ELSNER 71122 KNX eTR M2- jet black RAL 9005 2-gang Push Button

The KNX eTR M2 button, code 71122, is a touch-sensitive control device designed for integration into the KNX building bus system. This button is available in deep black RAL 9005 and has a glass surface.

Functionality

The KNX eTR M2 button allows you to control various functions in the KNX system, such as turning on and off lights, controlling devices, adjusting brightness and controlling dimming systems such as curtains, blinds and awnings. Each touch-sensitive button includes a white LED whose behavior can be customized.

Possible Configurations

• Simple button
• Selector
• Dimmer
• Curtain and shutter control (position and slats up/stop or down/stop)
• Awnings control (in/outside/stop)
• Window control (closed/open/firm)
• 8 or 16 bit encoder
• Recalling and storing scenarios

Technical characteristics

The KNX eTR M2 button operates with a nominal voltage of 30 V SELV and has a maximum consumption of 10 mA. The connection is made through KNX terminals with a conductor cross-section of 0.6 to 0.8 mm² and a stripping length of 5 mm, or through spring-loaded terminals with a conductor cross-section of 0.2 to 0.75 mm² for solid and finely woven conductors, and from 0.25 to 0.34 mm² for conductors finely intertwined with ferrules, with a stripping length of 7 to 9 mm.

Integrated sensors

The KNX eTR M2 button includes an integrated temperature sensor, which allows you to receive external temperature readings via bus and process them with your own data to create an overall temperature value.

Communication and Assignments

The device supports up to 183 group addresses and 183 assignments. Communication objects can be connected using AND and OR logics.

Recovery Time

After the bus voltage is restored, the device takes about 5 seconds to receive the data.
