensuring continuous operation of critical control systems.
High Current Capacity: 10A continuous output per unit; parallel operation of two units supports up to 20A for high-power loads.
Comprehensive Protection: Built-in overcurrent limiting, overvoltage protection (OVP), and thermal monitoring to safeguard both the unit and connected equipment.
Visual & Electrical Status Feedback: Front-panel LED indicators (green for normal, red for fault) plus a dry contact alarm output for remote system monitoring and diagnostics.
Compact & Robust Design: Slim 32mm width for DIN-rail mounting, IP20 protection, G2 environmental compliance, and wide operating temperature range (-25°C to +60°C) for harsh industrial settings.
Easy Integration: Plug-and-play installation, compatible with standard 35mm DIN rails, and fully integrated with ABB 800xA system diagnostics.
