Description
CIU 501 Ethernet, Modbus TCP, GRM IP The CIU 501 is a standard interface for data transmission between an industrial Ethernet networks based on Modbus TCP or Grundfos Remote Management system (GRM) and a Grundfos pump or controller. It makes data exchange possible between a Grundfos pump or pumping system and a PLC/ SCADA system or GRM. It features digital and analog IO which lets you connect to external sensors, actuators or for simple start/stop control of pumps. GENIbus communication based on RS45 interface to Grundfos pump or controller. Via a rotary switch you can select between protocols Modbus TCP and GRM IP. The interface module can be installed as a wall-mounted unit and is equipped with a 24-240 VAC/VDC power supply. The CIU unit must not be exposed to direct sunlight.
