The ABB AI815 3BSE052604R1 is an 8-channel analog input unit designed for integration within the ABB S800 I/O architecture. Operating within distributed control environments such as Advant OCS and System 800xA, this module acquires process signals for industrial monitoring and control loops. It features eight independent input channels supporting standard current and voltage ranges, while providing dedicated channel-level power supply features for loop-powered field transmitters.
The unit supports HART communication pass-through, allowing digital diagnostic data and configuration commands to traverse the analog loop without disrupting the primary 4-20 mA measurement signal. All channels are grouped electrically and isolated from earth ground to minimize common-mode interference in electrically noisy plant environments. The AI815 mounts on standard S800 MTUs (Module Termination Units) such as the TU810, TU812, or TU814 series, facilitating clean field wiring termination and straightforward hardware replacement.
