ABB CI801

ABB CI801 is an important communication interface module.The following is a detailed introduction to it:

1.Product Overview

CI801 is a configuration-type communication interface module launched by ABB,also known as the S800 I/O module.It combines the characteristics of distribution and modularity,and can communicate with the parent controller and PLC(programmable logic controller)through the industry-standard fieldbus.

2.Main functions and features

Communication interface:

CI801 connects to the controller through the PROFIBUS-DPV1 fieldbus to achieve data transmission and communication.

Signal processing:

It can perform signal processing operations,including signal collection,conversion and transmission.

Monitoring information acquisition:

Collect various monitoring information for system status monitoring and fault diagnosis.

OSP processing and configuration:

Supports OSP(Output State Protection)processing,which can set the output to a predetermined state when an error is detected.At the same time,CI801 also has a configuration function that can flexibly configure I/O modules.

Hot configuration operation:

Supports hot configuration operation function,that is,configure and change the module without interrupting system operation.

HART transmission:

Supports HART(Highway Addressable Remote Transducer)communication protocol for communication and data exchange with smart sensors.

Isolated power supply:

Contains an isolated power supply to provide a stable power supply for the I/O module.

III.Technical specifications

Power supply:Usually DC24V,with internal DC/DC isolation conversion.

Power consumption:Low,generally less than 10W.

Input/output specifications:May vary depending on the specific model and application scenario,but usually with multiple input and output channels.

Communication protocol:Supports PROFIBUS-DPV1 fieldbus protocol.

Other features:May include high-speed processing,high-precision measurement,real-time clock,super encryption function,etc.
