KNX-BIN24 is a universal module of KNX binary inputs that enables electrical (voltage) signals to be converted into control telegrams for other devices on the bus. These signals may be generated by conventional ON/OFF buttons (to operate lighting, etc.) or by potential-free contacts of devices such as reed switches or sensors of various types of physical quantities (e.g. temperature). The module has 8 physical inputs which allow it to handle 8 independent signals ranging from 0 to 30 V DC and AC.
