ABB AI830A 3BSE040662R1 RTD Input Module with 8 channels
Description:
AI830A is designed as ABB 800xA control system Analog Input. 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.  AI830/AI830A can be used with TU810, TU812, TU814, TU830, TU833.

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).
