The KNX-GW-MODBUS-SK10-RS485 is a surface-mount Modbus RTU master in an IP54/65 housing, suited to plant rooms and mechanical spaces. It polls up to 31 Modbus slaves over RS485 and maps 32 scalable datapoints to KNX.
Configuration is done in ETS, including scaling and reading cycle. The gateway provides a 12 VDC output for Modbus devices and requires a 24-32 VDC auxiliary supply.
