ABB-3BSE008544R1

ABB 3BSE008544R1 – AI820 4-channel analog input module for industrial control systems

The ABB 3BSE008544R1, also known as the AI820 module, provides four differential analog input channels for bipolar current (-20…+20 mA, 0(4)…20 mA) and voltage (-10…+10 V, 0…10 V) signals. Each channel is galvanically isolated from the ModuleBus (50 V criterion) and offers 14-bit resolution, enabling precise data acquisition for automation and process control applications.

Key features and benefits:
• Four bipolar differential input channels supporting current and voltage ranges. 
• High resolution 14-bit plus sign for precise measurement. 
• Galvanic isolation for each channel ensures signal integrity and system safety. 
• Compact design suitable for mounting in S800/800xA automation raks.

Applications:
• Process industries requiring analog monitoring (temperature, pressure, flow)
• Automation systems needing accurate analog input data
• Machine control panels and advanced PLC/DCS analog I/O expansion
