UP 220/21 KNX Pushbutton Interface 2xPotential-Free Contacts LED Output Flush Mount 5WG1220-2AB21

The KNX pushbutton interface is a compact flush-mounted device designed for installation in switch and socket boxes with a diameter of 60 mm. It provides two inputs/outputs configurable for potential-free contacts or for controlling an LED indicator, making it ideal for integrating conventional pushbuttons into a KNX system.

Key Features

The unit generates its own sensing voltage for potential-free contacts, eliminating the need for an external supply
Inputs support a maximum cable length of 10 m using unshielded twisted cable
Input functions include locking via blocking objects, adjustable duration of long button press, and configurable contact type as normally open or normally closed
Transmission parameters support adjustable cyclic transmission and configurable transmission after bus voltage recovery
The device evaluates short and long button presses and supports switching on/off/toggle, 8-bit and 16-bit value transmission, single-button dimming, two-pushbutton dimming with stop telegram, and one or two-pushbutton shutter/blind control
Scene store and recall are available as 8-bit values in conjunction with a scene module
Pulse counting with limit value monitoring is supported in 8-bit, 16-bit, and 32-bit modes
