Product Model: ABB SC540
Part Number: 3BSE006096R1
Brand: ABB
Series: SC Signal Conditioning & Converter Family
Product Type: Industrial Analog Signal Converter / Conditioner
Category: Signal Processing and Measurement Module
The ABB SC540 is a precision industrial signal conditioning and conversion module used to process and standardize analog signals from field sensors for reliable use in automation and control systems.
The ABB SC540 3BSE006096R1 is engineered for industrial environments where accurate signal conditioning, scaling, isolation, and conversion are essential. This module receives raw electrical signals from field‑mounted sensors such as voltage sources, current loops, thermocouples, and resistance temperature detectors (RTDs), then processes these signals to produce standardized analog outputs like 4–20 mA or 0–10 V.
Signal conditioning involves filtering noise, stabilizing the input signal, linearizing non‑linear sensor responses, and providing galvanic isolation to ensure that electrical noise and ground loops do not affect downstream control systems. The SC540 module is designed to operate continuously in industrial automation installations, offering stability and reliability across a wide range of conditions.
The module’s compact DIN‑rail form factor simplifies integration into control cabinets and automation racks. Its screw terminal connections support efficient field wiring and maintenance. The SC540 plays a key role in delivering accurate, noise‑free analog signals to PLCs, DCS, data acquisition systems, and monitoring equipment.
