Schneider STBAVO1250 Analog Output Module

Schneider STBAVO1250 Advantys STB Analog Output Module

Product Introduction

The STBAVO1250 belongs to the Schneider Electric Advantys STB distributed I/O platform. This standard analog output module provides two single-ended channels for voltage control signals. Furthermore, it supports both 0-10V and ±10V ranges, which users select during configuration. The module delivers 12-bit resolution in 0-10V mode and 11-bit plus sign resolution in ±10V mode. Additionally, 1500V DC isolation between field and bus protects connected equipment from electrical noise. Because the product is discontinued and superseded by the Modicon X80 range, buyers should verify availability before ordering.

Technical Specifications

The STBAVO1250 module offers two single-ended output channels. Specifically, each channel drives 0-10V or ±10V voltage signals into a load. Maximum output current reaches 5 mA per channel, and short circuit protection is built in. Response time is 3 ms plus settling time, while settling reaches 900 µs to ±0.1% of final value. Update time is 25 ms for two channels. Integral linearity is ±0.1% 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. The fallback state defaults to 0V and can be configured for hold last value or a user-specified value.

Electrical and Mechanical Parameters

The module receives 24V DC supply voltage through a PDM. Bus current consumption is 80 mA at 5V DC. The STBAVO1250 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 analog voltage outputs to the two single-ended channels. After that, insert the STBAVO1250 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 each channel range and fallback mode in the Advantys configuration software.
