Hardware required for network connection:

CIU 900 + CIM 500 + cable 3m
Product number CIU 900: 99448387
Product number CIM 500: 98301408
Product number Cable 3m: 98589048

Note: Large DDA XL pumps require a CIU box (use of E-Box not possible).

The following cable can be used for the databus communication between the DDA dosing pump and a CIU box. Genibus connecting cable, 3 m, M12 (98589048).

CIM/CIU 500 communication interface for easy integration into Profinet-IO networks. Integration into the system is easy via GSDML files and supports the default profile for ‘intelligent pumps’ by PROFIBUS & PROFINET International.
With a rotary switch, you can also change the protocol, e.g. to Modbus TCP.
An integrated webserver allows the Ethernet parameters to be set easily.

The CIU 900 is an external module for integrating the CIM, for wall or top hat rail assembly. These are equipped with an integrated 24 - 240 V AC/DC power supply unit.
