N 263D51 KNX Binary Input Module 8xAC/DC 10-230V DIN Rail LED Status Display 5WG1263-1DB51
The KNX binary input module delivers eight voltage inputs across AC/DC 10 to 230 V, allowing direct connection of active sensors, relay contacts, and signal sources. Each input is equipped with a direct operation function and LED status display, controlled by a front-mounted button to enable or disable local operation. Maintenance-free terminals support connection and through-wiring of untreated single-core, stranded, or multi-core conductors from 0.5 to 2.5 mm. The device allows twisted-pair cable runs up to 100 m and is fully bus-powered. The light grey plastic enclosure (RAL 7035) is designed for DIN rail mounting on TH35 according to DIN EN 60715.
Functions
Functions include one input object per input for state-change telegrams, adjustable debounce time, input locking via blocking objects, and extensive adjustable functions:
- Switching state transmission
- 1-button dimming
- Solar protection
- Scene control
- Value sending
- Pulse counting with threshold
- Forced control
- Effect controller
- Group control
- Colour temperature control
Input pairs support two-button dimming with stop telegram and two-button shutter/blind control. Two logic operations per input (AND/OR/NAND/NOR/FILTER/TRIGGER) enable local decision logic, with adjustable transmission delay after bus voltage recovery.
