Binary inputs serve as an interface for the operation of KNX systems via conventional voltage-loaded push-buttons and switches.

Binary inputs offer both functions that use just one input channel and functions for which two input channels are required. Which adjacent channels are connected for this purpose can be configured in the device settings.

Depending on the function selected for the input channel, it can be defined whether a telegram is sent on a rising edge and/or falling edge, on a short and/or long press of the push-button or on a change of state.

Binary inputs with voltage inputs:

  • Binary input N 263D31, 4 x AC/DC 10…230 V 5WG1263-1DB31
  • Binary input N 263D51, 8 x AC/DC 10…230 V 5WG1263-1DB51

The devices with voltage inputs have far range inputs and are used to detect AC and DC signals from 10...230 V. The following signals can be detected and configured differently so that a different KNX telegram is sent depending on the signal:

  • Voltage is applied
  • Voltage is not applied
  • Voltage increasing
  • Voltage decreasing
  • Voltage pulses

Voltage-loaded contacts are e.g. conventional push-buttons or switches.

The device is a rail-mounted device in N dimension for installation in arrangements and installation on TH 35-mm DIN rails as per standard IEC 60715.

The bus connection of the device uses a bus terminal block. The electronics of the device are supplied via the bus voltage (no additional supply voltage required).

The maintenance-free terminals are designed for the connection of solid or fine-stranded conductors with a conductor cross-section of 0.5 to 2.5 mm² or for the connection of stranded conductors with a conductor cross-section of 2.5 mm². Stranded and fine-stranded conductors can be plugged into the terminals without ferrules.

Direct operating level via membrane keypad with one control button and one status LED per channel. Input states can be simulated via the control buttons The input states are indicated via red status LEDs.
