ABB AI820

ABB AI820 is a differential analog input module.Here is a detailed introduction to the product:

I.Product Overview

ABB AI820 module has 4 channels for a variety of current and voltage input ranges,such as-20~+20mA,0~20mA,4~20mA,-10~+10V,0~10V,2~10V,-5~+5V,0~5V,1~5V d.c.,etc.These channels can be either voltage input or current input,and all 4 channels are isolated from a set of module buses.

II.Main Features

Differential bipolar input:The AI820 module has 4 differential bipolar current/voltage input terminals,which can provide high-precision measurements.

High resolution:The module has 14-bit resolution plus sign to ensure the accuracy of measurements.

Input protection:To protect the current input circuit from dangerous input levels,the AI820 module is equipped with a 250Ωcurrent detection resistor and provides input shunt resistor protection with a DC voltage of 30V.

Module bus power supply:The power supply of the input stage is converted from the 24V voltage on the module bus,which simplifies the power connection.

Multiple MTU options:Four different types of MTUs(module terminal units)can be used,such as TU830 extended MTU,TU810(or TU814)compact MTU,etc.,to meet different application requirements.

Overvoltage/undervoltage protection:The AI820 module has overvoltage/undervoltage protection function,which can protect the module from voltage fluctuations to a certain extent.
