1.0 Product Introduction
1.1 The System
The 990x is a versatile full-featured measurement and control instrument - with precision multiple port and
channel capabilities. Its operating control primarily supports point-n-click navigation.
It supports an optional mix of up to eight independent full function input measurement ports and advanced
technology output ports. Extensive local and remote information communication is provided.
Superior technology is combined with operating simplicity, versatility and ruggedness. Easy to install -
and easy to operate. An extensive open architecture enables a wide range of special operating
capabilities organized to meet the needs of nearly any high-accuracy precision measure, process, alarm
monitoring and communication application requirements.
1.2 The Technology
The system is all digital based on microcomputer technology - no power switch to be left off, no feature
selection switches or jumpers, no analog trimming potentiometers. Just all digital.
It employs surface mount technology and incorporates a powerful package of floating-point digital signal
processing arithmetic. Built-in test capabilities enable simple installation, and extensive self-tests insures
long term operating reliability. The rugged package is modular - and represents an ideal solution for use
in demanding applications and tough environments. Mounting options are available for rack-panel, desk-
top with support for various input and output signal types.
1.3 The Applications
This system suits applications requiring advanced multiple port and channel, supported by extensive
integrated information communication capabilities. It services nearly all process and sensor signal
measurements for manufacturing and batch processing, proportional blending, machine control, bio-
medical pressure and temperature, chemical and pharmaceutical, laboratory, ecologic, agriculture,
petroleum, heating and air conditioning, water filtration and purification, beverage and fluid delivery,
automatic billing systems, asset accounting and service programs, performance tracking and verification,
quality assurance programs, operations and maintenance management information gathering, regulatory
compliance, liability mitigation, and public safety programs.
1.4 The Organization
The system has port based architecture, modularly organized as independent ports, or ports combined as
channels, to meet present and future instrumentation requirements.
The systems ports support universal input and output signal types. Ports may be intermixed to support an
extremely wide variety of signal service requirements.
Input ports provide value measurements for quantity accumulation, rate measurements, scalar
measurements, supported by value scaling for process frequency, pulse, voltage, current or resistance
signals.
Independent value scaling and smoothing filters compensate for specific signal service requirements.
Signal acquisition uses digital signal processing to reject ambient noise and interference. Programmable
excitation selections are available to power most sensors. Advanced signal output ports provide
extremely stable voltages, currents, and supports isolated relay contacts.
