Description
Product Introduction
The Kongsberg RAo-8xe Remote Analog Output Module, part number 333505, is a distributed I/O module designed for marine automation systems, including compatible K-Chief installations. Revision C identifies the version specified in this product listing.
The module provides eight analog output channels for converting control-system commands into voltage or current signals. These outputs can be configured for compatible analog signal ranges and scaled to engineering units, allowing the module to interface with instruments and other equipment in a marine automation system.
The RAo-8xe supports remote configuration, self-checking, time stamping, and CAN bus communication. Its design allows installation near the equipment being controlled, helping reduce long analog signal cable runs.
This module is suitable for maintenance and replacement applications when the part number, revision, system configuration, and required output settings match the original installation.
