Tracker 220 Series

The Tracker 220 series of universal input indicators comprises a range of four models which offer unparalleled price and performance. The use of surface mount components and modern microprocessor technology has enabled powerful features to be packed into a standard 1/8 DIN case. The measurement performance is significantly better than that normally associated with indicators in this price range.

The four models can be used for simple measurement-only applications or in more demanding situations requiring digital communications, alarms, maths functions and complex signal conditioning. The powerful menu-driven software enables fast flexible set-up from the front panel or via the serial communications interface. No adjustments of internal potentiometers, internal links or plug-in cards are necessary.

Features of the T220 Digital Panel Indicators include:

  • Universal input
  • Analogue output
  • Digital status inputs
  • Transmitter & transducer supplies
  • 4 alarm set-points
  • Wide ranging power input
  • IP65 front panel
  • Standard 1/8 DIN size
  • Red or green LED display
  • Programmable function buttons
  • Maths functions
  • Serial communications
