AI845 ABB Analog Input Module

Product Description

The AI845 ABB analog input module converts analog signals into digital signals for use in control systems.

feature

8 channels for 0…20 mA,4…20 mA,0…5 V or 1…5 V d.c.,single ended unipolar inputs

Single or redundant operation

1 set of 8 channels isolated from the ground

12 Bilateral Investment Treaty Resolutions

Current limited transmitter supply for each channel

Advanced onboard diagnostics

Hart Tong Communication

AI845 analog input module for single or redundant applications.The module has 8 channels.When using MTUT844 or TU845,each channel can be a voltage or current input,and when using other MUS,all channels become voltage or current inputs.

The input voltage and current can withstand at least 11 volts of overvoltage or overvoltage.The input voltage resistance is greater than 10M ohms,and the input current resistance is 250 ohms.

The AI845 ABB analog input module allocates external Hart compatible transmitter supply to each channel.This adds a simple connection to allocate the supply to 2-wire or 3-wire transmitters.The transmitter power is monitored and the current is limited.

AI845 is an analog input module that can convert analog signals from sensors,transmitters,etc.into digital signals that can be recognized by the control system.

The AI845 ABB analog input module is compact in design,easy to install,and supports various analog signal inputs such as voltage,current,etc.It adopts advanced conversion technology to ensure the accuracy and stability of the signal.At the same time,it also has various protection functions,such as overvoltage and overcurrent protection,to ensure the safety and reliability of the system.

application area

The AI845 ABB analog input module is widely used in automation control systems in industries such as power,energy,chemicals,and pharmaceuticals.
