Product Model: ABB SA168
Part Number: 3BSE003389R1
Brand: ABB
Series: SA Smart Analog Signal Converter / Transducer Series
Product Type: Industrial Analog Signal Amplifier / Transducer
Category: Process Signal Conditioning Module
The ABB SA168 3BSE003389R1 is a robust industrial analog signal converter designed for signal conditioning, scaling, and reliable transmission of analog measurement values in automation and control systems. It serves as a scalable amplifier and isolated transducer that converts raw sensor signals into standardized industrial analog outputs suitable for controllers, data acquisition systems, or process control loops.
The SA168 is typically installed in control cabinets or panel racks where it interfaces with field sensors such as thermocouples, resistance temperature detectors (RTDs), pressure transmitters, or other low‑level signal sources. It amplifies, filters, and linearizes these inputs to ensure accurate and noise‑free transmission to downstream devices.
With an emphasis on industrial reliability and precision, the SA168 supports isolated signal paths to prevent electrical interference and ground loop disturbances. Its precise conversion functionality allows operators and controllers to monitor and regulate process parameters accurately for both continuous control and safety interlock logic.
