　　T9881 Other names:

　　Controller module T9881

　　T9881 analog module

　　Editable controller T9881

　　T9881 ICS Triplex Rockwell I/O basic unit module is a triple modular redundant (TMR) PLC module designed based on Rockwell Automation AADvance system. It provides high availability and fault tolerance for critical applications. The module supports a variety of I/O modules, making it a versatile and scalable solution that is widely used in various industrial automation applications.

　　Main features

　　TMR redundancy: The T9881 module adopts a triple modular redundant design to achieve high availability and fault tolerance. This means that even if one or two modules fail, the system can continue to operate, ensuring the continuity and stability of the production process.

　　Scalable architecture: The module supports a variety of I/O modules, and users can choose appropriate modules for expansion according to actual needs to meet different industrial automation needs.

　　Multiple programming language support: The T9881 module supports multiple programming languages such as ladder diagram, structured text and function block diagram, which is convenient for users to program and debug.

　　Easy-to-use development environment: The module provides drag-and-drop programming function, which simplifies the programming process and improves development efficiency.

　　Built-in diagnostic function: The T9881 module has built-in diagnostic functions for troubleshooting and fault isolation, which can help users quickly locate and solve problems.

　　Technical specifications

　　CPU speed: 100MHz, ensuring fast processing and execution of user programs.

　　Memory: 128MB RAM and 128MB flash memory for storing user programs and data.

　　Number of I/O points: Up to 1024 points, meeting the needs of most industrial automation applications.

　　Communication: Supports multiple communication methods such as Ethernet, serial and USB, which facilitates data exchange with other devices and systems.

　　Size: 100×100×25 mm, compact design for easy installation and deployment.

　　T9881 I/O base unit modules are connected as follows:

　　Connecting to the processor base unit (T9100):

　　Connecting to the right side of the processor base unit (I/O Bus 1)

　　Connecting to the right side of other T9881 I/O base units

　　Connecting to other I/O base units:

　　Connecting to the left side of the processor base unit using the T9310 expansion cable (I/O Bus 2)

　　The expansion cable is also used to connect the right I/O base unit to the left side of other I/O base units

　　Module position numbering:

　　Module positions are numbered from 01 to 24, with 01 being the closest on the left

　　Each module can be uniquely identified by combining the bus number and slot number it is in, for example 1-01

　　Electrical characteristics

　　The electrical characteristics of the I/O bus interface limit the maximum length of two I/O buses (including the I/O base unit and the expansion cable) to 8 meters (26.24 feet).

　　Key Considerations

　　The T9881 I/O base unit modules are part of the ICS Triplex Trusted TMR system.

　　They can be connected to the processor base unit and other I/O base units by direct plug-in.

　　The numbering system of the module position allows precise positioning of each module.

　　Electrical characteristics limit the bus length, which may affect the layout of large systems.

　　Best Practices

　　Consider the bus length limit when designing, and ensure that it does not exceed 8 meters.

　　Using a standardized module numbering system can improve the efficiency of maintenance and troubleshooting.

　　Pay attention to the connection method between the processor and the I/O base unit to ensure the correct topology.

　　When selecting the T9310 expansion cable, ensure that it meets the requirements of the electrical characteristics.

　　Application Scenarios

　　The T9881 ICS Triplex Rockwell I/O base unit module is suitable for various industrial automation applications, such as manufacturing, process control, machine automation and other fields. It can be used as a core component of the control system to realize the control, monitoring and fault diagnosis of equipment.
