Eelectron IO44D02KNX-S KNX push-button interface 4-way, 4 LED outputs, secure

SKU: IO44D02KNX-S
✗ UL Listed
This product has not been certified by an NRTL (UL, ETL, CSA or equivalent). Installation in USA projects may require a Field Evaluation by a recognized laboratory. Consult your local AHJ before specifying.
~ Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an NRTL-listed power supply, many AHJs accept non-listed SELV devices. Verify with your local AHJ before specifying.

The Eelectron IO44D02KNX-S is a flush-mount KNX pushbutton interface with 4 dry-contact inputs and 4 LED outputs in a 34 x 34 x 11 mm housing that fits in any wall box behind a conventional switch or pushbutton. It is the KNX Data Secure version of the IO44D02KNX, for projects that require encrypted group communication from the room level up.

Each input can send switching, dimming, shutter, scene or sequence commands with short/long press detection, the LEDs can follow bus objects or local state, and 16 logic blocks with the Virtual Holder presence function run inside the module. Connection is through a 12-way AWG24 wired connector, and bus consumption stays below 5 mA.

Key Features

  • 4 dry-contact inputs for pushbuttons, switches and contacts; cable up to 10 m (33 ft)
  • 4 LED outputs, 0.5 mA at 3.3 V, for indicator LEDs
  • Input functions: switching, dimming, shutters, scenes, sequences, short/long press
  • 16 logic blocks; Virtual Holder logic for hotel-room presence detection
  • KNX Data Secure
  • Bus-powered, ≤ 5 mA at 21–31 V DC
  • 12-way AWG24 wired connector
  • 34 x 34 x 11 mm, approx. 38 g; 240 group addresses / 280 associations
  • Optional DIN-rail mounting with IOxxD01ACC
