ABB AI931S 3KDE175511L9310 Analog Input

The ABB AI931S can be installed in a non-hazardous area or directly in a Zone 1 or Zone 2 hazardous area, depending on the system model selected. The S900 I/O communicates with the control system level using the PROFIBUS DP standard. The I/O system can be installed directly in the field, thus reducing cabling and wiring costs.The AI931S module typically provides 8 or 16 analog input channels, providing flexibility in selecting the number of inputs for connecting various field devices.

The system is robust, fault-tolerant and easy to maintain. Integrated power-off allows replacement during operation, which means that the power supply unit can be replaced by removing the voltage once. AI931S analog input (AI4H-Ex), passive input 0/4...20 mA.
