In its basic form the Tracker 321 is a data acquisition "front end" with a universal input, sensor / loop excitation outputs and serial RS485 interface.

The measured value, after scaling to engineering units, linearisation (e.g. for thermocouple measurement) and any other mathematical functions required, is available via the electrically isolated serial interface.

For signal conditioning the analogue output option is fitted. The conditioned measured value is constantly re-transmitted as an electrically isolated, scaled analogue signal.

A logic expansion module provides 2 configurable logic inputs and up to 4 relays or TTL outputs.

Key Features:

  • Low cost
  • Universal input for mA, mV, V, thermocouples and RTDs
  • 10V and 24V sensor excitation

Please see the TECHNICAL, DOWNLOADS and VIDEOS sections above for more information.
