ABB AO895 – 8-Channel Analog Output Module with HART & Intrinsic Safety

Article Number: 3BSC690087R1
System: S800 I/O

Product Overview

The ABB AO895 is an advanced 8-channel analog output module designed for use in hazardous areas. It includes Intrinsic Safety (IS) protection and supports HART communication on each channel, enabling direct connection to process equipment without the need for additional external isolators or safety barriers.

This module is ideal for applications requiring safe and reliable analog output control, such as driving Ex-certified current-to-pressure (I/P) converters and other field actuators in explosive environments.

Key Features & Benefits

• 8 Analog Output Channels
  Outputs range from 4 to 20 mA for controlling field devices.

• HART Communication Support
  Enables device diagnostics and remote configuration over the same signal line.

• Intrinsic Safety Built-in
  Channels include IS protection components, allowing safe use in hazardous areas.

• Isolated Channel Group
  All 8 output channels are grouped and electrically isolated from the ModuleBus and power supply.

• Integrated Power Conversion
  Converts 24 V input power for output stages—no external conversion hardware required.

• Overload Protection
  Each channel can drive up to 20 mA and is limited to 22 mA in overload conditions.
