RDM9HD-04RDM-9 Product Overview

A great deal of applications need reliable data connections based on a  wireless solution. Targeting these problems, UNAOHM has developed a high speed radiomodem family designed to meet  the growing wireless connection needs in many applications.

RDM 9 type radiomodem opens new possibility of application for data transmission via radio, having excellent characteristics of data speed (up to 9600 bit/s) associated to really low activation time.

Others relevant characteristics are the low power consumption and the reduced dimension obtained, thanking to the extensive application of SMT technology and multistrate printed board; everything enclosed in an IP54 sealed box that enables it to be utilized in the most severe environmental conditions
