1-1 Description
The Brooks Model 0254 is a versatile full-featured measurement and
control process instrument, with precision multiple channel capabilities.
The architecture supports a wide range of operating capabilities organized
to meet the requirements of nearly any high-accuracy measurement and
control application.
This system suits applications requiring advanced multiple channel
operation. It provides control services including rate, batch, and
proportional blending.
The system is all digital, based on microcomputer technology. There is no
power switch to be left off, no feature selection switches or jumpers, and
no analog trimming potentiometers.
It employs surface mount technology and incorporates floating-point digital
signal processing arithmetic. Built-in test capabilities enable simple
installation, and extensive self-tests ensures long-term operating reliability.
The rugged package is modular, providing an ideal solution for use in
demanding applications and tough environments. Options are available for
panel mount, rack mount, and desktop.
1-1-1 Architecture
The system is built on the basics of a multiple-port based architecture,
modularly organized, which are combined as channels, able to meet
present and future instrumentation requirements.
Channels provide for value measurements and quantity accumulation, rate
measurements, scalar measurements, supported by value scaling for
process voltage and current process signals. Signal acquisition uses digital
signal processing rejecting ambient noise and interference.
1-1-2 Communication
The communication facilities provide for data acquisition, command, and
control functions, supporting configuration programming and information
gathering.
1-1-3 Process Controls
Totalizer, batch, and proportional blending are readily achieved using the
front panel key controls or serial commands.
