SINAMICS G120 Control Unit CU240B-2 B type RS485 interface with USS/MODBUS RTU protocol 4 DI, 1 DO, 1 AI, 1 AO PTC/KTY/Thermoclick Interface USB and SD/MMC interface Degree of protection IP20 Ambient temperature 0 to +50 °C without Power Module Control Unit SINAMICS CU240B-2 Control Unit for basic variable-speed drive applications together with the modular SINAMICS G120 inverter. The CU240B-2 Control Unit is part of the modular SINAMICS G120 inverter (comprising power unit, control unit, operator panel).The control unit is designed for all of the usual applications with U/f or vector control. These include encoderless basic applications in general machinery construction.The CU240B-2 Control Unit controls and monitors the power unit (Power Module) and the connected motor several control modes can be selected. It facilitates communication to a local or central control system as well as to the monitoring equipment – and is used to connect all process-related auxiliary equipment and external components (sensors, valves, contactors, etc.)The I/O interface, the fieldbus interfaces and the additional software functions optimally support its use in general machinery construction.For intuitive series commissioning, a card slot is provided for cloning parameters sets. The communication interface of the inverter is defined when selecting the CU240B-2. The following integrated communication versions are available: CU240B-2 with USS and Modbus RTU protocols and CU240B-2 DP PROFIBUS.The Control Unit can be operated with the following SINAMICS power units: PM240-2 (0.55 kW to 132 kW) and PM240 (up to 250 kW). SINAMICS - simply my drive!
