Description
Introduction
The WEINZIERL KNX IO 512 secure (Art.-Nr. 5491) is a 12-fold bistable 230 V switching actuator engineered for reliable building automation on KNX TP networks. Built within a compact 6-module (108 mm) width footprint, this device belongs to the Weinzierl KNX Block IO platform, delivering high channel density and complete compatibility with ETS 5 and ETS 6. This device is part of our KNX Actuators range.
Designed primarily for LED lighting loads while supporting general load switching and thermal valve control via PWM, the unit integrates native KNX Data Security for encrypted bus communication. Because technical data in this entry is limited, consultants and procurement specialists should verify exact model specifications and BOQ requirements against official Weinzierl technical documentation prior to placing orders.
