Data Track Tracker 221 - 1/8 DIN Digital Panel Meter
The Tracker 221 is a universal input indicator with 4 digit display which offers unparalleled price and performance 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 powerful menu-driven software enables fast flexible set-up from the front panel or via the serial communications interface.
The Tracker 221 series can be directly connected to most process sensors including thermocouples, RTDs (4-wire), 20mA loops, transmitters, or dc type signals. All thermosensor ranges have built-in linearisation curves and internal or external CJC is available. The display can show °C, °F or Kelvin (Absolute), with the decimal point position being user-adjustable to give the required measurement resolution or switched to automatic (auto ranging mode). Process inputs can be scaled to any engineering unit and any input can be mapped to one of the thermosensor linearisation curves.
Transducer / Transmitter Excitation Supplies
The Tracker 221 digital panel meter includes an isolated 24V DC transmitter supply as standard to provide power for 2-wire (4-20mA) sensors. Also provided is a regulated 10V DC output for strain gauge type sensors such as pressure transducers and load cells.
The Tracker 221 has four software alarms. These can be configured by the user for alarm type, setpoint, on/off delay and on/off hysteresis value. Alarms can be individually set to be latching or non-latching and to flash a message on the front panel display when active.
The Tracker 221 has isolated two wire RS485 serial communications, which is compatible with most SCADA software packages. All measured values and set-up parameters are accessible, however, the instruments can be set to be read only, thus protecting their configuration. Two protocols are available; MODBUS and proprietary DTPI.
