This manual focuses on the hardware aspects of the ControlWave Process Automation Controller (called the “ControlWave” throughout the rest of this manual). For information about the software used with the ControlWave, refer to the ControlWave Quick Setup Guide (D5084), 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 ControlWave and its components.

ControlWave products have been designed and integrated as a highly adaptable, high performance distributed open controller family with exceptional networking capability that provides a complete process automation management solution for the natural gas, water, and wastewater industries. The ControlWave was designed with an emphasis on providing high performance with low power consumption, scalability, and modularity.
Features ControlWave process automation controllers have the following key
features:
 Low power consumption
 Wide operating temperature range: (–40 to +70C) (–40 to 158F)
 Small size (enabling panel mount or 19 inch rack-mount installations)
 Two RS-232 ports
 One 10/100 MB Ethernet port
 Optional secondary communication board (SCB) provides additional options for RS-232, RS-485, and Ethernet communications
 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 process automation controller
 LED status indicators on the CPU, PSSM, and certain I/O modules Port 80 display to present status codes

 Battery backup for the real-time clock and the system’s static RAM (SRAM)
 Class I, Division 2 Hazardous Location approvals

Each ControlWave has a printed circuit board (PCB) backplane mounted in a stainless steel housing, a Power Supply/Sequencer Module (PSSM), a CPU module which may include an optional Secondary Communication Board (SCB) and—depending on the backplane and housing size—up to eight I/O modules.
