Product details

Description

Overview

Product Description:
The AO895 Analog Output Module is designed for providing 8 channels of 4...20 mA analog outputs. It features intrinsic safety protection components and a HART interface on each channel, allowing 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. The module’s output stages are powered from the 24 V power supply connections, with all channels isolated from the ModuleBus and power supply in one group.

Features and Benefits:

  • 8 channels of 4...20 mA outputs.
  • HART communication capability.
  • Groupwise isolation of 8 channels from ground.
  • Capable of driving Ex certified I/P actuators.
