CONFIGURATION SCADA
SOFTWARE SOFTWARE
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.
All Tracker 220 series indicators have been tested and comply with the European Electromagnetic Compatibility
directives and safety requirements. The instruments are designed to be used in the most demanding applications and
each carries the CE marking. The enclosure is manufactured in re-cyclable and flame-retardant (VO) materials and
the front panel conforms to IP 65.
