ABB SD823 3BSC610039R1 – Comprehensive Technical Overview and Product Guide
1. Basic Product Information
Product Model: ABB SD823
Part Number: 3BSC610039R1
Brand: ABB
Series: SD Digital Signal Conditioning & Processor Modules
Product Type: Digital Signal Conditioner / Converter
Category: Industrial Signal Processing and Measurement Interface
The ABB SD823 is a high‑precision digital signal conditioning and conversion unit designed to process analog field sensor data into reliable, digitally conditioned signals for industrial automation systems, programmable logic controllers (PLCs), distributed control systems (DCS), and data acquisition hardware.
2. Product Introduction
The ABB SD823 3BSC610039R1 is an advanced digital signal conditioning module engineered for demanding industrial environments where accurate analog‑to‑digital conversion is essential. It accepts raw analog inputs from field sensors—such as current loops, voltage outputs, thermocouples, and resistance temperature detectors (RTDs)—and performs digital filtering, high‑resolution conversion, sensor linearization, and scaling. The conditioned digital signals are then provided in a format optimized for modern programmable controllers, supervisory systems, and data processing units.
With built‑in galvanic isolation between inputs and outputs, the SD823 ensures signal integrity even in electrically noisy environments. Digital filtering reduces interference and improves measurement stability, which is critical for accurate process control and monitoring. The module is designed for 24/7 continuous operation and fits into industrial control cabinets or racks using standard DIN‑rail or rack mount hardware. Its construction emphasizes reliability, precision, and compatibility with a broad range of industrial sensor types.
The SD823 integrates with industrial automation frameworks by delivering conditioned signals that enhance the performance and accuracy of control loops, data acquisition channels, and monitoring displays. Its digital signal processing capabilities make it suitable for applications requiring advanced measurement fidelity.
