EAE UI108 KNX Universal Interface: 8-Fold Input for Seamless Conventional Integration
With its ultra-compact design, the UI108 is specifically engineered for flush mounting behind existing switches in standard wall boxes, ensuring the aesthetics of the room remain unchanged while upgrading its control capabilities. It is entirely powered by the KNX bus, eliminating the need for an external power supply.
1. Key Features and Versatile Functionality
The EAE UI108 KNX Universal Interface offers 8 independent channels, each capable of being configured for one of six distinct operating modes, providing maximum flexibility for installation.
8-Fold Input Flexibility:
- 8 Independent Channels: Connect up to eight conventional switches or dry-contact devices (e.g., door contacts, level sensors).
- Flush-Mount Design: Designed to be hidden from view inside a switch box, featuring colored connection cables for straightforward wiring.
- Bus-Powered: Operates exclusively on the KNX bus line voltage (21V – 30V DC), simplifying power requirements.
6 Advanced Operating Modes Per Channel:
Each channel can be independently programmed via ETS software for powerful control applications:
- Switching – Standard ON, OFF, or TOGGLE commands.
- Dimming – Control lighting levels with long press for dimming (Brighter/Darker).
- Curtain Control (Shutter Sensor) – Control blinds, shutters, or curtains with commands for Up/Down movement, STOP, and lamella (slat) adjustment.
- Value and Priority – Send 1-byte, 2-byte, or 4-byte values for setpoints or transmit forced operation commands.
- Scene Control – Recall and Save scenes (supports up to 64 scenes).
- Pulse Counter – Utilize the interface to count pulses from conventional meters, with capabilities for Standard and Differential counting.
