Description
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.
