data acquisition and control The MAQ20 Data Acquisition System encompasses more than 30 years of design excellence in the process control industry. It is a family of high performance, DIN rail mounted, programmable, multi-channel, industrially rugged signal conditioning I/O and communications modules.


Instrument Class Performance

  • ±0.035% Accuracy, ±0.01% on some modules
  • Industry leading ±0.3°C thermocouple, CJC Accuracy over full operating temperature range
  • Ultra low Zero and Span Tempco
  • Over-range on one channel does not affect other channels
  • 1500Vrms Channel-to-Bus Isolation
  • 240Vrms Continuous Field I/O Protection
  • ANSI/IEEE C37.90.1 Transient Protection
  • Ventilated Communications and I/O Modules
  • Industrial Operating Temperature of -40°C to +85°C
  • Wide Range 7-34VDC Power CE Compliant, UL/CUL Listing and ATEX Compliance pending

Industry Leading Functionality

  • The system is a Modbus Server and can be operated remotely with no local PC
  • Up to 4GB of logged data can be transferred via FTP during real-time acquisition
  • Up to 24 I/O modules, or 384 channels, per system, per 19” rack width
  • Per-channel configurable for range, alarms, and other functions
  • Backbone mounts within DIN rail and distributes power and communications
  • System firmware automatically registers the installation and removal of I/O modules
  • I/O modules can be mounted remotely from the Communications Module
  • Equal load sharing power supply modules allow for system expansion
  • Hot Swappable I/O modules with Field-side pluggable terminal blocks on most models
  • Sophisticated package enables high density mounting in 3U increments
  • DIN Rail can be mounted on a continuous flat panel or plate

Distributed Processing Enables Even More Functionality

  • Output modules are programmable for user-defined waveforms
  • Discrete I/O modules have seven high level functions:
    • Pulse Counter
    • Frequency Counter
    • Waveform Measurement
    • Time Between Events
    • Frequency Generator
    • PWM Generator
    • One-Shot Pulse Generator

Multiple Software Options
