Product description:

Individual, customer-specific solutions and flexible system/plant extensions are requirements that are becoming increasingly important due to digitalization in the process industry. With 16 freely configurable digital IO channels, the SIMATIC CFU DIQ Edition offers a solution for the growing demands for the decentralized peripherals. In addition, the SIMATIC CFU has expansion functions that can be optionally parameterized.
