Comelit KNX Actuator with 3 Inputs and 2 16A Outputs

Comelit CT423220 KNX Actuator with 3 Inputs and 2 16A Outputs

The Comelit CT423220 integrates digital signals and controls electrical loads in KNX home and building automation systems. Its compact design combines three inputs and two power outputs for automating lighting, heating, appliances, blinds and other electrical circuits.

It features 3 SELV inputs for conventional push buttons or switches and 2 potential-free relay outputs with a switching capacity of 16A at 230 Vac. The outputs can operate independently or together in binary, blind or thermal valve mode. The bus can be installed using dedicated KNX system cabling.

Its arithmetic logic unit supports conditional operations, timers and counters using internal or external variables. It is particularly suitable for installers who need to combine command input and load switching in a single device, with the option of integrating it with an Iddero VERSO 2 KNX touchscreen.

This actuator is intended for new KNX installations, system extensions or technical replacement of the same model and is not a universal spare part. Loads above 16A require an intermediate contactor, while commissioning and parameter configuration must be completed using ETS.
