![CDATA[The GVS button interfaces enable the integration of EIB/KNX functionality via conventional buttons or switches. They are mounted in 60 mm switch boxes and convert switch operations into switching commands for actuators. With a wide range of functions such as switching, dimming, blind/roller shutter control, scene storage and more. Each channel can be set individually. Technical data: EIB/KNX power supply: 21-30V DC, operating displays: programming button with red LED, green flashing LED in normal operation, input voltage: 230V AC, inputs/outputs: 4 channels can be individually parameterized, max. cable length: 10m, input/output voltage: 5V DC, output current max. 2.5 mA, safety: short-circuit proof, overload protection, reverse polarity protection. Storage/transport temperature: -25°C to +55°C.]]>
