The Siemens binary input is a versatile device that serves as an interface for the operation of KNX systems via conventional voltage-loaded push-buttons and switches. It has 4 inputs for AC/DC signals ranging from 10 to 230 V, offering a wide range of applications for controlling lighting, solar protection, HVAC, and signalling system states. The device features maintenance-free terminals for easy and secure connection of solid, stranded, and fine-stranded conductors. With extensive operating and control functions, such as switching, dimming, and scene control, the binary input can be configured to meet various needs in smart building automation. Its compact and rail-mounted design allows for easy installation on TH 35-mm DIN rails.
