ABB 3BSE034741R3112 Input Channel Card
ABB S800 I/O Series – Analog Input Module
Product Overview
As an essential component of ABB’s S800 I/O Series, this analog input module acquires and conditions analog signals from field instruments and transmits high-quality digital data to upper-level controllers such as the ABB AC 800M. Designed for high accuracy and reliability, it enables real-time monitoring and control of key process variables.
Main Functions
Analog Signal Acquisition
Receives analog signals from field sensors and transmitters (4–20 mA current, 0–10 V voltage, thermocouple, thermistor, etc.).
Signal Conditioning
Built-in filtering, amplification, and temperature compensation minimize electromagnetic interference and ensure stable, accurate signals.
Real-Time Communication
Interfaces with controllers over fieldbus (e.g., PROFIBUS DP) for immediate data upload and process integration.
Self Diagnostics
Reports module status (normal, warning, fault) via front-panel LED indicators to simplify maintenance and fault location.
