The KNX-GW-MBUS-SK08 provides three independent M-Bus master ports, each reading one meter. Because every port has a single meter, the meters can be read without assigning unique M-Bus primary addresses, which simplifies retrofits and mixed meter installations.

Up to 32 freely divisible values are passed to KNX. The gateway is bus powered, configured in ETS and housed in a gray IP54/65 wall-mount enclosure.

Key Features

  • 3 separate M-Bus master ports, one meter each (EN 13757-2/3)
  • Meter detection independent of M-Bus primary address
  • Up to 32 freely divisible data values mapped to KNX
  • Reading cycle adjustable from 10 s to 12 h
  • Bus powered (approx. 550 mW), no auxiliary supply
  • IP54/65 gray ABS wall housing, 115 x 65 x 55 mm (4.53 x 2.56 x 2.17 in)
  • Operating range -20 to +55 °C (-4 to 131 °F)
