The OPT-UIx-111 is a compact and flexible KNX universal interface developed for indoor applications. Available in 3, 6, and 9 channel models, it adapts to different project requirements. Each channel can be independently programmed as an input or output. Color coded connection cables enable quick and error-free installation.

Each channel can be independently programmed as an input or output. In input mode, the device detects the status of the connected switch or contact and sends information in the appropriate KNX data type to the KNX bus.

With comprehensive parameter options, it offers a wide range of uses in both small- and large-scale building automation projects. So whether contact scanning is performed on activation or different contact types (maintained/momentary, N.O./N.C.) are used, the device provides maximum flexibility. It also has advanced functions such as transmitting different data types according to different press types (short/long).
