AI830A AI835 AI845 AI880-1 ABB New original analog terminal unit

The AI830/AI830A RTD InputModule has 8 channels for measurement of temperaturewith resistive elements (RTDs). With 3- wire connections. Allthe RTDs must be isolated fromground. The AI830/AI830A can be usedwith Pt100, Cu10, Ni100, Ni120 or resistive sensors. Linearization and conversion of the temperature to Centigrade or Fahrenheitis performed on the module. Every channel can be individually configured. TheMainsFreq parameter is used to set mains frequencyfilter cycle time. This will give a notch filter atthe frequency specified (50 Hz or 60 Hz).

Features and benefits 8 channels for RTD (Pt100, Cu10, Ni100 and Ni120 and resistor) inputs 3-wire connection to RTDs 14 Bitresolution Inputs are monitored for open-circuit, shortcircuit and has a input grounded sensor
