Rockwell Automation offers many types of I/O modules and has more than
3 million modules installed in applications worldwide. Rockwell Automation
offers chassis-based and both block and modular-distributed modules.
The following sections outline the available I/O modules. For more
information about these I/O modules, see the Allen-Bradley I/O Module
Brochure, publication ACIG-BR002, or visit the Rockwell Automation

Modules
If your application requires preferred I/O for PLC-5, and Use this type of I/O On any of these networks
• Native I/O providing highest performance
• Is chassis-based and needs to accommodate a wide range of I/O types
• Controls an entire process
• Is a master/slave configuration for distributed control
1771 I/O
see page 8
- ControlNet
- Remote I/O
- Extended Local I/O
If your application Use this type of I/O On any of these networks
• Is chassis-based and requires different types of I/O
• Has smaller size requirements than 1771
• Communicates with SLC controllers
1746 I/O
see page 13
- ControlNet
- Remote I/O
