The Kongsberg RDIOR400 is a high-performance, ruggedized remote I/O module designed specifically for the K-Chief automation and Maritime Discrete Architecture (MDA) systems. This unit functions as a versatile interface between field instrumentation and the centralized control network, providing a mix of digital inputs and relay outputs. The RDIOR400 is engineered to withstand the harsh environments of engine rooms and open deck installations, ensuring reliable data acquisition and command execution for mission-critical marine applications.

 

Product Parameters

The RDIOR400 is built for seamless integration within the Kongsberg RIO (Remote Input/Output) network.

 

Technical Description

The Kongsberg RDIOR400 utilizes a high-speed internal processor to manage 12 digital input channels and 8 relay output channels simultaneously. Each digital input is optically isolated to protect the internal electronics from common-mode voltages and electrical noise typical in shipboard environments. The relay outputs provide potential-free switching, making them ideal for driving solenoid valves, motor starters, or alarm indicators. The module features dual power supply terminals for redundant 24V DC lines, ensuring continuous operation even if one power source fails. Integrated LED indicators provide local status for each I/O channel and the health of the communication bus.

 

Country of Origin

This marine automation module is designed and manufactured in Norway by Kongsberg Maritime AS, adhering to the strictest international maritime regulations and environmental standards.

 

Application Fields

The RDIOR400 is a standard component in Kongsberg K-Chief 600 and K-Safe systems:

• Engine Monitoring: Digital status tracking for pumps, fans, and auxiliary engines.
• Cargo Handling: Relay control for valve actuators and hydraulic power units.
• Alarm & Monitoring (AMS): Collecting binary signals from pressure switches, level switches, and fire detectors.
• Ballast Management: Controlling the sequence of ballast pumps and tank vents.
• Power Management Systems (PMS): Interfacing with circuit breaker auxiliary contacts and trip coils.

Product Usage Instructions

1. Mounting: Install the RDIOR400 on a standard 35mm DIN rail inside a ventilated marine-grade enclosure. Ensure the module is grounded via the DIN rail or the dedicated PE terminal.
2. Redundant Power: Connect two independent 24V DC power sources to the V1 and V2 terminals to take advantage of the module’s internal power redundancy logic.
3. CANbus Wiring: Use approved shielded twisted-pair cable for the CANbus communication link. Ensure the termination resistors are enabled at the physical ends of the bus segment.
4. Field Wiring: Connect digital inputs (switches/sensors) to the input terminals. For relay outputs, ensure the load does not exceed the 2A contact rating to prevent premature relay failure.
5. Addressing: Set the unique module address using the onboard DIP switches before powering up the system. This allows the master controller (DPU) to identify the RDIOR400 on the network.
