Schneider Electric STBDRA3290K Digital Output Kit

Schneider Electric STBDRA3290K is a standard digital output kit for the Modicon STB distributed I/O family, delivering two relay outputs (2 O) that switch loads up to 7 A per channel. Built around the STBDRA3290 module, the kit is designed for 24 V DC control and can switch loads in the 20–250 V AC or 5–30 V DC range, with each channel providing one normally open (NO) and one normally closed (NC) contact for flexible control of actuators, relays, or indicators. Kit contents typically include the STBDRA3290 module, mounting base STBXBA2000, and connection accessories STBXTS1100 (5-terminal screw-type) and STBXTS2110 (5-terminal spring clamp), enabling plug‑and‑play assembly within a Modicon STB system. Protective features include coil protection with a time-lag fuse on the PDM, GMOV surge protection, and insulation ratings that help maintain isolation between channels as well as between the logic bus and actuator bus. The device responds to state changes in roughly 10 ms, supporting fast digital control in automation routines, and is designed for reliability in distributed I/O configurations with a robust mechanical lifecycle. End-of-commercialization notices exist for regional variants, with Schneider Electric listing the STBDRA3290K in some catalogs as discontinued around December 1, 2027, while continuing service and parts through end-of-life. In short, the STBDRA3290K provides a compact, two‑channel relay output solution for Modicon STB systems, combining a dedicated output module with compatible mounting and connection hardware to streamline deployment in industrial control schemes.
