ABB AO895 3BSC690087R1 Analog Output IS HART 8 ch
Description:
AO895 is desinged as ABB 800xA control system analog output module. AO895 has 8 channels and includes Intrinsic Safety protection components and a HART interface on each channel for connection to process equipment in hazardous areas without the need for additional external devices.

Each channel can drive up to 20 mA loop current into a field load such as an Ex-certified current-to-pressure converter and is limited to 22 mA in overload conditions. All eight channels are isolated from the ModuleBus and power supply in one group. Power to the output stages is converted from the 24 V on the power supply connections.
