ABB S800 Series Analog Input Module AI895 3BSC690086R1, 8 channel, 4-20mA/Hart
The AI895 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 connection to the process devices without additional terminals. TU890 for Ex applications and TU891 for non Ex applications.
