Turtle Tough’s Family of PLC based Analysers and Controllers provides an unprecedented level of data management and connectivity with modern industrial networks. Driven by a powerful PLC, our factory programmed HMI’s provide a user-friendly interface that allows for easy management of sensors, data, and control systems. The intuitive touchscreen interface allows users to access dozens of sensor parameters, calibration information, diagnostics, event and data logging. The analyser can simultaneously connect with any combination of Turtle Tough’s pH, ORP or DO Direct Smart Sensors (DSS) and seamlessly interfaces with industrial networks utilising the latest industry protocols (MODBUS over Ethernet) providing a highly sophisticated platform for remote monitoring and control.

Multi-Channel touchscreen PLC analyser and controller’s features:

Multi-Channel, Multi-parameter Analyser

Direct Smart Sensors with Digital MODBUS RTU Output (DSS)

Turtle Tough’s range of Direct Smart Sensors (DSS) are equipped with an onboard microprocessor which is capable of processing measurement data and providing a feature-rich digital MODBUS RTU output directly from the sensor. This enables the sensor to be directly interfaced with any MODBUS compatible data acquisition device, such as a PLC, RTU or data logger. Direct connectivity eliminates the need to interface with a traditional intermediary controller or analyser and provides unprecedented communication and control directly with the sensor.

Process more than a dozen parameters with Direct Smart Sensors including:

  • Measurement type
  • Calibration data
  • Raw and calibrated process values
  • Max/min temperature
  • Baud rate
  • Node
  • Serial number

…as well as useful service information such as the number of days in use. These values can be intelligently integrated into your data acquisition system to achieve a sophisticated level of analysis and control. The Turtle Tough family of PLC based Analysers and Controllers automatically acquires this data into a comprehensive suite of functions that allow full sensor management and control. We’ve done the hard work, so you don’t have to.
