The SK08-T8-PT100 is an eight-channel KNX measuring and control unit for up to eight external PT100 temperature probes. Its IP54/65 surface-mount housing is suited to indoor, outdoor and damp-room installation.

Use it to monitor, control and log heating and cooling circuits from a single bus device. Resolution is 0.01 °C (0.02 °F) with ±0.3 °C (±0.54 °F) accuracy, and the measuring range runs from -50 to +400 °C (-58 to 752 °F) depending on the probe used. The unit is bus powered and configured in ETS with the Arc_S8 application. Probes are ordered separately.

Key Features

  • 8 temperature inputs for PT100 probes (not included)
  • Range -50 to +400 °C (-58 to 752 °F) depending on probe; 0.01 °C (0.02 °F) resolution, ±0.3 °C (±0.54 °F) accuracy
  • Monitoring, control and logging of heating and cooling circuits
  • IP54/65 surface-mount housing for indoor, outdoor and damp locations
  • Bus powered, 10 mA bus load; no auxiliary supply
  • ETS application Arc_S8 (S8-T8)
