Product Overview
The Kongsberg RMP201-8 is a marine-grade remote multipurpose input/output module designed for Kongsberg K-Chief and AutoChief distributed vessel automation systems. As a distributed field signal interface node, it collects field sensor signals and executes local control outputs, bridging physical equipment and central controllers. This flexible universal I/O unit greatly simplifies cabling layout on vessels and offshore platforms by enabling decentralized signal acquisition close to machinery compartments.
Core Hardware & Functional Characteristics
Equipped with 8 independently software-configurable channels, the RMP201-8 supports multiple signal modes without hardware jumper modification: digital input, digital output, analog input (4–20mA, 0–10V), analog output and potentiometer signals.
- 16-bit high-precision A/D conversion guarantees accurate measurement for pressure, temperature, liquid level and other process variables
- Dual redundant RBUS communication interfaces ensure reliable data exchange with main controllers, avoiding single-point communication failure
- Comprehensive onboard self-diagnostic function; monitors channel short-circuit, open circuit, power supply abnormality and bus communication faults, and uploads fault alarms to system HMI
- Front panel LED indicators provide intuitive visual status for power, bus activity and individual channel operation
- DIN rail mounting design with compact dimensions; conformal coated PCB enhances resistance against humidity, vibration and salt mist in marine environments
- Certified by DNV GL, ABS, LR and other major marine classification societies, fully compliant with IACS marine equipment standards
- Operating power supply: 24 VDC, wide tolerance range for unstable onboard power networks
Typical Application Scenarios
The RMP201-8 is widely deployed on merchant ships, offshore support vessels, drilling rigs and floating production units. It serves as essential front-end hardware for Kongsberg marine automation solutions:
- Engine room monitoring: pump status feedback, temperature and pressure signal collection
- Ballast and cargo control system signal acquisition
- Fire & gas safety monitoring and auxiliary valve control
- Power management system auxiliary signal processing
- Retrofit and maintenance of legacy K-Chief automation racks
Sourcing & Commissioning Guidelines
- Confirm full part number RMP201-8 during procurement; different hardware revisions are not fully interchangeable without compatibility verification.
- ESD anti-static protection is required when handling the module to prevent circuit damage.
- After installation, complete channel configuration via engineering software, define signal type for each channel and verify RBUS bus wiring and terminal resistance.
- Conduct full signal simulation test to confirm data acquisition and control output before restoring vessel operation.
Common Field Faults
- Intermittent signal reading failure: loose terminal wiring or degraded field sensor cables
- Communication offline: incorrect bus termination, damaged RBUS cable or address conflict
- Continuous channel fault alarm: sensor short circuit or internal channel circuit aging
