ABB AO890 Analog Output Module
Overview
The ABB AO890 is an 8-channel analog output module designed for ABB’s S800 I/O system.
Each channel integrates Intrinsic Safety (IS) protection, allowing direct connection to hazardous area field devices without external barriers.
The module supports 0–20 mA and 4–20 mA output signals, suitable for Ex-certified actuators like current-to-pressure converters.
The AO890 is compatible with TU890 (Ex applications) and TU891 (non-Ex applications) compact MTUs, enabling two-wire connections without additional terminals.
