| The Tracker 300 series is a low cost multifunctional signal conditioner, trip amplifier and PID Controller with RS485 MODBUS RTU communications. |
|
 |
| The Tracker 331 provides the following benefits. |
- DIN-Rail Mountable
- Universal Input for Thermocouples, RTD, mV, Volts and mA
- RS485 Communications, 4 protocols including Modbus RTU
- Genuine single loop integrity for critical plant control systems
- Auto Tune PID or On/Off control
- One Relay and one SSR output (can be for alarms or PID control)
- Reverse, Direct and Heat + Cool control actions
- Pulse Width Modulation (PWM) logic control outputs
- Partial load and load condition monitoring (requires an external current transmitter for PWM logic control outputs)
- Communication loss "self protection" modes
- Thermocouple condition monitoring
- Universal 90-265V AC supply

The Tracker 331 can be provided with 6 logic outputs using the Tracker 340 logic expansion module. These outputs can be used for PID control or alarm purposes. This expansion module also offers special functions, which can be activated from an external volt free contact or a TTL interface.
These functions include:
- Auto / Manual
- Integral Hold
- PID 1 / PID 2 selection switching between two setpoints, each with its own PID settings.
