The ABB AI815 (3BSE052604R1) is an 8-channel analog input module designed for the S800 I/O system. This module is engineered to support HART (Highway Addressable Remote Transducer) pass-through communication, allowing for advanced diagnostics and configuration of field devices. It provides flexible input options, supporting current (0...20 mA, 4...20 mA) or voltage (0...5 V, 1...5 V) signals, though these signal types cannot be mixed on a single module.

The AI815 is an S800 I/O analog input module used to interface field sensors with ABB control systems, supporting both standard analog signals and HART communication.
No, the module must be configured for either voltage or current inputs; mixing signal types on the same module is not supported.
Yes, it features a current-limited transmitter supply per channel, which simplifies the connection of 2-wire or 3-wire HART-compatible transmitters.
