DIQ/S 284 - Controller for the IQ SENSOR NET
Digital system to monitor wastewater treatment plants, with up to 4 sensors
Controller for small and mid-sized wastewater treatment plants including USB-interface and internal data logger– up to 4 sensors, all parameters, available anytime:
The new controller DIQ/S 284 is available with different output signals. Besides the reagent-free measurement of COD, all other parameters needed for a wastewater treatment plant can be measured. By the combination of multi-parameter sensors, up to 20 parameters can be measured and displayed simultaneously.
All versions include an USB-interface and an internal data logger by default. Thereby, your valuable data and system configurations can be stored quickly and easily. Stay up-to-date with our free of charge software updates and improve your controller for upcoming measurement tasks. Via the connection to the internet you can access your IQ SENSOR NET anytime and anywhere. Monitoring and support from remote saves time, money and nerves. Via the RS 485- and Ethernet- interfaces, the fieldbuses PROFIBUS, Modbus RTU, Ethernet/IP, Modbus TCP and PROFINET are available. The DIQ/S 284 is compatible with almost all currently available components of the IQ SENSOR NET.
