The KNX IO 411 (4Ii) is a compact binary input with 4 channels to control lights, shutter etc. with conventional switches or contacts. Inputs are designed for dry contacts. Using as impulse counter is possible as well. It can be used to connect energy meters with S0 output or anemometers.
Two push buttons and three LEDs allow a local operation and a visualization of the device state. In addition to the input channels the device includes 16 independent functions for logic or timer control.
