AI815 8-Channel Analog Input Module 0-20mA/0-5V HART S800 | ABB

The Original New ABB AI815 3BSE052604R1 is an 8-channel analog input module for the ABB S800 I/O system, designed for high-precision signal acquisition with integrated HART pass-through communication. It accepts 0-20 mA, 4-20 mA, 0-5 V, or 1-5 V DC single-ended unipolar signals from field transmitters and sensors. The module distributes a HART-compatible transmitter supply to each channel, enabling direct communication with HART-enabled smart field devices without additional hardware. It integrates seamlessly with ABB 800xA DCS, AC 800M, and Freelance controller platforms, providing accurate measurement of temperature, pressure, flow, and level signals in process manufacturing, oil & gas, chemical processing, and power generation facilities.
