The KNX-GW-MODBUS-SK07-RS485 is a compact in-wall Modbus RTU master that polls up to 31 Modbus devices over RS485. Its 32 freely assignable datapoints are scaled and mapped to KNX in ETS.

The gateway fits an SK07 in-wall housing, offers a 12 VDC output for Modbus devices and requires a 24-32 VDC auxiliary supply. Baud rate, parity and reading cycle are all set in ETS.

Key Features

  • Modbus RTU master with 32 freely assignable, scalable datapoints
  • 300-115,200 baud, parity even/odd/none, device IDs 1-247
  • Multiplier/offset scaling; KNX 1, 8, 16 and 32-bit datapoint types
  • Reading cycle adjustable from 10 s to 12 h
  • RS485 for up to 31 Modbus slaves; 12 VDC/100 mA output
  • Auxiliary supply 24-32 VDC, max. 100 mA (required)
  • SK07 in-wall housing, 50 x 50 x 20 mm (1.97 x 1.97 x 0.79 in), IP20; ETS app KNX-GW-ModBus
