Description
The AO895 3BSC690087R1 Analog Output Module has 8 channels. The module 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.

FAQ
Q: What is the AO895 3BSC690087R1?
A: It is a Analog Output Module.
Q: Does AO895 3BSC690087R1 support redundancy?
A: No. AO895 3BSC690087R1 is designed for standalone operation (Redundancy: No). If redundant analog output is required, other S800 series redundancy solutions should be considered.
Q: Can AO895 3BSC690087R1 output 0–20 mA?
A: No. To ensure intrinsically safe loop operation and HART communication compatibility, AO895 only supports 4–20 mA output.
Q: What is the difference between AO895 and AO890?
A: AO895 is an upgraded version of AO890, featuring improved HART communication stability and enhanced reliability of internal components.
Q: How to Check Price and Availability for AO895 3BSC690087R1?
A: Please contact John Yang for sales at +86-18150117685 or request a quote.
