MY Connect® RTU Unit

Mµ Connect® (pronounced ‘My Connect’) is an integrated control and monitoring Instrument. It is designed for the control of pumping stations, small wastewater treatment plants and to measure and record over flow, control filters, raw water pumps and booster pumps for water supply pump stations. Mµ Connect® has advanced features for power optimization of pumps with the control of frequency and has functions for calculation, data logging and communication with SCADA systems.Mµ Connect® has WIFI built-in and is operated with a PC program Instrument Link and can be monitored and updated with a smart phone with graphic and flexible access to data and controls.


Advantages Using Connect

  • Pre-programmed functions and menus
  • Communication options
  • Network options
  • Energy saving
  • Versatile telemetric solution
  • Capable data logger
  • RTU - Remote Terminal Unit



Mµ Connect can be operated from several different devices:

• A smart phone connected through the built-in WIFI. The Apps for both iPhone and Android are free and can be downloaded on the App Store (iPhone) and Android Market. Scan the QR code and download from the App Store or Android Market.

• Connect Link for setup, configuring and online data view through USB, GSM/GPRS modem or WIFI.

• HMI touchscreen display provides easy access to pump control, data readout and real-time operating overview. 


Additional I/O Modules

Mµ Connect can be configured with a wide selection of I/O modules - from a single controller/alerter to a fully expanded multivariable process controller system.The maximum number of I/O modules is 8 units which
combined with the CPU unit give a total maximum of 32 DI, 32 DO, 16 AI and 16 AO. More details in datasheet 6.07
