Product Overview

The Kongsberg RCU502I 421768 is a ruggedized Remote Control Unit (RCU) designed

for mission-critical industrial automation and maritime control systems.

Part of Kongsberg’s K-Chief series, this module serves as a decentralized processing

node for real-time monitoring and control in harsh environments.

The Kongsberg RCU502I integrates seamlessly into distributed architectures,

offering deterministic I/O handling, advanced diagnostics, and fail-safe operation.

Its primary role is bridging sensors/actuators with central systems (e.g., Kongsberg’s K-Log or K-Chief 600),

ensuring high availability in offshore platforms, marine vessels, and energy installations.

Engineered to withstand extreme temperatures, vibration, and corrosive atmospheres,

the RCU502I 421768 is the backbone for safety-critical automation where downtime is unacceptable.

Key Features and Operational Benefits

High Availability & Fault Tolerance: Dual-processor redundancy with “hot standby” failover

ensures uninterrupted operation during CPU faults.

Built-in diagnostics continuously monitor hardware health, network integrity,

and I/O signal quality, triggering automated alerts via Kongsberg’s K-Chief software suite.

Extreme Environment Resilience: Sealed aluminum housing withstands salt spray,

high humidity, and mechanical shocks. Compliant with IEC 60945 marine standards,

the RCU502I 421768 operates reliably in engine rooms, offshore rigs, or Arctic environments without derating.

Scalable I/O Architecture: Modular design integrates digital/analog I/O cards

(e.g., RAI-322 analog input, RDO-411 relay output) via backplane expansion.

Supports thermocouples, RTDs, 4–20 mA signals, and high-voltage discrete I/O.

All configurations are managed through Kongsberg’s Windows-based configuration tool.

Cybersecurity Hardened: Features hardware-enforced security with authenticated firmware updates,

role-based access control, and encrypted communications to prevent unauthorized access.
