The Eelectron AD84C01KNX is an in-wall KNX multifunction module with 4 digital inputs, 4 digital/analog inputs and 4 LED outputs in a 43 x 36 x 24 mm housing that disappears behind a switch plate. It connects conventional pushbuttons, window contacts and NTC probes to the bus and drives low-current indicator LEDs, which makes it the standard way to KNX-enable a hotel bathroom, a corridor or a retrofit room with existing switches.
The four analog-capable inputs take TS01A01ACC or TS01B01ACC probes on runs up to 20 m, and up to 4 complete thermostat modules run inside the device for towel rails, radiators or fan coils; 5 logic blocks are available for local automation. Connections are 18 cm AWG24 flying leads, and the module draws no more than 10 mA from the bus.
