Accutech BR20 – Base Radio

 

At the heart of any Accutech wireless instrument network is the wireless base radio. The Accutech BR20 automatically communicates with deployed instrumentation field units attached to it in a local area star network and makes the field data available to an existing control system through a local serial Modbus interface. An optional integrated long-haul data radio, for links to centralised data collection sites, is available. One base radio can communicate with up to a maximum 100 field units. With the capability to scale up to as many as 256 base radios, Accutech easily accommodates your expansion plans.
