SENCOM™ Active Junction Box, BA11

The BA11 Active Junction Box is designed for a wide range of industrial environments and is tested against the latest standards.

The model BA11 Active Junction Box has the ability to connect multiple Yokogawa SA11 smart adapters, acting as slave devices, to a host system using one trunk connection, resulting in a cost-effective solution.

The BA11 Active Junction Box automatically senses a (dis)connected smart adapter, and as a result, switches the 120 Ω line termination for keeping the RS-485 communication balanced. This way, a plug and play solution is provided without the need for manually placed terminating resistors.

Features

  • Auto-balancing of RS-485 digital bus
  • Star topology for connecting multiple (maximum 4) Yokogawa smart adapters.
  • Indoor and outdoor application
  • Application in industrial environments
  • Wall and pipe mounting options
