JUNG KNX Push-button Interface 2-gang Secure 400021SE

The JUNG KNX Push-button Interface 2-gang Secure (model 400021SE) is a flush-mounted device for connecting two potential-free contacts to the KNX bus. It supports KNX Data Secure for enhanced communication protection and is configurable via ETS 5.7.3 or higher. The interface enables switching, dimming, blind control, value transmission, scene recall, sequence control, and counter functions per input. Integrated logic functions (AND, OR, XOR, NOT) allow complex automation scenarios without additional devices.

Advantages

Secure KNX communication with Data Secure; flexible input configuration; compact flush-mount design; low power consumption; wide operating temperature range.
