ABB AI890 Analog Input Module
Overview
The ABB AI890 is an 8-channel analog input module designed for ABB’s S800 I/O system.
It includes Intrinsic Safety (IS) protection on each channel for direct connection to hazardous area field devices.
Each channel can function as a current input or power a two-wire transmitter, ensuring flexibility for various process instrumentation needs.
The module isolates all channels from the ModuleBus and power supply within a single group.
The AI890 supports TU890 and TU891 compact MTUs, allowing two-wire connections without additional terminals.
TU890 is designed for Ex applications, while TU891 suits non-Ex applications.
