Kongsberg RDIOR420 Remote Digital Input/Output and Relay Module
I. Product Overview
The Kongsberg RDIOR420 is a remote digital input/output and relay module (Remote Digital Input/Output and Relay Module) manufactured by Kongsberg Maritime, Norway, used for distributed I/O acquisition and output control in Kongsberg marine automation systems (such as K-Chief 500/600, DataChief 2000, etc.). The module contains 16 individually configurable solid-state digital input/output channels and 16 relay channels (NC/NO), totaling 32 I/O channels.
The RDIOR420 communicates with host control computers (such as the RCU remote control unit) via dual redundant remote I/O process bus interfaces (RBUS A and RBUS B, galvanically isolated RS485), providing redundant and reliable signal transmission. The module is powered by 24VDC with typical power consumption of 8W, featuring short-circuit protection and loop monitoring on solid-state output channels, suitable for ship engine room, bridge and other automation control environments.
The RDIOR420 belongs to the same Kongsberg remote I/O platform as the RMP420 (remote multipurpose I/O module) and RTB420 (remote termination board). It has passed type approval by Lloyd's Register and other classification societies, and is widely applied in the automation and monitoring systems of merchant vessels, offshore vessels and marine engineering platforms for digital signal acquisition, processing and relay output control.
