Schneider STBAVI1270 Analog Input Module 2-Channel

Schneider STBAVI1270 Advantys STB Analog Input Module

Product Introduction

The STBAVI1270 belongs to the Schneider Electric Advantys STB distributed I/O platform. This standard analog input module provides two single-ended channels for ±10V voltage signals. Furthermore, it delivers 11-bit plus sign resolution, making it suitable for precise industrial measurement tasks. The module supports hot swapping, so technicians can replace it without shutting down the system. Meanwhile, 1500V DC isolation between field and bus protects connected equipment from electrical interference. Because the product is discontinued and superseded by the Modicon X80 range, buyers should verify availability before ordering.

Technical Specifications

The STBAVI1270 module offers two single-ended input channels. Specifically, each channel accepts a ±10V voltage signal with a range of ±10V. The resolution reaches 11 bits plus sign, which supports fine signal discrimination. Additionally, input impedance measures 400 kΩ, and the module tolerates up to 50V DC without damage. Response time is 5 ms for both channels, while the update time reaches 10 ms for two channels. Integral linearity is ±0.2% FS typical, and accuracy is ±0.5% FS at 25°C. Moreover, temperature drift stays at ±0.01% FS/°C. Isolation includes 1500V DC field-to-bus and 30V DC channel-to-channel. Hot swapping is supported.

Electrical and Mechanical Parameters

The module receives 24V DC supply voltage through a PDM. Bus current consumption is 60 mA at 5V DC. The STBAVI1270 fits an STBXBA1000 I/O base with a 13.9 mm width. Besides, the compatible PDM is the STBPDT3100 (24V DC). The protection rating is IP20, so the module suits cabinet-mounted installations. Operating and storage temperature data are not available from the manufacturer. Therefore, users should confirm thermal limits with Schneider Electric or test under actual conditions.

Installation Guide

First, mount the STBXBA1000 base onto the DIN rail. Next, connect the STBPDT3100 PDM to supply 24V DC power. Then, wire the ±10V field signals to the two single-ended input channels. After that, insert the STBAVI1270 module into the base. Because hot swapping is supported, you can install or remove the module while the system runs. However, always follow local electrical codes and plant safety procedures. Finally, configure the module in the Advantys configuration software and verify readings.
