Product Introduction
The Schneider Electric STBACO0220 is a high-performance standard analog output module designed for use within the Modicon STB (Smart Distributed I/O) system. It is engineered to deliver two high-precision analog output channels, making it an essential component in applications that require accurate and reliable control of actuators, valves, variable speed drives, and more.
Operating in 12-bit resolution, this module is ideal for providing continuous analog signals in the form of current outputs, specifically within the ranges of 4…20 mA or 0…20 mA. The STBACO0220 offers excellent signal fidelity, noise immunity, and rugged field reliability. With integrated diagnostics and status feedback, it ensures smooth operation within distributed architectures.
Its modular, DIN-rail mountable design and plug-and-play compatibility with the Advantys STB system make it a go-to choice for automation professionals seeking efficient, space-saving I/O deployment.
