1.
Description
The
Interface KNX B8-TH
has eight binary inputs and two additional sensor inputs
for temperature or temperature and air humidity. They are used to integrate signals
and values from conventional buttons and sensors into the KNX building bus.
The application software of the
Interface KNX B8-TH
contains both switch outputs
for temperature and humidity as well as PI controllers for heating/cooling and ventila-
tion. The binary inputs can be configured as switches, up/down buttons, dimmers or
encoders in various configurations.
Due to its compact design, the interface fits into a switch box. The binary contacts are
connected using the cables supplied with the delivery.
Functions:
•
8 binary inputs
(button interfaces for potential-free contacts)
•
1 input for temperature sensor
T-UP basic or
temperature/air humidity
sensor
TH-UP basic. Sensors for wall mounting in 55 mm standard frames of
switch programmes
•
1 input for temperature sensor
T-NTC-ST
•
Bus warning with regard to whether the values for temperature and air
humidity are within the comfort field (DIN 1946).
•
Dewpoint calculation
•
Switch outputs for temperature and air humidity depending on threshold
values, adjustable via parameters or communication objects.
•
PI-controller for heating
(one or two-stage) and
cooling
(one or two-stage)
according to temperature. Regulation according to separate setpoints or basic
setpoint temperature
•
PI controller for humidity
according to humidity: Dehumidifying/
humidifying (single level) or dehumidifying (single or double level)
•
4 AND and 4 OR logic gates
, each with 4 inputs. All switching events as well
as 16 logic inputs (in the form of communications 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 is made using the KNX software ETS. The
product file
