ABB 07AI91 Product Overview

ABB 07AI91 is a powerful analog input and output module.Here is a detailed introduction to the module.

Main features

Analog input

The module has 8 analog input channels,which can be configured in pairs for connecting various sensors,such as temperature or voltage sensors.

Pt100,Pt1000 linearization and thermocouple types J,K and S linearization are supported,but only electrically isolated sensors can be used.

Each channel is configured using 16 bits,and the address setting of the module is performed by the DIL switch.

Analog output

The main function of this module is to convert the input digital signal into digital-to-analog and output adjustable continuous voltage,current and signal.

For example,in the TV control block,the analog output module can be used to convert the digital-to-analog conversion to output a continuous voltage signal that changes with the input signal,thereby controlling the volume,brightness and contrast,etc.

Power supply and connection

24V DC power supply is adopted.

The CS31 system bus connection is electrically isolated from the rest of the device,which improves safety and stability.

Diagnostic function

It provides many diagnostic functions and can self-calibrate all channels,further enhancing its reliability.

Application field

ABB 07AI91 analog input and output module is suitable for various application scenarios that require precise analog input and output,such as power plants,chemical plants,steel plants and other industrial fields.It can be used to monitor and control various process parameters such as temperature,pressure,flow,etc.to ensure the stability and safety of the production process.
