Product Specification: KONGSBERG RDIOR420 Remote Digital I/O and Relay Module
KONGSBERG RDIOR420 is a modular remote I/O module designed for industrial automation, marine control, and process monitoring systems. It combines digital input/output (DI/DO) and relay channels to interface with sensors, actuators, and control systems in harsh environments.
1. Product Description
The RDIOR420 is a hybrid I/O module with the following key features:
16 Solid-State DI/DO Channels: Configurable as digital inputs or outputs for sensor/actuator integration.
16 Relay Channels: Normally closed (NC) or normally open (NO) for switching high-power loads.
Redundant Communication: Dual Remote I/O Process Bus (RBUS A/B) interfaces for fault-tolerant communication with host systems (e.g., RCU510).
Short-Circuit Protection: On solid-state output channels to prevent damage.
Loop Monitoring: For detecting faults in the I/O loop.
Galvanic Isolation: Between communication ports and module circuitry to protect against electrical noise.
Input: 0–24V DC Output: 5A max per channel (relays)
Response Time
<10 ms (solid-state), relay-dependent
Environmental
Operating: -25°C to +60°C Storage: -40°C to +85°C
Certifications
Compliance with maritime standards (e.g., DNV GL)
3. Application Areas
Marine Automation: Vessel control systems (e.g., K-Chief 700), engine monitoring, and pump/fan control.
Industrial Control: Factory automation, power plants, and process industries.
Remote Monitoring: Offshore platforms, oil/gas facilities, and distributed infrastructure.
4. Key Features & Advantages
Modular Design: Easy to install and replace via DIN rail mounting.
Flexibility: Configurable I/O channels for diverse sensor/actuator types.
Reliability: Redundant communication and built-in diagnostics for continuous operation.
Safety: Fault-safe outputs, loop monitoring, and compliance with SIL 1 standards.
5. Supplier & Pricing
New Units: Prices vary by configuration (e.g., with/without redundant bus).
Refurbished Units: Available from marine automation suppliers .
Authorized Dealers: KONGSBERG Maritime, Shanxi Xinyeda, and global industrial automation distributors.
6. Notes & Precautions
Model Variability: Some sources report 40 DI/DO channels , suggesting variant configurations. Verify specifications with suppliers.
Compatibility: Works with KONGSBERG’s RCU (Remote Control Unit) and RMP (Remote Module) series.
Installation: Requires proper grounding and cable management to ensure signal integrity.
