Information
TA 4 S KNX – 4-channel binary input/output, flush mounting
Item no.: 4969224
Product Description
The TA 4 S KNX is a versatile 4-channel pushbutton interface for KNX systems, usable as both binary input and output. The device offers a 6-wire cable connection and allows for free assignment of functions such as switching, dimming, blind control, value transmitter, sequences, temperature measurement and LED control. Thanks to the two integrated NTC inputs, precise temperature measurement is possible from -5 °C to +100 °C, ideal for room or floor temperature monitoring.
The TA 4 S KNX can be easily installed in standard flush-mounted boxes and directly combined with conventional pushbuttons or switches. The flexible LED control with an output current up to 3 mA enables easy control of both standard and low current LEDs. Each input can be individually parameterized as an output with adjustable blinking or pulse function. The color coding of wire pairs ensures a clear and fast installation.
Programming and parameterization are carried out via ETS (Engineering Tool Software), allowing application programs and parameters to be easily configured. Various accessories are available, including different temperature sensors for a wide range of applications.
Applications
- Control of lighting, dimmers, blinds and other devices via KNX
- Temperature measurement with NTC sensors, e.g. for room or floor temperature
- Expansion of KNX installations with additional binary inputs and outputs
- Detection of switching pulses or states
- Control and indication via LEDs (status and signaling functions)
Features
- 4-channel pushbutton interface, usable as binary input or output
- Freely programmable functions: switch, pushbutton, dimming, blinds, value transmitter, sequences, temperature measurement, LED control
