Tracker 321  
One Module For Signal Conditioning and Simple Distributed Data Acquisition with RS485 MODBUS

The Tracker 321 provides the following benefits.
  • DIN-Rail Mountable
  • Signal isolation eliminates earth-loops, which can cause noisy, inaccurate measurements.
  • Accurate analog re-transmission of 1 part in 32,000 (15 bit), 4-20 mA, 0-20 mA or 0-10V output.
  • Linearization of thermocouple and RTD sensors so the output is linear to temperature.
  • User configurable linearization for applications such as tank contents measurements.

  • Two wire communications link for simple installation.
  • Will power a two-wire transmitter (24 VDC) or a strain gauge device (10 VDC).
  • RS 485 interface enables wiring runs of up to 1.2 km, allowing distribution to a single channel.
  • Up to 32 RS485 devices can be connected in a multi-drop configuration.
  • MODBUS RTU allows easy integration with industry standard software products
