ELSNER 71120 KNX eTR M2- signal white RAL 9003 2-gang Push Butt

The KNX eTR M2 button, code 71120, is a touch-sensitive control device designed for integration into the KNX building bus system. This model is available in white RAL 9003.

Key Features

The KNX eTR M2 button has two touch pulsation areas, each equipped with a white LED whose behavior can be customized. Each button can be configured to perform different functions, such as turning lights on and off, controlling devices, adjusting brightness, activating motors, sending values and recalling predefined scenarios.

Configuration functions

• Configurable buttons such as switches, selectors, dimmers, 8 or 16 bit encoders or for recalling and storing scenarios.
• Area function when both buttons are touched, configurable as a switch, selector, 8 or 16 bit encoder or for calling up scenarios.

Sensors and Logic

The KNX eTR M2 button includes an integrated temperature sensor, which can receive external temperature readings via bus and process them with its own data to create a mixed temperature value. In addition, 2 AND logic gates and 2 OR logic gates are available, each with 4 inputs, which can use communication objects as inputs.
