AI835 3BSE008520R1 ABB High-performance isolated analog input module AC 800M System 800xA

Product Overview

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)

Technical parameters

Key parameter monitoring for power plants: Generator excitation current, transformer oil temperature, cooling water pressure (high isolation to prevent interference)
Chemical reaction process control: Autoclave temperature (thermocouple), pH value (mV signal), liquid level (4-20 mA) are mixed and connected
Testing and Calibration Laboratory: High-precision data acquisition, supporting simultaneous connection of multiple types of sensors
Metallurgical and steel rolling production line: Synchronous monitoring of roll position (± 10V), hydraulic pressure and motor temperature
Safety-related auxiliary circuit: Although not a SIL module, its high isolation feature is suitable for the acquisition of important non-safety signals

Installation and Usage instructions
Hardware installation
Insert the AI835 into the S800 I/O electronic rack (such as TB840A);
It is interconnected with the CI854A (optical fiber) or CI801 (electrical) communication module through a dedicated connector.
Connect the on-site signal using shielded twisted-pair cables, with the shielding layer grounded at a single point.
Software configuration
Create an instance of the AI835 device in Control Builder M;
Set the signal type (mA/V), range and engineering unit separately for each channel;
Enable disconnection detection, alarm limit values and filter parameters;
Download the configuration to the AC 800M controller.
Debugging and verification
The green LED on the front panel indicates that the module is operating normally.
A red LED flashing indicates channel-level faults (such as sensor disconnection);
View the real-time values and diagnostic status through the System 800xA screen.
