Cube20 is a fieldbus I/O station with modular expandability, which can be integrated along with the Cube67 I/O system. Cube20 is designed for the requirements of modern wiring in control cabinets. High costs from dealing with many individual components are reduced when you use Cube20 thanks to the compact design and a high channel density of 32 channels per I/O module. With 488 channels on 90 cm, Cube20 can easily save space and you get more flexibility. Cube20 features maintenance-free plug terminals for single-wire connectivity that is standard in control cabinets.
