Series: AAI841 Analog I/O Module Series
Product Introduction
The AAI841-S00/K4A00 is a high-performance analog input/output module designed for integration in distributed control systems (DCS) and automation environments. It provides a balanced mix of 8 analog input and 8 analog output channels with support for standard 4–20 mA current signals. The module’s S00 variant focuses on cost-effective solutions without HART communication capability but maintains high reliability and accuracy, making it ideal for industrial automation applications requiring stable and straightforward analog signal processing.
The module utilizes the K4A00 terminal block for secure and efficient wiring, simplifying installation and maintenance. Its compact design and robust construction ensure compatibility with a wide variety of industrial control racks and systems.
