Description
The AI895 3BSC690086R1 Analog Input Module can directly interface 2-wire transmitters and with a particular connection it can also interface 4-wire transmitters without losing the HART capability. The AI895 Analog Input Module has 8 channels. The module includes Intrinsic Safety protection components on each channel for connection to process equipment in hazardous areas without the need for additional external devices. Each channel can power and monitor a two-wire process transmitter and HART communication. The input voltage drop of the current input is typically 3 V, PTC included. The transmitter supply for each channel is able to provide at least 15 V at a 20 mA loop current to power Ex certified process transmitters and is limited to 23 mA in overload conditions.
TU890 and TU891 Compact MTU can be used with this module and it enables two wire connections to the process devices without additional terminals. TU890 for Ex applications and TU891 for non Ex applications.

FAQ
Q: What is the AI895 3BSC690086R1?
A: It is a Analog Input Module.
Q: Can it connect to a 4-wire transmitter?
A: Yes. Although the AI880A is primarily designed for 2-wire transmitters, it can also be connected to 4-wire instruments using specific wiring methods (using an external power supply) while maintaining HART communication functionality.
Q: Is there a redundant model of the AI895 3BSC690086R1?
A: Redundancy is not supported. The AI895 3BSC690086R1 module is designed for non-redundant applications (Redundancy: No). If the system requires redundancy, a redundant module solution from another S800 series must be selected.
Q: How to Check Price and Availability for AI895 3BSC690086R1?
A: Please contact John Yang for sales at +86-18150117685 or request a quote.
