The ABB AI830A is an RTD (Resistance Temperature Detector) analog input module in the S800 I/O system. The details are as follows:

It has 8 channels for connecting resistance temperature detection elements (RTDs), supporting 3-wire connection. All RTDs must be isolated from ground.

It can be used with PT100, Cu10, Ni100, Ni120, or other resistive sensors.

It features a 14-bit resolution, ensuring accurate temperature measurement.

The module can linearize the temperature and convert it into Celsius or Fahrenheit. Each channel can be configured independently: the power frequency filtering cycle time is set via the mainsfreq parameter, and a notch filter can be provided at the specified frequency of 50Hz or 60Hz.

The input channels monitor conditions such as open circuits, short circuits, and sensor grounding, ensuring the reliability and safety of the system operation.

It complies with electrical safety standards including EN 61010-1, UL 61010-1, EN 61010-2-201, and UL 61010-2-201. It can be used in hazardous areas such as Class I, Div 2 (CUS), Class I, Zone 2 (CUS), and ATEX Zone 2.

The current consumption of the +5V module bus is 70mA, and the current consumption of the +24V module bus is 50mA.
