The binary inputs serve as an interface for operating KNX systems via conventional voltage-loaded push-buttons and switches or for recording potential-free binary signals sent, for example, by door/window contacts or signal contacts.
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.
Potential-free input:
Binary inputs with potential-free inputs:
- Binary input N 262D31, 4 x potential-free 5WG1262-1DB31
- Binary input N 262D51, 8 x potential-free 5WG1262-1DB51
The devices with potential-free input channels are used to record potential-free contacts, the pulsed polling voltage is generated internally.
Potential-free contacts are, for example, door/window contacts or signal contacts.
Voltage input:
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 record 10...230 V AC/DC signals. The following signals can be recorded 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.
