The Murrelektronik Cube20 is a fieldbus I/O station with modular expandability. It is strictly oriented by the requirements of modern wiring in control cabinets. Due to its compact design Cube20 provides a very high channel density in a small space. This allows placing up to 488 I/Os on just 90 centimeters DIN rail.
All Cube20 modules are equipped with codeable plug terminals for typical control cabinet 1-wire connectivity. Experiences from mechanical engineering show that some control cabinets have up to 100 I/O points or even more. Compared to the complex structure of I/O stations consisting of numerous individual components Cube20 offers the advantage of lower installation costs and does not leave many terminals unused. Moreover, using Cube20 has an impact on inventory and purchasing. It helps to significantly reduce the hidden costs caused by handling various individual components.
Thanks to the expandability of Cube20 with many digital and analog input and output models universal applications are possible. There are different bus nodes available for the connection to a higher-level system, therefore it is possible to exchange buses without changing the system. This is a great advantage for the designer: Customer-specific requirements can be realized in a simple and time-saving way. Cube20 can be operated as stand-alone unit at the fieldbus, and also in combination with Cube67. This allows an even more economic use of existing resources such as Cube67 bus nodes.
Cube20 I/O modules are galvanically separated and have an integrated supply terminal. This simplifies the implementation of different potential groups.
All Cube20 modules are equipped with a continuous, convenient diagnostic system as standard. LEDs light up precisely where the problem is; in addition a message is generated and sent to the control. This simplifies the first startup and allows pinpoint localization of sources of interference. This helps to significantly reduce downtime and increase productivity.
