Schneider STBXBA3000 Advantys STB I/O Base

STBXBA3000 Extra-Wide I/O Base for STB Relay Modules

Product Introduction

The STBXBA3000 serves as an extra-wide mounting base for Advantys STB high-current relay modules. Schneider Electric designed this base to hold STBDRA relay output modules in place. As a result, it forms the physical foundation of a relay output station. Each base links its module to the backplane and keeps field wiring organized. Furthermore, the 28.1 mm width provides generous space for high-current relay circuitry. This part carries an IP20 protection rating, so it suits clean industrial environments. However, Schneider Electric has discontinued this series and replaced it with the Modicon X80 range. Therefore, the STBXBA3000 mainly serves maintenance and spare parts needs today.

Mechanical and Environmental Parameters

Mechanical fit plays a key role in modular I/O systems. Specifically, the STBXBA3000 locks onto a standard DIN rail and holds one high-current relay module. Its extra-wide body gives relay circuits the space they need for safe heat dissipation. Meanwhile, the lightweight design reduces strain on the rail and cabinet structure. The IP20 rating means the base blocks solid objects larger than 12.5 mm. However, it does not resist water or dust ingress. For this reason, users should install it inside a protected enclosure. Besides, operating and storage temperature data is not available for this discontinued item. Therefore, engineers should follow the original Advantys STB system guidelines during replacement.

Installation Guide

Installing the STBXBA3000 follows a simple, tool-light procedure. First, snap the base onto a 35 mm DIN rail. Next, slide it next to other STB bases until the connectors align. After that, press the base firmly until the latch clicks into place. Then, mount the matching STBDRA relay module onto the base. Moreover, tighten the retaining screws to secure the module. Finally, check the bus connections before applying power. If you replace an old base, mark the wiring first. This step prevents mistakes during reassembly. In addition, keep the workspace free of dust, because the IP20 rating offers limited protection.
