Schneider STBACI1230 Analog Current Input Module

Schneider STBACI1230 Advantys STB Analog Input Module

Product Introduction

The STBACI1230 belongs to the Schneider Electric Advantys STB distributed I/O platform. This standard analog input module provides two single-ended channels for 0-20mA current signals. Furthermore, it remains compatible with 4-20mA transmitters, which makes it flexible for many field devices. The module delivers 12-bit resolution without a sign bit, so it suits unipolar measurement tasks. Additionally, 1500V AC 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 Because the product is discontinued and superseded by the Modicon X80 range, buyers should verify availability before ordering.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 STBACI1230 module offers two single-ended input channels. Specifically, each channel accepts a 0-20mA current signal and works with 4-20mA devices. The resolution reaches 12 bits, which supports fine signal discrimination. Additionally, the module tolerates up to 25 mA and 50V DC without damage. Each channel supplies 100 mA to field devices and includes electronic short-circuit protection. Response time is 5 ms for both channels, while the update time reaches 10 ms for two channels. A single low-pass filter operates at 25 Hz nominal. 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 AC 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 100 mA at 5V DC. The STBACI1230 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 0-20mA field signals to the two single-ended input channels. After that, insert the STBACI1230 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.
