2. Specifications

The main function of BA11 is auto switching of 120 Ω line termination at RS-485 bus

to keep the communication balanced when Modbus slave device is disconnected. The

BA11 box detects if a Modbus slave device is connected to the port (J1..J4). If not, the

communication terminator is connected. If a Modbus slave is connected to a port (J1..J4),

the terminator is disconnected automatically.

2-1. Environment and operational conditions

- Power supply voltage +2.7 VDC to +5.5 VDC

- Max. power consumption* < 30 mW (@ +5.5 VDC, without connection of field devices)
