I/O Modules

Field Control I/O Modules are available in many types to suit a wide range of application

needs. Modules can be installed and removed without disturbing field wiring. One or

two I/O modules may be mounted on an I/O Terminal Block.

I/O Terminal Blocks and Auxiliary I/O Terminal Blocks

An I/O Terminal Block provides mounting, electrical, and field wiring connections.  Each half

of the I/O Terminal Block can be mechanically keyed to accept only an I/O module of a

specific type. Auxiliary I/O Terminal Blocks can be easily attached to an I/O Terminal Block.

They provide the extra connections needed for analog and high-density discrete modules.

Chapter 2: Installation, which explains wiring to the Bus Interface Unit, and explains

how to install the Bus Interface Unit module on the Field Terminal Block.

Chapter 5: Operation, which explains how the Profibus Bus Interface Unit services I/O.

The Field Control I/O Modules User’s Manual, which describes I/O modules and I/O

Terminal Blocks. This manual also explains module installation and field wiring.
