RDIO420S
REMOTE DIGITAL INPUT/OUTPUT MODULE
PART: 316564
REV: 1.1.1
The Kongsberg RDIO420S is a Remote Digital Input/Output Module designed to extend and distribute digital signal handling within marine control and automation systems. As a core component in distributed I/O architectures, it enables reliable communication between field devices and central control processors, supporting real-time monitoring and command execution across critical onboard systems. This module falls within the Marine Control System category and is integral to maintaining accurate, responsive automation performance at sea.
Key Features
✓ Functions as a remote digital I/O node, managing multiple input and output signal channels to support distributed control architectures typical in marine automation environments.
✓ Specific voltage ratings, channel counts, and response times are subject to confirmation based on system configuration — consult technical documentation or contact support for exact parameters.
✓ Designed for compatibility with Kongsberg control system platforms; integration with specific panels, controllers, or network topologies should be verified against the vessel’s system configuration.
✓ Intended for installation in controlled onboard environments; mounting location, enclosure requirements, and environmental ratings depend on the installation context and applicable classification standards.
✓ Direct replacement module for systems running revision 1.1.1 firmware or hardware — verify revision compatibility before installation to ensure seamless system continuity.
Marine Applications
✓ Integrated into Kongsberg-based automation and control systems aboard offshore vessels, platform supply vessels, and offshore support units requiring distributed I/O management.
✓ Used in machinery control rooms and integrated bridge systems where digital signal distribution between sensors, actuators, and control processors is essential.
✓ Applied in dynamic positioning systems and vessel management systems where reliable real-time digital I/O is critical to safe operation.
✓ Deployed in cargo handling, ballast control, and power management automation loops requiring remote digital signal acquisition and output control.
✓ Suitable for naval, research, and commercial vessels operating Kongsberg distributed control architectures that demand modular, maintainable I/O infrastructure.
