The Kongsberg RDIOR420 (Part Number 306713) is a high-performance Remote Digital Input/Output and Relay module designed for industrial and marine automation systems. Engineered to work within the Kongsberg Marine Pro series, this module serves as a critical interface for signal acquisition and actuator control. It facilitates reliable communication between field devices—such as sensors, switches, and valves—and the central control system, ensuring precise monitoring and command execution in demanding environments.
Product Specifications
Model: RDIOR420 Part Number: 306713 Dimensions: 120 mm x 100 mm x 50 mm (standard DIN-rail mount form factor) Weight: Approximately 0.45 kg Origin: Norway Communication Interface: CAN Bus / Proprietary Kongsberg fieldbus Input Voltage: 24V DC nominal Degree of Protection: IP20 (intended for installation within protected cabinets/enclosures) Operating Temperature: -20°C to +70°C
Application Areas
The RDIOR420 is extensively used in marine vessel management systems, including engine room monitoring, alarm systems, and propulsion control. It acts as an I/O extension module, allowing the central controller to manage localized hardware without the need for extensive point-to-point wiring back to the main cabinet. It is also suitable for industrial automation environments where remote signal handling and relay switching are required for safety-critical operations.
Product Usage Guide
To integrate the RDIOR420, mount the unit onto a standard 35mm DIN rail within a controlled cabinet environment. Connect the power supply (24V DC) to the designated terminals, ensuring the correct polarity. Connect the digital inputs to your field sensors and the relay outputs to your control devices (e.g., solenoids or alarm beacons). Once physically connected, the module must be addressed via the system configuration software to allow the master controller to recognize its unique node ID. Ensure that the communication bus is correctly terminated at both ends to prevent signal reflection. Always verify the relay contact ratings before connecting high-load devices.
Frequently Asked Questions (Q&A)
What is the primary function of the RDIOR420? Its primary role is to act as a remote expansion node, allowing for distributed digital I/O and relay switching to reduce cabling complexity. Is this module hot-swappable? No, it is recommended to disconnect the power supply before removing or installing the module to prevent electrical damage. How do I configure the relay outputs? The relay states are managed by the main automation controller; however, logic mapping must be configured in the system’s primary engineering software. What does the status LED indicate? The LEDs provide a visual diagnostic of the module’s power status and communication bus activity. If the communication LED is flashing red, check for wiring faults or bus address conflicts. Can this module operate in high-vibration areas? Yes, the RDIOR420 is marine-certified and designed for high-vibration environments, provided it is securely mounted in a vibration-dampened cabinet.
