N 262D31 KNX Binary Input Module 4x Dry Contacts DIN Rail LED Status Display 5WG1262-1DB31
The KNX binary input module offers four dry contact inputs for capturing potential-free switching states in building automation systems. Each input provides direct operation capability on the device front, with LED status indication and a button to deactivate direct mode. Maintenance-free terminals allow connection and through-wiring of untreated single-core, stranded, or multi-core conductors from 0.5 to 2.5 mm. The device supports twisted-pair cable runs up to 100 m and is bus-powered, requiring no separate auxiliary supply. Housing is made of light grey plastic (RAL 7035) and designed for DIN rail mounting on TH35 according to DIN EN 60715.
Key Functions
- One input object per input for sending state changes
- Adjustable debounce time
- Input locking via blocking objects
- Versatile telegram transmission: switching state, 1-button dimming, solar protection, scene control, value sending, pulse counting with threshold, forced control, and colour temperature control
- Per input pair it supports two-button dimming and shutter/blind control
- Logic operations (AND/OR/NAND/NOR/FILTER/TRIGGER) enable advanced local processing
