The KONGSBERG RMP420 is a versatile and rugged Remote I/O module designed specifically for the maritime and offshore industries. As a core component of the Kongsberg Maritime K-Chief and AutoChief control systems, it provides a reliable interface between field sensors, actuators, and the central processing units.

 

Product Overview

The RMP420 (Remote Monitoring and Processing) unit is engineered to handle distributed signals in harsh environments. It excels at converting analog and digital field signals into networked data, allowing for reduced cabling and simplified installation across large vessels or offshore platforms. Its modular nature ensures that it can be adapted for various monitoring and control tasks, from engine room automation to bridge systems.

Technical Datasheet & Parameters

 

Country of Origin

The KONGSBERG RMP420 is designed and manufactured in Norway.

 

Application Fields

• Machinery Monitoring: Tracking exhaust temperatures, oil pressures, and cooling water flow.
• Alarm and Monitoring Systems (AMS): Processing safety-critical alarms across the vessel.
• Pump and Valve Control: Distributed management of ballast, fuel, and cargo systems.
• Power Management: Interfacing with switchboards and generator control units.
• HVAC Control: Managing climate control systems in accommodation and engine spaces.

 

Technical Description

The RMP420 utilizes advanced signal conditioning to ensure high accuracy even in electrically noisy environments typical of shipboard installations. It features a built-in microprocessor for local signal processing and self-diagnostics. The module supports redundant communication links, ensuring that a single cable fault does not result in the loss of critical data. Its galvanically isolated inputs protect the central control network from external electrical surges or ground faults.

 

Usage Instructions

1. Mounting: Install the module on a standard 35mm DIN rail within a protected enclosure or control cabinet.
2. Termination: Connect field wires to the spring-loaded or screw terminals. Ensure that shielding is properly grounded to the cabinet’s earth bar.
3. Network Integration: Connect the module to the K-Chief/AutoChief process bus using the designated CAN bus ports.
4. Addressing: Set the unique module address using the onboard DIP switches or via software configuration as per the system project plan.
5. Status Check: Monitor the LED indicators on the front panel; a steady green ‘Power’ LED and flashing ‘Status’ LED indicate normal operation.
