Line termination device with terminating resistor MODKON® LA- Modbus
MODKON® LA-Modbus T3 line termination device with terminating resistor, in an impact resistant plastic housing with quick-locking screws.

The Modbus device serves as an active bus termination for RS485 networks (ANSI TIA/ EIA-485), such as Modbus RTU. It includes a terminating resistor with a biasing network, which pre-defines the bus signals to a safe value (fail-safe biasing) during bus idle time.

The bus termination can be fully switched on or off via DIP switches. This allows various operating scenarios to be tested in a simple manner whenever servicing is needed.
For very long network cables, both end points can also be provided with an active bus termination to improve interference immunity under harsh environmental conditions.
