Overview

Essential details：AI895 3BSC690089R1 Analog Input Module

Product Description

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.

Features and benefits

• 8 channels for 4…20 mA, single ended unipolar inputs.

• HART communication.

• 1 group of 8 channels isolated from ground.

• Power and monitor for Ex certified two-wire transmitters.

• Non energy-storing analog inputs for externally powered sources.

AI895 3BSC690089R1 Analog Input Module

The analog input module is a device that collects the analog signal from the remote field to the computer. It uses the RS-485 bus as a data communication line and provides the analog to 485 function, which can input the analog signal to the module at the same time and transmit it to the computer through the RS-485 bus. As the RS-485 interface is used as the communication interface, it can combine multiple modules to transmit more analog signals, and can be distributed on the 485 line, using the address code to distinguish, and can directly access the configuration software of MODBUS RTU protocol.
