NConnect RTU Unit

nConnect®  is a simple control device for pump controlling. It controls smaller waste water pump stations, potable water and raw water pump stations, and suits applications that does not need control based on more advanced functions or remote control. The device includes input and output for level transmitters, power coils for power masurement on connected pumps, operating and alarm signals, serial RS485 for communication on private lines. nConnect is configured via Connect Link™, connect locally using the USB port or via external communication RS485 to e.g. a Mµ Connect®, this type of connection can also be used to transfer data to a SCADA system.


Advantages Using NConnect

  • Pump control including monitoring via pump-word function
  • Input terminals for power coils for meauring power on pumps
  • Logical functions
  • Connection options to e.g. HMI Display
  • Budget friendly slave device for Mµ Connect


The optional build-in Wi-Fi module will provide an easy accessible overview of the operational status of the pump station, as well as simple configurational options such as start/stop levels, history and alarms, by using the MJK APP for smartphones. Communicating on longer distances is assisted by the RS 485 Repeater, that will enhance and correct the signals that travels more than 300 meters.
