Accutech Base Radios

Accutech BR20 | BR21: Reliable, Scalable Wireless Communication for Industrial Monitoring

Overview:

Accutech BR20 | BR21 DIN Rail Mounted Base Radios

The Accutech BR20 and BR21 base radios form the backbone of any Accutech™ wireless instrument network, providing seamless communication with deployed field units in a local area star network. These DIN rail-mounted base radios make field data available to existing control systems via local serial or Ethernet Modbus™ interfaces. They support up to 100 field units each and can scale to 256 base radios, making them suitable for expansion.
