iCenta - Model Tracker 220 Series -Digital Panel Indicators
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
The tracker 220 series of Digital Panel Indicators are highly accurate with communications for temperature and process measurement.
