KNX Modbus Gateway 886

The KNX Modbus Gateway 886 is a compact Modbus interface with 250 freely configurable channels. The device enables easy integration of Modbus devices that support the RTU protocol via RS-485 and can act as a Modbus master or slave.

 

The assignment between KNX objects and Modbus registers can be configured via parameters in the ETS - no further tool is needed. Two buttons and three LEDs allow local operation and visualization of the device status.
