The Siemens binary input device it features 8 potential-free inputs, making it suitable for processing binary signals such as signal contacts and door/window contacts. The inputs have potential-free contacts with internally generated polling voltage for seamless integration into a KNX system. With clear direct operating levels, it allows for easy simulation of input states during commissioning without the need for conventional switches or push-buttons. The device has a wide range of applications including lighting control, solar protection, HVAC control, system state signalling, and pulse counting. Its maintenance-free terminals enable easy connection of solid, stranded, and conductors.
