Schneider Electric STBACO1225 Analog Output Module

Schneider Electric STBACO1225 is a two‑channel analog output module for the Advantys STB distributed I/O family, delivering two isolated 4–20 mA current outputs with 10‑bit resolution. This basic module ships as a kit that includes the STB analog output module plus a base, and its hardened design is built for industrial environments within the Modicon Edge I/O ecosystem. Each channel provides isolation between outputs, helping prevent interference and protecting the control system while driving field devices through standard 4–20 mA loops. The STBACO1225 is documented as the 4–20 mA current output option in Schneider Electric’s Advantys STB catalog, alongside other analog I/O choices, and it integrates with Schneider Electric’s Advantys STB hardware lineage for scalable distributed control. The outputs are isolated to safeguard the controller from electrical faults, and related Advantys STB specifications note short‑circuit protection on the outputs for added reliability in harsh industrial environments.
