TRACKER 300
The Tracker 300 series
The Tracker 300 series is a low cost Signal Conditioner, Trip
Amplifier and PID Controller, for use in a variety of process
applications. Its small size enables high packing density on
standard TS35 DIN rail. A built in power supply, transmitter
excitation and serial RS485 interface provides genuine single loop
integrity with distributed data acquisition and control.
FEATURES
Universal 20 bit input provides accurate measurement of a wide
range of sensors
Real time data available via the isolated RS485 serial interface
Fully configurable by PC software no internal links or potentiometers
Signal Conditioning
The isolation provided in the Tracker 300 series eliminates earth loops, which can cause noisy,
inaccurate measurements. Any Tracker 320 or 330 module can be fitted with an isolated analogue
output for signal re-transmission.
Accurate analogue re-transmission of 1 part in 32,000 (15bit)
4-20mA, 0-20mA or 0-10VDC output.
Linearisation of thermocouple and RTD sensors, so the output is
linear to temperature
User configurable linearisation for applications such as tank
contents measurements.

Distributed Data Acquisition
Often the largest expense of a data acquisition system is the wiring. The Tracker 300
uses a simple two-wire communications link greatly reducing wiring costs and
simplifying installation.
Will power a two-wire transmitter (24VDC) or a strain gauge device (10VDC)
Enables wiring runs of up to 1.2 km on RS485 interface, allows distribution to a
single channel
MODBUS RTU communications protocol allows easy integration with industry
standard software

THE DEFINITIVE SOLUTION
PID Control
The Tracker 331 & 332 models are fully featured auto tuning PID
controllers providing genuine single loop integrity to plant
control systems.
Auto-tune for automatic setting of the PID values; reverse or
direct acting
"Self defence" feature ensures safe operation of the process
should there be a loss of communication for longer than a
pre-set period
Can use pulse width modulated SSR / relay logic or analogue
outputs
Condition Monitoring
Plant shut downs can be time consuming and expensive. The
Tracker 300 series allows the user to plan more effective
maintenance by monitoring thermocouple ageing and the health
of electrical loads.
Alarms when thermocouple shows signs of deterioration
Checks for partial electrical load failure, overloads and open
loads (PWM control only)
Indicates which components should be replaced during
scheduled maintenance
Flexible Alarm Trips
The Tracker 300 series can be used as a trip amplifier by using the dual
relays on the Tracker 331 or by adding a Tracker 340 Logic Expansion
Module to any module in the series.
The use of on and off delay timers and hysteresis functions stops
nuisance or "fleeting" alarms
An alarm can operate more than one output, allowing different
circuit voltages to be switched
Alarm actions can be high, low or deviation;
latching or non-latching; standard or fail safe
operation
Alarm Blocking feature for startup conditions
Logic Expansion
The Tracker 340 Logic Expansion Module provides additional logic inputs and outputs for monitoring and control
applications. All logic states can be read via the communications interface. Logic inputs can also be configured to
perform a number of functions i.e. zero, tare, reset max/min.
Four C/O relay or TTL outputs and two logic inputs
Six front panel LED's indicate the input and output states
Plugs into and is powered by a Tracker 320 or 330
