MTN644492 Schneider SpaceLogic KNX Binary input REG-K/4×10 Introduction：
The binary input REG-K/4×10 is used to connect four floating contacts, push-buttons or switches to the KNX bus.
The binary input makes a contact supply voltage (SELV) available which is electrically isolated from the bus voltage. A power supply is thus not necessary for the connected floating contacts.
The binary input has a bus coupler. It is installed on a DIN rail acc. to EN 60715, with the bus connection made via a bus connecting terminal. A data rail is not required.
