MAQ20 Data Acquisition System Features

Tech Note

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 (Class I, Division 2, Groups A, B, C, D)
  • 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
