2.Product Features

Multi-channel design:ABB AI890 usually has multiple channels(such as 8 channels)and can connect and monitor multiple analog signals at the same time.

Intrinsic safety protection:The module includes intrinsic safety protection components on each channel for connection to process equipment in hazardous areas without the need for additional external devices.

Current input and monitoring:Each channel can be a current input or power supply and monitors a two-wire process transmitter.The input voltage drop of the current input is usually 3V,including PTC.The transmitter power supply for each channel can provide at least 15V voltage at a loop current of 20mA to power Ex-certified process transmitters,and is limited to 23mA under overload conditions.

Module bus and power supply isolation:All channels are isolated from a set of module buses and power supplies,ensuring signal stability and security.

Easy to expand and configure:ABB AI890 modules support seamless integration with other ABB products,allowing users to expand and configure according to actual needs.

High reliability:The use of high-quality materials and manufacturing processes ensures the stable operation of the module in harsh industrial environments.
