Comelit KNX 4-Input SELV Module

Comelit CT454020 KNX 4-Input Flush-Mounted Module

The Comelit KNX 4-Input SELV Module integrates conventional switches, push buttons and electrical mechanisms into a KNX-based home automation system. Its concealed installation allows mechanisms from any commercial brand to retain their original appearance.

It features 4 independent SELV digital inputs, configurable to send on/off commands, lighting dimming instructions, blind control commands or scene activations. Each input can generate KNX events when the connected contact opens or closes.

The CT454020 is installed inside a flush-mounted box and supports up to 30 metres of wiring between the module and each switch or push button. It is suitable for new installations, refurbishments and KNX system extensions. It can be combined with shielded KNX bus cable to complete the bus wiring.

This module acts as an interface between mechanical contacts and the KNX bus. It does not switch lights, motors or other electrical loads directly, so the corresponding KNX actuators are required to execute the transmitted commands.
