| PID Controller With RS485 MODBUS. |
|
The Tracker 332 provides the following benefits.
|
- DIN-Rail Mountable
- Universal Input for Thermocouples, RTD, mV, Volts and mA
- RS485 Communications, 4 protocols including Modbus RTU
- Fieldbus Connection
- Genuine single loop integrity for critical plant control systems
- Auto Tune PID or On/Off control
- Reverse, Direct and Heat + Cool control actions
- Thermocouple condition monitoring
- Communication loss "self protection" modes
- Partial load and load condition monitoring
- 10V / 24V DC sensor excitation supply
- Universal 90-265V AC supply
- Pulse width modulation (PWM) logic control outputs and partial load plus load condition monitoring functionality is available but requires connection to a Tracker 340 and an external current transmitter.

To use the Tracker 332 as a PID controller, the analog output option and / or the Tracker 340 logic expansion module must be fitted. The Tracker 332 can be provided with 4 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.
