Description
The Kongsberg RDIOR420 (Part Number 306713) is a sophisticated Remote Digital Input/Output and Relay Module engineered for industrial automation, specifically within Kongsberg’s K-Chief, K-Bridge, and DataChief systems. Unlike standard I/O modules, the RDIOR420 integrates both digital signal processing and high-current relay outputs, allowing it to interface directly with field-level equipment such as solenoid valves, alarm sirens, motor starters, and status limit switches. By moving the relay switching logic closer to the physical equipment, this module minimizes cabling complexity and enhances system responsiveness, ensuring reliable performance in harsh maritime environments.

Important Implementation Note: The RDIOR420 is designed to handle inductive loads through its relay contacts, but external flyback diodes or RC snubbers should be used if switching high-voltage or highly inductive solenoid coils to protect the relay contacts from arcing. Additionally, ensure that the module’s “Node Address” is set correctly via the onboard dip-switches or software configuration tool to match the system loop address specified in your vessel’s I/O wiring diagrams.
