N 263D31 KNX Binary Input Module 4xAC/DC 10-230V DIN Rail LED Status Display 5WG1263-1DB31

The KNX binary input module accepts four voltage inputs covering AC/DC 10 to 230 V, making it suitable for connecting active sensors, relay contacts, and voltage signals directly. Each input includes direct operation on the device with LED status indication and a front button to toggle direct mode. Maintenance-free terminals allow easy connection and through-wiring of conductors from 0.5 to 2.5 mm. The device supports up to 100 m twisted-pair cable runs and is powered entirely from the KNX bus. Housed in light grey plastic (RAL 7035) for DIN rail mounting on TH35 per DIN EN 60715, the module fits standard electrical distribution panels.
