Binary inputs serve as an interface for operating KNX systems via potential-free binary signals recorded by conventional switches or push-buttons, for example.
In addition, the binary inputs are used to record switching or system states, fault or alarm signals, or to count pulses.
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 detect potential-free contacts. The pulsed polling voltage is generated internally.
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.
