The Grundfos fieldbus concept is the ideal solution for complete control of pumps and pump systems. The Communication Interface Module (CIM) and the Communication Interface Unit (CIU) enable data communication via open and interoperable networks.

The Grundfos CIM/CIU communication interfaces offer ease of installation and commissioning, user-friendliness, and great value for money in the long term. All modules are based on standard functional profiles for easy integration into the network and easy understanding of data points.

CIM modules are add-on modules that allow communication with 11 to 22 kW E-pumps and the new Dedicated Controls for wastewater pumps.

The CIU communication interface unit is for products with a GENIbus interface such as small E-pumps, circulation pumps and boosters. CIU units have an integrated 24 to 240 V power supply and are prepared for wall-mounting or DIN-rail mounting.
