KONGSBERG RMP201-8 Remote Multi-functional I/O Module for Ships

KONGSBERG RMP201-8 Ship Remote Multi-Purpose I/O Module
I. Basic Product Positioning
Brand Series: Norwegian Kongsberg Maritime (Kongsberg Maritime), belonging to RIO200 / K-Chief 600 / K-Master ship distributed automation system
Product Type: Remote Multi-Purpose I/O (Remote Multi-Function Input Output Unit), Distributed Field Data Acquisition Node, Model Suffix -8 indicates standard 8-core channels
Core Function: On-site collection of sensor / switch signals in engine room / pump room / steering gear room, issue control instructions for valves / pump groups, communicate through ship bus and control room mainframe, significantly reducing long-distance ship cable laying
Application Scenarios: Merchant ships, offshore platforms, special ship marine engine monitoring, ballast, fire protection, fuel and lubricating oil system interlocks

Hardware Channels and Electrical Parameters
1. I/O Channel Configuration
8 configurable multi-function channels: Support digital contact input, digital transistor output, 4–20mA analog, frequency / pulse, PWM signal free software configuration
Optical isolation 2500VDC, resistant to strong electromagnetic interference from large ship motors and inverters
Digital Input: Passive contact type, suitable for pressure / temperature / level switches, emergency stop buttons
Digital Output: Maximum 500mA@24VDC per channel, drives relays, solenoid valves
Analog Range: 0–5V / 0–10V / 4–20mA, 16-bit high-precision acquisition

IV. Core Function Advantages
Software Free Configuration
Channels do not require hardware jumpers, upper-level software can switch input / output / analog / pulse mode with one-click, the same module can be adapted to multiple on-site measurement points, spare parts have strong universality
Complete Hardware Self-Diagnosis
Channel break, short circuit, overcurrent, bus interruption, power supply undervoltage real-time alarm, fault codes uploaded to control room HMI, quickly locate the fault point in the engine room
Ship High Reliability Design
Full board three-proof coating, wide voltage tolerance, surge filtering; Supports multi-module bus hand-in-hand cascading, single node failure does not cause the entire bus to fail
Distributed Architecture Reducing Burden
Install nearest equipment, replace pulling dozens of cables from the control room to the engine room, reduce wiring costs, reduce ship body penetration holes, improve system stability
V. Typical Ship Application Points
Oil / Cooling Water Pressure and Temperature Switch Collection, Pump Operating Status Feedback Ballast tank liquid level, valve opening feedback and remote valve switching control
Interlock for fire pump and emergency fan start/stop, fire alarm probe signal collection
Local monitoring circuits for generator auxiliary equipment, air compressor, boiler
Monitoring of process medium pressure and flow for FPSO and offshore platforms
