Schneider STBACO8220 HART Analog Output Module

Schneider STBACO8220 2-Channel HART Analog Output Module

Product Introduction

The STBACO8220 belongs to the Advantys STB distributed I/O platform by Schneider Electric. This standard analog output module provides two independently isolated channels for 4-20 mA signals with HART communication. Engineers select it for advanced process control tasks that require digital configuration alongside analog output. Meanwhile, the module supports hot swapping, so you can replace it without stopping the whole system. Its compact 13.9 mm I/O base saves valuable cabinet space.

Technical Specifications

The STBACO8220 offers two output channels with a 4-20 mA current range plus HART protocol support. Resolution reaches 15 bits plus sign, which gives exceptionally smooth and accurate signal output. Accuracy stays at ±0.3% FS at 25 °C, while integral linearity is ±0.05% FS and monotonic. Temperature drift is only ±0.005% FS/°C, ensuring stable performance across changing conditions. Update time is just 8 ms, enabling responsive control loop behavior. Furthermore, short circuit protection is built in to guard against wiring faults.

Isolation and Electrical Data

Each channel provides independent isolation, which prevents cross-channel interference. Isolation between field and bus reaches 1500V DC. This rating protects sensitive control circuits from electrical noise. The module draws power through a 24V DC PDM, specifically the STBPDT3100. Additionally, the I/O base is the STBXBA1000 with a 13.9 mm width. This narrow design allows dense mounting in control panels.

HART Communication Benefits

HART support lets you configure and calibrate connected field devices remotely. Therefore, commissioning time drops significantly, and maintenance costs fall. Besides, the digital signal travels alongside the analog current without disrupting the primary process value.

Mechanical and Environmental Parameters

The module carries an IP20 protection rating, which suits clean cabinet installations. Operating and storage temperature data are not available in the current documentation. Besides, the 13.9 mm base width keeps panel space usage low. Field wiring connects through the STBXBA1000 base, and the PDM feeds power separately.

Installation Guide

First, mount the STBXBA1000 base onto a standard DIN rail. Next, snap the STBACO8220 module onto the base until it locks firmly. Then connect the 24V DC PDM, such as the STBPDT3100, to supply field power. After that, wire your 4-20 mA HART loads to the output terminals while observing polarity. Finally, configure the HART parameters through your Advantys STB network configuration tool. Always verify wiring polarity for proper 4-20 mA and HART operation.
