The AI830/AI830A RTD Input Module has 8 channels for measurement of temperature with resistive elements (RTDs). With 3-wire connections. All the RTDs must be isolated from ground.The AI830/AI830A can be used with Pt100, Cu10, Ni100, Ni120 or resistive sensors. Linearization and conversion of the temperature to Centigrade or Fahrenheit is performed on the module.Every channel can be individually configured. The MainsFreq parameter is used to set mains frequency filter cycle time. This will give a notch filter at the frequency specified (50 Hz or 60 Hz).

ABB AI830A is an analog input module in the ABB Advant 800xA system. It is mainly used for the measurement of thermal resistance temperature sensors (RTDs) and the acquisition and conversion of related analog signals. Common product models are 3BSE040662R1, 3BSE040662R2.It has 8 channels and can connect thermal resistance temperature sensors such as Pt100, Cu10, Ni100, Ni120, etc. It uses a 3-wire connection, and all RTDs must be isolated from the ground.
