Description
CIU 901 interface unit with I& O | The CIU 901 is a standard interface unit with integrated I& O board and with internal power supply for Grundfos products that do not support the internal add-on modules, to connect via GENIbus to a CIM interface. The CIU 901 can support CIM 200, CIM 260, CIM 280 and CIM 500 interfaces for Modbus and GiC/GRM communication. The built-in multi-purpose I/O board enables monitoring of standard pumps, sensors, meters and switches via: 2x Configurable digital input (open circuit voltage 5 VDC) / analog input ( 0-10V/ 0-20mA/ 4-20mA )2x Digital input (open circuit voltage 5 VDC)1x Pt100/Pt1000 input1x Analog output ( 0-10V , Maximum output current: 1 mA) 1x Relay output ( 240 VAC, 2 A ) The CIU 901 unit is equipped with a 24-240V VAC/VDC internal power supply and can be installed as a wall-mounted unit or on a DIN rail. There is no CIM (Communications Interface Module) mounted inside the CIU 900. Integrated LED for power indication. Clamps for power supply 24-230 VAC/DC 50/60Hz. Clamps for Grundfos GENIbus (RS 485). Socket to mount a Grundfos CIM interface.
