Modbus RS485 to Modbus TCP

Modbus RS485 to Modbus TCP Infographics

The QE-BR-ETH485 is a Modbus RTU to Modbus TCP bridge. Using the T-Bus connection of the QEED DIN Rail mount Modbus input-output modules, you can tie many together and then convert the Modbus RTU unit to Modbus TCP. The QE-BR-ETH485 can be used with up to 10 client connections and be galvanically isolated from the Modbus TCP to the Modbus RTU RS485.
Local indication is provided to see that the network is healthy and active. The Modbus RTU can be connected using the terminals or the T-Bus connection, and the Modbus TCP uses an RJ45 connection. The RS485 can operate up to 11520 kbps, and the Modbus TCP is 10/100Base-T.
