Schneider STBXBA2000 Advantys STB I/O Base

STBXBA2000 Wide I/O Base for STB Analog Modules

Product Introduction

The STBXBA2000 acts as a wide mounting base for Advantys STB analog and AC I/O modules. Schneider Electric built this base to hold STBDAI input modules, STBDAO output modules, and STBDRC modules in place. As a result, it forms the physical backbone of an analog I/O station. Each base links its module to the backplane and keeps field wiring tidy. Furthermore, the 18.4 mm width provides extra room for analog signal circuitry. This part carries an IP20 protection rating, so it fits clean industrial environments. However, Schneider Electric has discontinued this series and replaced it with the Modicon X80 range. Therefore, the STBXBA2000 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 STBXBA2000 locks onto a standard DIN rail and holds one analog or AC I/O module. Its wider body gives analog circuits the space they need for accurate signal handling. 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 STBXBA2000 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 STBDAI, STBDAO or STBDRC 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.
