KONGSBERG RMP200-8 – Eight‑channel remote multiplexer module for reliable signal distribution in marine and industrial control

The KONGSBERG RMP200-8 is part of a rugged remote I/O and signal multiplexing family that’s widely used on vessels and in harsh industrial sites to collect multiple field signals and push them into a control or monitoring network. From my experience, the “-8” variant is selected when you need eight isolated channels in a compact footprint, typically for serial/NMEA sensor fan‑in, alarm expansion, or segmenting RS‑422/RS‑485 links with clean isolation. You might notice that it slots neatly into existing KONGSBERG automation architectures, but it also plays nicely with third‑party PLC/DCS systems via standard interfaces.

Key Features

• Eight isolated channels – Typically used for RS‑422/RS‑485 or NMEA‑0183 signals, helping consolidate multiple sensors into one clean data backbone.
• Marine‑grade robustness – Built for vibration and electrical noise found on ships and offshore equipment; stable performance in engine rooms and control cabinets.
• Flexible I/O mapping – Channel assignments can be configured for pass‑through, multiplexing, or distribution depending on the sub‑variant and project standards.
• 24 VDC power – Runs on the common shipboard/plant 24 VDC bus; reverse‑polarity and transient protection are typically included for safety.
• Status indicators – Front‑panel LEDs for power and channel activity make first‑line troubleshooting much faster during commissioning.
• Compact, serviceable design – Field wiring on pluggable terminals; makes on‑board swap or inspection straightforward for technicians.
• Interoperability – Works with mainstream marine automation and third‑party PLC/DCS systems via standard serial and, in many cases, Ethernet diagnostics.

Technical Specifications

“We used the RMP200-8 to clean up a cluster of RS‑422 gyro and wind sensors feeding the bridge system. The isolation solved our noise, and commissioning took less than an afternoon,” a superintendent from a North Sea PSV told us—not perfect phrasing, but that’s their candid feedback.

Application Fields

• Vessel automation and navigation networks – Multiplex NMEA/serial sensors (gyro, wind, speed log) into ECDIS, DP, or IAS systems.
• Engine room and machinery spaces – Distribute serial data to monitoring panels while maintaining galvanic isolation.
• Offshore platforms and onshore terminals – Reliable field signal fan‑in for SCADA/PLC rooms with long cable runs.
• Industrial plants – RS‑485 segment protection and repeat for drives, analyzers, and legacy instruments.

Advantages & Value

• Reliability under noise – Isolation and robust transceivers help retain signal integrity on long, mixed‑ground cable runs.
• Compatibility – Works with KONGSBERG ecosystems and most third‑party PLC/DCS platforms that accept RS‑422/485 or NMEA data.
• Cost control – Centralizes multiple sensors into fewer control ports, reducing extra interface cards and wiring time.
• Lifecycle support – Spares availability and straightforward field replacement lower downtime during port calls or planned outages.

Installation & Maintenance

• Cabinet & environment – Install in a ventilated, dry control cabinet (IP54 or better). Maintain ambient −15 to +55 °C; avoid condensation and salt mist.
• Power & grounding – Feed from a clean 24 VDC supply with proper grounding. Use shielded twisted‑pair for serial lines; terminate RS‑485 as per segment length.
• Wiring practices – Keep high‑power cables separate from signal runs. Label channels 1–8 clearly to simplify future service.
• Routine checks – Inspect terminal tightness and LED status quarterly. Clean dust with dry air; avoid solvents on the enclosure.
• Firmware & backups – Where firmware applies, keep a known‑good image on file and update during planned maintenance windows.

Quality & Certifications

• CE compliant; RoHS alignment for hazardous substances (typical for this class of equipment)
• Marine class type approvals (e.g., DNV, ABS) are commonly available for KONGSBERG modules; confirm exact approval sheet for the RMP200‑8 sub‑variant
• Manufacturer warranty: 12 months

One thing I appreciate is how forgiving the RMP200‑8 is during retrofits—wire it clean, set the channel modes, and it just behaves. If you can share your exact interface list (sensor types, baud rates, cabinet space), we’ll match the sub‑variant and ship to your schedule.
