KONGSBERG
RDIOR420
REMOTE DIGITAL INPUT/OUTPUT AND RELAY MODULE
PART: 306713
REV: 1.4.1
The Kongsberg RDIOR420 is a remote digital input/output and relay module designed for use within marine control systems. Identified by part number 306713 at revision 1.4.1, this module handles the acquisition of digital input signals and the control of digital outputs and relay switching functions. It serves as a field-level interface component, enabling centralised control systems to monitor binary status signals and actuate relays across distributed onboard networks. In marine automation environments, reliable I/O and relay modules are critical to maintaining safe, responsive control of machinery, alarms, and auxiliary systems.
Key Features
✓ Provides remote digital input, digital output, and relay switching capability within a single compact module.
✓ Operates as part of a distributed control architecture — exact voltage ratings and response times are subject to confirmation based on system configuration.
✓ Compatible with Kongsberg marine control and automation platforms; specific panel or controller compatibility depends on the installed system version.
✓ Designed for installation in control cabinets or equipment rooms onboard; mounting arrangement and environmental rating are typical for marine-grade automation hardware.
✓ Direct replacement module for systems requiring like-for-like substitution; revision 1.4.1 should be verified against the installed system baseline prior to fitment.
Marine Applications
✓ Integrated bridge and automation systems requiring distributed I/O across multiple control nodes.
✓ Machinery monitoring and alarm management systems on commercial vessels and offshore units.
✓ Cargo and ballast control panels where digital status feedback and relay actuation are essential.
✓ Engine room automation and remote shutdown or interlock systems relying on hardwired digital signals.
✓ Vessel management systems on tankers, bulk carriers, offshore support vessels, and passenger ships.
