Information
TA 4.1 KNX – 4-channel binary input/output, flush mounting
Data Secure
Item no.: 4969274
Product Description
The TA 4.1 KNX is an advanced four-channel pushbutton interface for KNX systems, suitable for use as both binary input and output. Thanks to KNX Data Secure, data is exchanged securely via the KNX bus. The six-wire cable connection enables flexible and fast installation. Free assignment of functions such as switching, dimming, blind control, value sender, sequences, temperature measurement, and LED control offers maximum versatility in KNX installations.
The four inputs can be individually configured as binary input or output and can be linked to conventional pushbuttons/switches, easily installed in standard flush-mount boxes. Two inputs are switchable for connecting Theben temperature sensors for accurate temperature measurement between -5 °C and +100 °C, e.g., for room or floor temperature control.
The TA 4.1 KNX enables flexible LED control with an output current up to 3 mA, allowing both standard and low-current LEDs to be controlled directly (no series resistor required). Color coding of the wire pairs makes installation clear and safe.
Parameterization and programming are performed via ETS software. Application programs, parameters, and group addresses can be easily set. Accessories such as temperature sensors for various applications are optionally available.
