AI835 3BSE008520R1 ABB High-performance isolated analog input module AC 800M System 800xA
ABB AI835 is a high-performance 8-channel analog input module in the AC 800M distributed control system, specifically designed for applications in harsh industrial environments that require extremely high signal accuracy, electrical isolation, and anti-interference capabilities. Each channel is equipped with independent current/voltage input capability and complete electrical isolation between channels (up to 1500 V AC), effectively preventing ground loops, common-mode interference and equipment damage risks.
Core features
Multi-signal type support (each channel can be independently configured) :
Current input: 0-20 mA, 4-20 mA (active/passive
Voltage input: 0-10V, 0-5V, ± 10V, 1-5V
Automatically identify or set the signal type through software
Full-channel independent isolation
Inter-channel and channel-to-ground isolation voltage: 1500 V AC (1 minute)
Eliminate grounding loops to enhance the stability and safety of the system
High precision and high resolution
Accuracy: ±0.05% of span (typical value, 25°C)
Resolution: 16-bit ADC
Sampling rate: 10 Hz per channel (configurable)
