KNX Evaluation Unit for Temperature Sensors

The KNX T6-UN-B4 temperature evaluation unit has six inputs for T-100 orT-130 temperature sensors and four analogue/digital inputs, which can for example be used for buttons or T-NTC temperature sensors.

The temperature measurement values for all inputs can be processed with external measurement values to provide a combined value (total temperature, average temperature). The KNX T6-UN-B4 provides six switched outputs with adjustable threshold values. Six PI controllers control the heating and cooling (one- or two-stage). Logic gates can be used to set up additional operations.

Sensors for KNX T6-UN-B4:

N° 30516 T-NTC, for analogue/digital inputs
N° 30517 T-100, for temperature sensor inputs
N° 30518 T-130, for temperature sensor inputs

  • KNX T6-UN-B4 KNX T6-UN-B4
  • 6 temperature inputs for T-100 or T-130 sensors
  • 4 analogue/binary inputs, for example for buttons or T-NTC temperature sensors
  • Combined value calculation for all connected temperature sensors (proportion of internal measurement value and external value can be set as a percentage)
  • 6 switched outputs with variable thresholds (thresholds are set optionally by parameters or via communication objects)
  • 6 PI controllers for heating and cooling (one- or two-stage)
  • 4 AND and 4 OR logic gates with 4 for each input. 16 logic inputs in the form of communication objects can be used as inputs for the logic gates. The output of each gate can be configured optionally as 1-bit or 2 x 8-bit
  • Configuration via ETS
