The ABB AI830 is a versatile 8-channel analog input module designed for the S800 I/O system. It is engineered to handle 0 to 20 mA and 4 to 20 mA signals from field devices such as sensors and transmitters. Each channel is individually configurable and galvanically isolated, ensuring high signal integrity and system reliability. The module also provides power to 2-wire transmitters and supports HART pass-through communication, allowing for advanced device configuration and diagnostics directly from the control system. Its robust design makes it ideal for a wide range of industrial process control applications.
