CELLIO KNX binary input is a S-mode KNX modular device for rail mounting for connection to the bus of switches and sensors of conventional type (not communicating natively on the KNX bus) equipped with potential-free contacts. In this way, by means of the binary input is possible to switch and control KNX bus functions with normal switches, pushbuttons and sensors or binary signals made available by other devices. The binary input can be used as follows:
– 8 independent channels, for example for the connection of traditional (not bus) switches or pushbuttons dedicated to the switching on/off of loads;
– 4 independent channels, for example for the connection of traditional (not bus) pushbuttons for the control of dimmer or motorized drives.
The device is equipped with an integrated bus communication module and is designed for rail mounting in distribution boards. To operate the device receives an input signal and converts it into a corresponding telegram sent on the bus. The telegram is received and executed by one or more KNX actuators. The device is powered by the KNX bus line with SELV voltage 30 Vdc and requires no auxiliary power supply. The scanning voltage for the input channels is produced inside the device.
