ABB 3BSE034741R3122 Analog Input Module
Product Overview
As part of ABB’s S800 I/O Series, this analog input unit is designed to accurately acquire and condition analog signals from field devices and convert them into digital data for use by controllers such as the AC 800M. Its robust design ensures reliable operation in demanding industrial environments.
Main Functions
Signal Acquisition & Conditioning
Receives analog signals (4–20 mA, 0–10 V, thermocouple, thermistor, etc.) from field sensors (temperature, pressure, flow, etc.). Built-in filtering, amplification, and temperature compensation circuits minimize electromagnetic interference and ensure stable, accurate signals.
Seamless System Integration
Communicates with ABB AC 800M controllers or other compatible systems over fieldbuses such as PROFIBUS DP or PROFINET, enabling real-time data transfer for monitoring, trending, and control logic execution.
Status Monitoring & Diagnostics
Built-in self-diagnostics provide operating status information (normal, warning, fault) via LED indicators and system software. Faults such as signal disconnection or power abnormalities can be quickly located by maintenance personnel.
