Description
The Kongsberg RMP420 (Part Number 306712) is a versatile Remote Multipurpose I/O (Input/Output) Module designed to serve as a critical data acquisition node within Kongsberg Maritime’s automation systems, such as the K-Chief or K-Bridge platforms. By decentralizing I/O functions, the RMP420 allows for flexible, scalable system architecture, reducing long-run cabling costs while ensuring high-speed, reliable communication between field sensors and the central control system. It is specifically engineered to process a wide array of signals—ranging from temperature and pressure sensors to binary switch statuses—within the challenging, vibration-heavy environments characteristic of modern maritime vessels.

Important Configuration Note: As a multipurpose module, the RMP420 relies on software-defined parameters for each channel. When installing a replacement module, you must ensure the unit is correctly addressed on the fieldbus and that the I/O mapping configuration is pushed to the module via the Engineering Workstation; otherwise, the system will report a “Module Configuration Mismatch” or “I/O Communication Loss.”
