ControlWave ExpressPAC is designed to perform as the ideal platform
for remote site automation, measurement, and data management in
process control and manufacturing. It can serve as a process automaticn
controller or remote terminal unit (RTU). Typical process inputs used
by the ControlWave ExpressPAC are pressure, flow, level, temperature
and frequency input [typically used for positive displacement (PD)],
turbine, or ultrasonic meters. In some cases, inputs may also be derived
from external multivariable transmitters using either the BSAP or
Modbus protocols. Emerson provides the ControlWave ExpressPAC in
a NEMA 3R rated enclosure which allows operation in an un-protected
outdoor environment.
Features ControlWave ExpressPAC has the following key features:
 Exceptional performance and low power consumption through use
of the ARM microprocessor
 Very low power consumption to minimize costs of integrated solar
panel / battery power systems
 Three CPU / System Controller board configurations (see Table 1-
1.)
 Three process I/O board configurations (see Table 1-2.)
 Two RS-232 and one RS-232/RS-485 asynchronous serial
communication ports
 Optional 10/100 MB Ethernet port
 Broad selection of modem and wireless communication options
 Optional display or display/keypad
