Hager TYBS704A KNX Binary Input 4-Channel Flush-Mounted

Integrating conventional switches, push-buttons, or potential-free contacts into a KNX installation can be challenging without a dedicated interface. The Hager TYBS704A binary input solves this by converting up to four independent binary signals into KNX telegrams, enabling seamless control of lighting, blinds, and other building automation functions.

Who is it for

This device is intended for KNX system integrators and electricians who need to connect traditional switches or sensors to a KNX bus. It is suitable for residential and commercial projects where flush-mounted installation is required.

Main features

• 4 potential-free inputs for connecting switches, push-buttons, or contacts
• Flush-mounted design for discreet installation in standard wall boxes
• Powered directly from the KNX bus, no additional power supply needed
• Each input supports switching, dimming, blinds control, scene recall, value transmitter, counter, and sequence controller functions
• Configurable operating modes: single-button, two-button, edge-triggered, level-triggered
• Programming via ETS (Engineering Tool Software)
