Multifunction Actuator MAXinBOX

A DIN-rail KNX multifunction actuator with 20 outputs rated 16A each and KNX Secure support, for large installations requiring both high channel count and secure communication.

KNX Medium TP (Twisted Pair)

Outputs 20

Key Features

20 outputs, 16A rating; KNX Data Secure support

Typical Applications

Large residential/commercial installations needing high channel-count switching with KNX Security
