Galvanic Isolated Analog Input Board | ABB AI825 (3BSE036456R1)

Product Description

The AI825 (Part Number: 3BSE036456R1) is a specialized analog input module for the ABB AC 800M controller family, designed for high-precision signal acquisition in demanding industrial environments. Unlike standard input modules, the AI825 (3BSE036456R1) features 4 individually galvanic isolated, bipolar channels. This isolation is critical for eliminating ground loops and ensuring signal integrity when interfacing with sensors that operate at different potential levels.

Each channel on the AI825 (Model: AI825) is highly versatile, capable of being configured for either voltage or current input. The module is built with robust protection circuitry, including a direct current input that withstands up to 6.3 V and an over-voltage protected current input capable of withstanding up to +30 V DC. Current limiting is managed by an integrated PTC resistor, providing a layer of hardware security against field-side faults. Power for the input stages is efficiently converted from the 24 V ModuleBus, ensuring the AI825 (3BSE036456R1) maintains stable performance within the System 800xA architecture.
