Introduction to Kongsberg RDIOR400
RDIOR400 Product Introduction
Kongsberg RDIOR400 is a high-reliability remote digital input/output (I/O) module, specifically engineered for integration into Kongsberg Maritime automation systems. It serves as a critical interface between the central control system and field devices, enabling efficient transmission of digital signals between the serial process bus (SP Bus) and remote equipment such as valves, relays, and sensors. The module is designed to provide a cost-effective solution for connecting multiple inputs and outputs to Kongsberg automation systems, regardless of the distance between remote equipment and the controller computer. Equipped with dual SP Bus interfaces for optional redundancy and electrical isolation, it ensures stable and secure data transfer even in harsh marine, offshore, and industrial environments. Its rugged construction, combined with built-in line fault detection (LFD), earth fault detection (EFD), and dual watchdog functions, enhances operational reliability and fault identification capabilities.
