Murrelektronik's Cube family is a modular fieldbus system for machine and plant installations. Cube20S is the newest member of the Cube family and connects slim input and output modules with a width of only 12.9mm for base modules with integrated bus nodes.

Digital and analogue modules with two, four or eight channels are available, as well as function modules such as counters or potential distributors. Combining the standard output modules with Murrelektronik's safety relay MIRO Safe+ makes it possible to safely switch off non-safe outputs up to Category 3 PLd. Modules for active safety applications up to SIL3 and PLe are being planned.

The fieldbus stations can be configured according to requirements, and most common fieldbus systems -Profibus, DeviceNet, CANopen, Profinet, Ethernet IP, Ethercat, and Modbus - are catered for. An interface for Cube67 system is also coming soon. This wide variety of models and the short response times (up to 20µs) make Cube20S suitable for a large number of applications.

Each bus node can be expanded with maximum 64 modules with minimum wiring. Installation is simple and wiring errors are avoided: the modules are connected via a special plug mechanism and they are also protected from reverse polarity. Power and data are supplied via an integrated backplane bus (48Mbit/s) that is integrated into the base. When it's time for maintenance, the electronic modules can be conveniently exchanged without having to be disconnected.

The bases feature a special locking system for DIN rail mounting which makes it possible to assemble the complete station outside the control cabinet and then mount it in as a finished block. With the colour-coded power modules, it is easy to create different power circuits or to refresh the power on the backplane bus.

Cube20S features labels and a user-friendly diagnostic concept: Labels can be attached next to the LEDs. This makes it possible to identify and read channel states reliably. Spring clamp terminals simplify installation.
