The Weinzierl KNX IO 410.1 secure (Art. 5513, SKU W 410.1) is a 1 TE 4-fold binary input for signals from 12…230 V AC/DC. Inputs are galvanically isolated (<1 mA). The ETS application covers switching, dimming, shutter, valuator, scene and colour control plus operating-time and impulse counters, with 16 independent logic/time blocks and full KNX Data Security.

Bus current is about 3 mA. Two local buttons and three multicolour LEDs support local operation and state display, plus a programming button/LED. Use this module when contacts carry mains or other voltages; for dry contacts / SELV push buttons prefer 411.1. Pair wall plates such as 436 24 V only when voltage class matches the chosen I/O.
