Description

Product Overview

The KONGSBERG RMP201-8 is an eight-channel Remote Multi-Purpose I/O module in the Kongsberg RIO200 family. It is designed for distributed marine automation applications, including K-Pos dynamic positioning systems and other control architectures requiring flexible remote signal acquisition and output. The module combines six common-ground multipurpose channels with two individually isolated channels. Depending on configuration, the channels can handle digital input, digital output, analog input, analog output, and potentiometer signals.

Communication and module power are provided through dual RBUS interfaces, supporting redundant communication with remote controller units. The module accepts single or dual 24 VDC supplies and incorporates protection, diagnostics, configurable fail-safe behavior, and hot-swap capability. Kongsberg documentation identifies Part No. 324400 for this module.

Key Features and Benefits — RMP201-8

• Eight configurable remote I/O channels for mixed automation signals.
• Six multipurpose channels support DI, DO, AI, AO, and potentiometer functions.
• Channels 6 and 8 provide additional galvanic isolation.
• Dual RBUS connections support redundant communication and power arrangements.
• 2 Mbps RS-485-based RBUS communication reduces the need for separate communication wiring.
• Built-in diagnostics monitor internal voltages and module operation.
• Configurable fail-safe functions can freeze outputs or apply predefined values following communication loss.
• Hot-swap replacement capability is useful during maintenance of distributed control cabinets.

Installation and Maintenance — RMP201-8

Installation should follow the applicable Kongsberg engineering documentation. Verify the RBUS A/B connections, 24 VDC supply arrangement, module address, grounding scheme, and field-channel configuration before commissioning. The module uses address switches with selectable addresses from 1 to 99, while the front status LED provides operating and fault indication.

During replacement, record the existing part number, revision, serial number, address setting, and connected I/O configuration. ESD precautions are important when handling the electronics. Personally, I would also verify whether channels 6 and 8 are being used for isolated signals before substitution, since that isolation is a meaningful part of the module’s architecture.

Product Warranty — RMP201-8

Warranty terms depend on the supplier and the condition of the spare, such as new original, surplus, refurbished, or tested stock. Procurement records should specify the exact Kongsberg part number, hardware revision, serial traceability, test status, and applicable return conditions.

The KONGSBERG RMP201-8 is a flexible eight-channel RIO200 remote I/O module with redundant RBUS communication, mixed-signal capability, diagnostics, and hot-swap functionality. Kongsberg certification documentation also lists it as an approved I/O module for K-Pos platform configurations.
