The binary input REG-K/8x10 is used to connect eight
floating contacts, push-buttons or switches to the bus
system.
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.
For your safety
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR
ARC FLASH
Safe electrical installation must be carried out only by
skilled professionals. Skilled professionals must prove
profound knowledge in the following areas:
• Connecting to installation networks
• Connecting several electrical devices
• Laying electric cables
• Connecting and establishing KNX networks
• Safety standards, local wiring rules and regulations
Failure to follow these instructions will result in
death or serious injury.
The device may be damaged!
• Never connect the device to an external power
source.
• The binary input circuits must comply with the safety
extra-low voltage conditions (SELV) in accordance
with IEC 60364-4-41.
• Only operate the device according to the specifica-
tions stated in the Technical data.
• All the devices that are installed next to the binary in-
put must be equipped with basic insulation at the very
least.
Failure to follow these instruction can result in
equipment damage.
