AO895 3BSC690087R1 ABB S800 I/O modules Digital I O Module 2.5 / 22.4mA
The AO895 Analog Output Module has 8 channels. The module includes Intrinsic Safety protection components and 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.
Features and benefits
• 8 channels of 4…20 mA outputs.
• HART communication.
• 1 group of 8 channels isolated from ground.
• Power to drive Ex certified I/P actuators.
