ControlWave I/O Expansion Rack Instruction Manual
The ControlWave I/O Expansion Rack provides additional I/O in a
separately mounted rack for an existing ControlWave process
automation controller.
This manual focuses on the hardware aspects of the ControlWave
Expansion Rack. For information about the software used with the
ControlWave I/O Expansion Rack, refer to the ControlWave I/O
Expansion Rack Quick Setup Guide (D5122), the ControlWave
Designer Programmer's Handbook (D5125), and the online help in
ControlWave Designer.
This chapter details the structure of this manual and provides an
overview of the I/O rack and its components.

The ControlWave I/O expansion rack was designed with an emphasis
on providing high performance with low power consumption,
scalability, and modularity.
You can configure the ControlWave I/O expansion rack as a slave to a
ControlWave Process Automation Controller (CWPAC), ControlWave
Redundant Controller (CWRED), or a ControlWave Redundant I/O
Switch Unit (CWRED I/O). Communication to the rack can be via an
Ethernet connection, serial MODBUS, or Open MODBUS.
 Low power consumption
 Small size (enabling panel mount or 19 inch rack-mount
installations)
 Two or three RS-232 ports
 One or three 10/100 MB Ethernet ports
 Options for additional communication ports
 Housings to support four or eight I/O modules
 Variety of I/O modules and support for hot swapping of I/O modules
 Support for redundant operation with another ControlWave I/O
expansion rack
 LED status indicators on the CPU, PSSM, and certain I/O modules
