Description

The AO890 is an 8-channel analog output module designed for use in hazardous areas, featuring intrinsic safety protection on each channel. It can drive up to 20 mA loop current into field loads like Ex-certified current-to-pressure converters, with a limit of 22 mA in overload conditions. The module supports two-wire connections to process devices without additional terminals and is compatible with TU890 (Ex applications) and TU891 (non-Ex applications).
