Signal converter AST420 Series Alia Vietnam

Introducing the AST420 Series Alia Vietnam signal converter

AST420 series signal converter  is a device that supports conversion between analog signals and radio signals.

It aims to convert 4-20 mA analog signals into radio signals for remote transmission of analog signals without cables, widely used in the case of transmitting analog signals over long distances.

Wireless communication distance up to 600 meters, saving a lot of cables.

It also isolates the power source of the device's signal receiver and control end to enhance security.
